Webb captures rarely seen prelude to a supernova
A Wolf-Rayet star is a rare prelude to the famous final act of a massive star: the supernova. As one of its first observations in 2022, the NASA/ESA/CSA James Webb Space Telescope captured the Wolf-Rayet star WR 124 in unprecedented detail. A distinc.....»»
James Webb observes extremely hot exoplanet with 5,000 mph winds

Japanese aerospace company captures an actual picture of space debris
Space debris is a growing problem, so companies are working on ways to mitigate it. A new satellite called ADRAS-J was built and launched to demonstrate how a spacecraft could rendezvous with a piece of space junk, paving the path for future removal......»»
Webb telescope probably didn"t find life on an exoplanet—yet
Recent reports of NASA's James Webb Space Telescope finding signs of life on a distant planet understandably sparked excitement. A new study challenges this finding, but also outlines how the telescope might verify the presence of the life-produced g.....»»
NASA/JAXA"s XRISM mission captures unmatched data with just 36 pixels

James Webb Space Telescope data pinpoint possible aurorae on a cold brown dwarf
Using new observations from the James Webb Space Telescope (JWST), astronomers have discovered methane emission on a brown dwarf, an unexpected finding for such a cold and isolated world. Published in the journal Nature, the findings suggest that thi.....»»
Northern permafrost region emits more greenhouse gases than it captures, study finds
Permafrost underlies about 14 million square kilometers of land in and around the Arctic. The top 3 meters contain an estimated 1 trillion metric tons of carbon and 55 billion metric tons of nitrogen. Historically, the northern permafrost region has.....»»
Physicists solve puzzle about ancient galaxy found by Webb telescope
Last September, the James Webb Space Telescope, or JWST, discovered JWST-ER1g, a massive ancient galaxy that formed when the universe was just a quarter of its current age. Surprisingly, an Einstein ring is associated with this galaxy. That's because.....»»
A supernova caused the BOAT gamma ray burst, JWST data confirms
But astronomers puzzled by the lack of signatures of expected heavy elements. Enlarge / Artist's visualization of GRB 221009A showing the narrow relativistic jets—emerging from a central black hole—that gave rise to the brig.....»»
Novel tech captures disease markers in a snap: The future of early diagnosis
Extracellular vesicles (EVs) have emerged as promising biomarkers for non-invasive disease diagnostics, offering an alternative to conventional biopsies. However, the challenge has been the efficient and pure isolation of EVs from biological fluids,.....»»
Fining big polluters can reduce environmental damage, but only if the fines match the crimes
Some of Canada's biggest employers have a poor track record of abiding by environmental laws. When laws are broken corporate leaders don't go to prison; instead, the company is fined. But the fines are rarely severe enough to scare them into changing.....»»
