Cho Jae-weon, an urban and environmental engineering professor at the Ulsan National Institute of Science and Technology (UNIST), has designed an eco-friendly toilet connected to a laboratory that uses excrement to produce biogas and manure. Reuters reports: The BeeVi toilet -- a portmanteau of the words bee and vision -- uses a vacuum pump to send feces into an underground tank, reducing water use. There, microorganisms break down the waste to methane, which becomes a source of energy for the building, powering a gas stove, hot-water boiler and solid oxide fuel cell. An average person defecates about 500g a day, which can be converted to 50 liters of methane gas, the environmental engineer said. This gas can generate 0.5kWh of electricity or be used to drive a car for about 1.2km (0.75 miles).

Cho has devised a virtual currency called Ggool, which means honey in Korean. Each person using the eco-friendly toilet earns 10 Ggool a day. Students can use the currency to buy goods on campus, from freshly brewed coffee to instant cup noodles, fruits and books. The students can pick up the products they want at a shop and scan a QR code to pay with Ggool.

An anonymous reader quotes a report from Stat News: Death rates are declining for more than half of the most common forms of cancer in the U.S., according to a sweeping annual analysis released Thursday. The new report -- released by the American Cancer Society, the National Cancer Institute, the Centers for Disease Control and Prevention, and other collaborators -- found that between 2014 and 2018, death rates dropped for 11 out of 19 of the most common cancers among men and 14 of the 20 most prevalent cancers among women.

Accelerating declines in lung cancer deaths may account for much of the overall progress seen in recent years, the authors of the report said. Over the past two decades, the death rate for lung cancer has declined even faster than the rate at which patients are diagnosed with the disease. And while part of the early success in preventing lung cancer can be attributed to the massive drop in smoking rates, the authors note the most recent downward trends seem to correspond with the approval of new treatments for non-small cell lung cancer that improved the likelihood of survival. Death rates from melanoma also saw an accelerated decline in the past decade, despite a growing number of diagnoses. Like in lung cancer, authors point to the introduction of novel treatments around the same time as the turnaround on the death rate. New targeted and immune checkpoint inhibitors were approved by the Food and Drug Administration in 2011, one year before major declines in death rates were seen in women and two years before they were seen in men.

While the report showed improved survival rates for many patients over recent years, others, such as prostate, colorectal, or female breast cancers, have seen progress stalled or stopped. Breast cancer continues to be one of the three deadliest cancers for women of all races, and the most frequently fatal cancer for Hispanic women. While the rates of death from breast cancer are declining, the pace of the decline has slowed over the past two decades, according to the report. And across the board, racial health disparities persist. Black women and white women are diagnosed with breast cancer at similar rates, but the mortality rate for Black women is 40% higher. Overall, cancer is more common among white individuals than Black individuals, but Black people die from cancer at higher rates. [The report] emphasized the importance of preventive measures for certain cancers, noting that while cancers related to smoking have continued to decrease, those related to excess body weight have increased. Early and consistent access to screenings has also been critical, as demonstrated by the apparent effect of adapted screening guidelines for colorectal cancer.

Yesterday, Moderna announced that the first set of volunteers in a clinical trial have received its mRNA-based seasonal flu vaccine. The Verge reports: Before the COVID-19 pandemic, mRNA vaccines were still largely experimental, even as they were heralded as the future of vaccine development. People who get an mRNA vaccine are injected with tiny snippets of genetic material from the target virus. Their cells use that genetic information to build bits of the virus, which the body's immune system learns to fight against. The high efficacy of the mRNA COVID-19 vaccines made by Moderna and Pfizer / BioNTech was a major endorsement for this type of vaccine. Now, pharmaceutical companies plan to use this technology to fight other types of infectious diseases, including flu.

The flu shots available each year in the United States are usually between 40 and 60 percent effective. The most common shots are made by growing the influenza virus in cells or chicken eggs, and then killing the virus so it's no longer dangerous. It takes a long time to grow the virus, so companies have to start making the shots around six months ahead of time, based on predictions around which strain of the flu will be circulating that year. Pharmaceutical companies hope that mRNA-based flu vaccines can be more effective than the traditional shots. Because they'd be faster to make, production wouldn't have to start so far in advance, and they could theoretically be more closely matched with the type of flu spreading each season.

To stay warm in frigid seas, the marine mammals rely on an unexpected use of the powerhouses of their cells. From a report: Sea otters run hot. It's not just a manner of speaking: Scientists have found that the furry mammals' metabolisms work at a rate three times what might normally be expected from a creature their size, burning swiftly through calories. They seem to be using much of that energy to generate heat, keeping themselves at a toasty 98.6 degrees Fahrenheit in the frigid ocean, where staying warm is a matter of life and death. But the details of their conversion of food and oxygen into vast reserves of heat have been obscure. Now researchers studying sea otters' muscles report that the feat involves using the mitochondria in their muscle cells in an unexpected way. Their study was published Thursday in the journal Science.

Unlike whales and polar bears, sea otters don't have a thick insulating layer of blubber, and their celebrated fur -- the thickest in the world, with up to 2.6 million hairs per square inch -- is not enough on its own to keep them alive in an ocean that can hover on the edge of freezing. Muscles generate heat as they contract, but scientists have known for some time there is another way that muscles can help animals keep warm, a cellular process with the delightful name of proton leak. Inside almost all animal cells, little pill-shaped organelles called mitochondria break down sugar molecules to extract energy. (Mitochondria are often called the powerhouses of the cell.) During the final stage of this process, protons pop through a membrane. In biology textbooks, the protons helpfully trickle through tiny spinning pores, driving them like water wheels to make adenosine triphosphate, a compound that serves as the molecular battery powering cellular processes.

The risk of pathogens spilling over from wildlife trade and farmed animals into humans should be key considerations in efforts to prevent the next pandemic, research suggests. From a report: Researchers have been assessing the risks of the different ways that disease-causing organisms jump from animals to humans in an effort to characterise and address the risk of the next pandemic. In a study published in the journal Biological Reviews, University of Cambridge scientists found that while the risk of another pandemic cannot be eliminated, systemic changes in the way we interact with animals, in general, could substantially minimise the probability.

The risks are not just linked to exotic wild animals, they caution. "There's a natural tendency, particularly in the western world, to imagine that this has nothing to do with us. It's something remote and exotic ⦠something that someone else has been doing," said the study's lead author Dr Silviu Petrovan, a veterinarian and wildlife expert at Cambridge. "I suppose what most people have in their minds is not the venison that they buy in Waitrose -- which, of course, is wildlife -- but rather something altogether more exotic."

Indian scientists have discovered a new plant species in Antarctica. From a report: Polar biologists stumbled upon a species of moss during an expedition to the ice-covered continent in 2017. Identification is laborious, and it took the scientists five years to confirm that the species had been discovered for the first time. The peer-reviewed paper describing this discovery has been accepted in the leading international journal, Journal of Asia-Pacific Biodiversity. The biologists, based in the Central University of Punjab, have named the specie Bryum Bharatiensis. Bharati is the Hindu goddess of learning and the name of one of India's Antarctic research stations. Prof Felix Bast, a biologist who was part of the six-month-long expedition to the continent - the 36th by Indian scientists - discovered the dark green specie at Larsemann Hills, overlooking the Southern Ocean, in January 2017. This is located near Bharati, one of the remotest research stations in the world.

An anonymous reader writes: One in five Americans uses a Fitbit, Apple Watch or other wearable fitness tracker. And over the past year, several studies have suggested that the devices -- which can continually collect data on heart rates, body temperature, physical activity and more -- could help detect early signs of Covid-19 symptoms. Now, research suggests that these wearables can also help track patients' recovery from the disease, providing insight into its long-term effects. In a paper published on Wednesday in the journal JAMA Network Open, researchers studying Fitbit data reported that people who tested positive for Covid-19 displayed behavioral and physiological changes, including an elevated heart rate, that could last for weeks or months. These symptoms lasted longer in people with Covid than in those with other respiratory illnesses, the scientists found.

The new study focuses on a subset of 875 Fitbit-wearing participants who reported a fever, cough, body aches or other symptoms of a respiratory illness and were tested for Covid-19. Of those, 234 people tested positive for the disease. The rest were presumed to have other kinds of infections. Participants in both groups slept more and walked less after they got sick, and their resting heart rates rose. But these changes were more pronounced in people with Covid-19. "There was a much larger change in resting heart rate for individuals who had Covid compared to other viral infections," said Jennifer Radin, an epidemiologist at Scripps who leads the DETECT trial. "We also have a much more drastic change in steps and sleep." The scientists also found that about nine days after participants with Covid first began reporting symptoms, their heart rates dropped. After this dip, which was not observed in those with other illnesses, their heart rates rose again and remained elevated for months. It took 79 days, on average, for their resting heart rates to return to normal, compared with just four days for those in the non-Covid group.

This prolonged heart rate elevation may be a sign that Covid-19 disrupts the autonomic nervous system, which regulates basic physiological processes. The heart palpitations and dizziness reported by many people who are recovering from Covid may be symptoms of this disruption. Sleep and physical activity levels also returned to baseline more slowly in those with Covid-19 compared to those with other ailments, Dr. Radin and her colleagues found. The researchers identified a small subset of people with Covid whose heart rates remained more than five beats per minute above normal one to two months after infection. Nearly 14 percent of those with the disease fell into this category, and their heart rates did not return to normal for more than 133 days, on average. These participants were also significantly more likely to report having had a cough, shortness of breath and body aches during the acute phase of their illness than did other Covid patients.

The UK's most powerful supercomputer, which its creators hope will make the process of preventing, diagnosing and treating disease better, faster and cheaper, is operational. The Guardian reports: Christened Cambridge-1, the supercomputer represents a $100m investment by US-based computing company Nvidia. The idea capitalizes on artificial intelligence (AI) -- which combines big data with computer science to facilitate problem-solving -- in healthcare. [...] Cambridge-1's first projects will be with AstraZeneca, GSK, Guy's and St Thomas' NHS foundation trust, King's College London and Oxford Nanopore. They will seek to develop a deeper understanding of diseases such as dementia, design new drugs, and improve the accuracy of finding disease-causing variations in human genomes.

A key way the supercomputer can help, said Dr Kim Branson, global head of artificial intelligence and machine learning at GSK, is in patient care. In the field of immuno-oncology, for instance, existing medicines harness the patient's own immune system to fight cancer. But it isn't always apparent which patients will gain the most benefit from these drugs -- some of that information is hidden in the imaging of the tumors and in numerical clues found in blood. Cambridge-1 can be key to helping fuse these different datasets, and building large models to help determine the best course of treatment for patients, Branson said.

An anonymous reader quotes a report from Phys.Org: Scientists at KAIST have fabricated a laser system that generates highly interactive quantum particles at room temperature. Their findings, published in the journal Nature Photonics, could lead to a single microcavity laser system that requires lower threshold energy as its energy loss increases. The system, developed by KAIST physicist Yong-Hoon Cho and colleagues, involves shining light through a single hexagonal-shaped microcavity treated with a loss-modulated silicon nitride substrate. The system design leads to the generation of a polariton laser at room temperature, which is exciting because this usually requires cryogenic temperatures.

The researchers found another unique and counter-intuitive feature of this design. Normally, energy is lost during laser operation. But in this system, as energy loss increased, the amount of energy needed to induce lasing decreased. Exploiting this phenomenon could lead to the development of high efficiency, low threshold lasers for future quantum optical devices. [...] The key is the design and materials. The hexagonal microcavity divides light particles into two different modes: one that passes through the upward-facing triangle of the hexagon and another that passes through its downward-facing triangle. Both modes of light particles have the same energy and path but don't interact with each other. However, the light particles do interact with other particles called excitons, provided by the hexagonal microcavity, which is made of semiconductors. This interaction leads to the generation of new quantum particles called polaritons that then interact with each other to generate the polariton laser. By controlling the degree of loss between the microcavity and the semiconductor substrate, an intriguing phenomenon arises, with the threshold energy becoming smaller as energy loss increases.

NASA's next big space telescope just took a big step forward toward its planned launch this fall. From a report: The $9.8 billion James Webb Space Telescope mission has passed a key launch review, keeping it on track to lift off atop an Ariane 5 rocket before the end of the year, European Space Agency (ESA) officials announced last week. "This major milestone, carried out with Arianespace, the Webb launch service provider, confirms that Ariane 5, the Webb spacecraft and the flight plan are set for launch," ESA officials wrote in a July 1 update. "It also specifically provides the final confirmation that all aspects of the launch vehicle and spacecraft are fully compatible."

While Webb is primarily a NASA mission, ESA and the Canadian Space Agency (CSA) are important partners. The CSA is providing the telescope's guidance sensor and one of its scientific instruments. ESA is contributing some science gear to the mission as well and is also providing launch services, procuring the Ariane 5 heavy lifter to get Webb off the ground. The launch will take place from Europe's Spaceport in Kourou, French Guiana. Mission teams are working toward a launch readiness date of Oct. 31, but liftoff is not expected to actually take place on Halloween. "The precise launch date following 31 October depends on the spaceport's launch schedule and will be finalized closer to the launch readiness date," ESA officials wrote in the same statement.

The University of Oxford this week started vaccinations of a novel HIV vaccine candidate as part of a Phase I clinical trial in the UK. From a report: The goal of the trial, known as HIV-CORE 0052, is to evaluate the safety, tolerability, and immunogenicity of the HIVconsvX vaccine -- a mosaic vaccine targeting a broad range of HIV-1 variants, making it potentially applicable for HIV strains in any geographical region. Thirteen healthy, HIV-negative adults, aged 18-65 and who are considered not to be at high risk of infection, will initially receive one dose of the vaccine followed by a further booster dose at four weeks. The trial is part of the European Aids Vaccine Initiative (EAVI2020), an internationally collaborative research project funded by the European Commission under Horizon 2020 health programme for research and innovation.

Professor Tomas Hanke, Professor of Vaccine Immunology at the Jenner Institute, University of Oxford, and lead researcher on the trial, said: 'An effective HIV vaccine has been elusive for 40 years. This trial is the first in a series of evaluations of this novel vaccine strategy in both HIV-negative individuals for prevention and in people living with HIV for cure.' While most HIV vaccine candidates work by inducing antibodies generated by B-cells, HIVconsvX induces the immune system's potent, pathogen obliterating T cells, targeting them to highly conserved and therefore vulnerable regions of HIV -- an "Achilles heel" common to most HIV variants.

An anonymous reader shares a report: As we carefully map the stars of our Milky Way, we're able to identify features that tell us of its history. These include local details, such as the stars that have passed through an area from which something would be able to detect Earth. And it includes far larger structures, like the trails of stars left behind by smaller galaxies that have merged with our own. But one feature we've discovered has been a bit confusing: trails of stars that are too small and thin to have come from a galaxy collision. There are dozens of them that we've not identified a source for. Their size suggests they came from a globular cluster, but there's no obvious mechanism for these clusters to eject stars at a rate sufficient to generate this sort of stream. Now, a team of researchers has suggested a not-so-obvious mechanism: Over time, clusters may become dominated by black holes that eject all the stars.

Globular clusters are dense groups of stars that orbit the Milky Way together. They're held in association by their mutual gravity. Complex interactions will inevitably eject some of the stars, but not at an appreciable rate, which makes the clusters extremely long-lived. The researchers started their work, however, by looking at an unusual globular cluster called Palomar 5. It has both extended tails of lost stars, and its total mass is relatively small, making it diffuse compared to other clusters we've studied. The lower density makes it easier for Palomar 5 to lose stars, but it could also have been caused by past star loss, creating a bit of a chicken-and-egg problem. So, the researchers decided to model globular cluster evolution and try to find a model that could produce something that looks like Palomar 5. The researchers created a model that takes a cluster of stars and models their gravitational interactions with each other and the Milky Way as they orbit the galactic center. Thanks to some help from a cluster of GPUs and the right software, they were able to run these simulations for billions of years. By changing the parameters, they could find which factors were associated with clusters that ended up looking like Palomar 5.

A team of Korean scientists may have found a way to desalinate seawater in minutes. An anonymous reader quotes a report from Interesting Engineering: When using membranes to filter seawater, the membrane must remain dry for long periods of time. If the membrane becomes wet, the filtration process becomes ineffective and allows large amounts of salt to pass through the membrane. For long term operations, progressive membrane wetting has been observed regularly, which be resolved by changing the membrane. Researcher Yunchul Woo and his team at the Korea Institute of Civil Engineering and Building Technology (KICT) have now developed a membrane that is less susceptible to wetting and is stable in the long term.

The membrane is made of nanofibers that have been fabricated into a three-dimensional hierarchical structure, This was achieved by using a type of nanotechnology called electrospinning. Using this technology, the researchers were able to fabricate a membrane that is highly hydrophobic -- i.e. water repellent. The hydrophobic nature of the membrane is helpful because it is designed to not allow water molecules to pass. Instead, a temperature difference is applied on the two sides of the membrane that causes water from one end to evaporate into water vapor. The membrane allows water vapor to pass, which then condenses onto the cooler side. Called, membrane distillation, this is a commonly used method of desalination using membranes. Since the salt particles are not converted to the gaseous state, they are left out on one side of the membrane, giving highly purified water on the other side. The Korean researchers also used silica aerogel in their membrane fabrication process which further enhanced the flow of water vapor through the membrane, providing quicker access to desalinated water. The team tested their technology for continuous operation for 30 days and found that the membrane continued to filter out 99.9 percent salt without any wetting issues. The study has been published in the Journal of Membrane Science.

NASA announced on Monday that Ingenuity's ninth flight was a success, as it undertook a "high-speed flight across unfriendly terrain." The Hill reports: Ingenuity flew for 166.4 seconds at a pace of 5 meters per second over a terrain of high slopes -- all new records for the helicopter. In preparation for the flight, NASA said, "First, we believe Ingenuity is ready for the challenge, based on the resilience and robustness demonstrated in our flights so far. Second, this high-risk, high-reward attempt fits perfectly within the goals of our current operational demonstration phase. A successful flight would be a powerful demonstration of the capability that an aerial vehicle (and only an aerial vehicle) can bring to bear in the context of Mars exploration -- traveling quickly across otherwise untraversable terrain while scouting for interesting science targets."

Tantalizing evidence has been uncovered for a mysterious population of "free-floating" planets, planets that may be alone in deep space, unbound to any host star. The results include four new discoveries that are consistent with planets of similar masses to Earth, published today in Monthly Notices of the Royal Astronomical Society. Phys.Org reports: The study, led by Iain McDonald of the University of Manchester, UK, (now based at the Open University, UK) used data obtained in 2016 during the K2 mission phase of NASA's Kepler Space Telescope. During this two-month campaign, Kepler monitored a crowded field of millions of stars near the center of our Galaxy every 30 minutes in order to find rare gravitational microlensing events. The study team found 27 short-duration candidate microlensing signals that varied over timescales of between an hour and 10 days. Many of these had been previously seen in data obtained simultaneously from the ground. However, the four shortest events are new discoveries that are consistent with planets of similar masses to Earth. These new events do not show an accompanying longer signal that might be expected from a host star, suggesting that these new events may be free-floating planets. Such planets may perhaps have originally formed around a host star before being ejected by the gravitational tug of other, heavier planets in the system. Confirming the existence and nature of free-floating planets will be a major focus for upcoming missions such as the NASA Nancy Grace Roman Space Telescope, and possibly the ESA Euclid mission, both of which will be optimized to look for microlensing signals.

Most people in the poorest countries will need to wait another two years before they are vaccinated against COVID-19, researchers have told Nature. From a report: Around 11 billion doses are needed to fully vaccinate 70% of the world's population against COVID-19. As of 4 July, 3.2 billion doses had been administered. At the current vaccination rate, this will increase to around six billion doses by the end of the year, researchers from the International Monetary Fund, based in Washington DC, project. But so far, more than 80% of the doses have gone to people in high-income and upper-middle-income countries. Only 1% of people in low-income countries have been given at least one dose, according to the website Our World in Data.

Last month, the leaders of the G7 group of wealthy nations pledged extra doses for low- and middle-income countries (LMICs) by the end of 2022, at a summit in Cornwall, UK. The centrepiece was a promise from US President Joe Biden to donate 500 million doses of the vaccine made by pharmaceutical company Pfizer of New York City and biotechnology company BioNTech in Mainz, Germany. This is in addition to 87.5 million previously pledged. The United Kingdom pledged 100 million, and France, Germany and Japan have pledged around 30 million each.

It's far from a done deal, but plans by European physicists to build a huge new gravitational wave observatory with a radical design received a boost last week. From a report: The European Strategy Forum on Research Infrastructures (ESFRI), which advises European governments on research priorities, added the $2.25 billion observatory, called the Einstein Telescope, to a road map of large science projects ripe for progress. Developers hope the move will give them the political validation needed to transform the Einstein Telescope idea into a project. "This isn't a promise of any funding, but it shows the clear intention to pursue this," says Harald Luck, a gravitational wave physicist at Leibniz University Hannover and the Max Planck Institute for Gravitational Physics and co-chair of the Einstein Telescope steering committee. âoeIt is more of a political commitment."

U.S. gravitational wave physicists welcomed the announcement, too, as they think it may bolster their plans to build a pair of detectors even bigger than the Einstein Telescope in a project called Cosmic Explorer. "In the U.S., I think the momentum is going to start to build," says David Reitze, executive director of the Laser Interferometer Gravitational-Wave Observatory (LIGO) and a physicist at the California Institute of Technology.

Endurance22 will launch early next year with aim of locating and surveying wreck in the Weddell Sea. From a report: The location of Sir Ernest Shackleton's Endurance has been one of the great maritime mysteries since the ship became trapped in ice and sank in 1915. Finding this symbol of the "heroic age" of polar exploration at the bottom of the Weddell Sea was long thought impossible because of the harshness of the Antarctic environment -- "the evil conditions," as Shackleton described them. Now a major scientific expedition, announced on Monday, is being planned with a mission to locate, survey and film the wreck. Endurance22 will launch early next year, in a vessel that will brave the most treacherous frozen waters, pounding its way through miles of pack ice. The effects of climate change will make the expedition a little less difficult, with melting ice easing the vessel's passage. An international team of scientists with expertise in the study of ice and climate will be onboard, advancing knowledge of the Antarctic environment.

Mensun Bound, its director of exploration, headed the 2019 search for the Endurance that had to be called off because of extreme weather conditions, after an underwater vehicle became trapped beneath the ice. He told the Guardian: "There's a complexity of emotions all swishing around within me. On the one hand, there's great excitement. On the other, for the last three years, I've had to carry this persistent sadness in me that we didn't find it last time. It's never far from my thoughts. That ship is always teasing my imagination." Bound said global warming in the Antarctic is "absolutely devastating," but that the melting ice "has improved our chances" of discovering the shipwreck.

India's CNN-News18 reports: [P]revious research has found that how cells pick a particular repair strategy can be influenced by the microgravity conditions in space. Scientists are concerned that DNA repairs influenced by microgravity conditions may not be adequate, and can lead to harmful consequences. To study the DNA repair process in space, scientists have developed a new technique that uses CRISPR/Cas9 — a gene-editing technology — to recreate precise damages so that cells can be observed repairing them. The team of researchers led by Sarah Stahl-Rommel has successfully demonstrated the technique and its viability aboard the International Space Station.
"CRISPR gene editing is no longer confined to Earth," reports Engadget: The new approach clears the way for other research around DNA repair in space. With enough work, the scientists hope they can replicate the genetic damage from ionizing radiation, not to mention other effects from long-term spaceflight. That, in turn, could help NASA and other agencies develop technology that shields astronauts and makes deep space exploration practical. There's a chance CRISPR might play an important role in getting humans to Mars and beyond.

For three weeks the "payload computer" has been down on NASA's Hubble Space Telescope, and "Without it, the instruments on board meant to snap pictures and collect data are not currently working," NPR recently reported. But as this weekend approached, NASA made an announcement...

NASA confirmed that there is a procedure for turning on the telescope's backup hardware, and that in the coming week it will first test those crucial procedures. (In the past week NASA has "completed preparations" for those tests.) After more than 30 years in space, "the telescope itself and science instruments remain healthy and in a safe configuration," NASA confirmed this week. But while they've now suspended new scientific observations, images already collected by the telescope are still being analyzed, reports Space.com — including one image with all the colors of the American flag released just before the holiday celebrating the country's founding as an independent nation: The Hubble Space Telescope has captured a dazzling view of a distant star cluster, one filled with stars that sparkle in red, white and blue, unveiled just in time for the Fourth of July U.S. holiday.

The photo, which NASA and the European Space Agency released July 2, shows the open star cluster NGC 330, a group of stars located about 180,000 light-years away in the Small Magellanic Cloud, a dwarf satellite galaxy to our own Milky Way, in the constellation Tucana, the Toucan... Astronomers used archived observations from Hubble's Wide Field Camera 3 in 2018 to create this image to support two different studies aimed at understanding how star clusters evolve and how large stars can grow before they explode as supernovas.

"The most stunning object in this image is actually the very small star cluster in the lower left corner of the image, surrounded by a nebula of ionised hydrogen (red) and dust (blue)," ESA officials said in a separate image description. " Named Galfor 1, the cluster was discovered in 2018 in Hubble's archival data, which was used to create this latest image from Hubble."
And today NASA also tweeted out an image of "the Fireworks Galaxy," the spiral galaxy Caldwell 12 with an unprecedented 10 supernovae observed since 1917.
