ALMA finds new molecular signposts in starburst galaxy
The ALMA radio telescope has detected more than 100 molecular species, including many indicative of different star formation and evolution processes, in a galaxy where stars are forming much more actively than in the Milky Way. This is far more molecules than were found in previous studies. Now the team will try to apply this knowledge to other galaxies.
Astronomers conduct first search for forming planets with new space telescope
Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly.
Persistent hiccups in a far-off galaxy draw astronomers to new black hole behavior
Astronomers have found that a previously quiet black hole, which sits at the center of a galaxy about 800 million light years away, has suddenly erupted, giving off plumes of gas every 8.5 days before settling back to its normal, quiet state.
Astronomers unveil strong magnetic fields spiraling at the edge of Milky Way's central black hole
A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarized light for the first time, this new view of the monster lurking at the heart of the Milky Way Galaxy has revealed a magnetic field structure strikingly similar to that of the black hole at the center of the M87 galaxy, suggesting that strong magnetic fields may be common to all black holes.
Distant 'space snowman' unlocks mystery of how some dormant deep space objects become 'ice bombs'
Researchers found that the double-lobed object, which is officially named Kuiper Belt Object 486958 Arrokoth and resembles a snowman, may have ancient ices stored deep within it from when the object first formed billions of years ago.
Turbulence within solar transients imaged
Scientists captured images showing the development of turbulence as a Coronal Mass Ejection (CME) interacted with the ambient solar wind in the circumsolar space.
'Cosmic cannibals' expel jets into space at 40 percent the speed of light
Astronomers have measured the speed of fast-moving jets in space, crucial to star formation and the distribution of elements needed for life. The jets of matter, expelled by stars deemed 'cosmic cannibals', were measured to travel at over one-third of the speed of light -- thanks to a groundbreaking new experiment.
Sleeping supermassive black holes awakened briefly by shredded stars
Astronomers have concluded that an obscure class of galaxies known as Compact Symmetric Objects, or CSOs, are not young as previously thought but rather lead relatively short lives.
Tiniest 'starquake' ever detected
An orange dwarf star has yielded the tiniest 'starquakes' ever recorded, measured by an international team of scientists.
Astronomers discover 49 new galaxies in under three hours
New work aimed to study the star-forming gas in a single radio galaxy. Although the team didn't find any star-forming gas in the galaxy they were studying, they instead discovered other galaxies while inspecting the data. In total, the gas of 49 galaxies was detected.
James Webb Space Telescope captures the end of planet formation
How much time do planets have to form from a swirling disk of gas and dust around a star? A new study gives scientists a better idea of how our own solar system came to be.
Signs of life would be detectable in single ice grain emitted from extraterrestrial moons
Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall.
Secrets of the Van Allen belt revealed in new study
A challenge to space scientists to better understand our hazardous near-Earth space environment has been set in a new study.
