March 28th, 2024 11:10:29 EDT -0400 Unlocking supernova stardust secrets
New research has discovered a rare dust particle trapped in an ancient extra-terrestrial meteorite that was formed by a star other than our sun.
March 28th, 2024 11:10:18 EDT -0400 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.
March 27th, 2024 15:49:54 EDT -0400 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.
March 27th, 2024 15:49:13 EDT -0400 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.
March 27th, 2024 12:46:32 EDT -0400 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.
March 27th, 2024 12:46:27 EDT -0400 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.
March 27th, 2024 12:45:48 EDT -0400 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.
March 27th, 2024 12:34:57 EDT -0400 '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.
March 26th, 2024 17:01:17 EDT -0400 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.
March 26th, 2024 10:39:08 EDT -0400 Tiniest 'starquake' ever detected
An orange dwarf star has yielded the tiniest 'starquakes' ever recorded, measured by an international team of scientists.
March 25th, 2024 11:41:18 EDT -0400 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.
March 22nd, 2024 14:55:54 EDT -0400 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.

Jan 2013 - Two comets to get excited about. One is Comet PANSTARRS, which will be brightest in March 2013. The other is Comet ISON, which might become a daylight comet in late 2013. Although a comet’s movement in our sky can be predicted, its brightness cannot be. It’s too early to know whether Comet PANSTARRS or Comet ISON – the two exciting comets of 2013 – will dazzle or fizzle.

Comet PANSTARRS
By October 2012, its surrounding coma was seen to be large and fine at an estimated 75,000 miles (120,000 kilometers) wide. In March 2013, by some estimates, this comet should get as bright as Venus,

Comet ISON
Last year, Russian astronomers Vitaly Nevsky and Artyom Novichonok discovered a new gigantic comet that is currently approaching Earth. The ISON comet, which is expected to become brighter than the full moon, will be visible to the naked eye by late 2013.

Comet ISON has only been visible through powerful telescopes. In November 2013, heat from the sun will vaporize ices in the comet's body, creating what could be a spectacular tail that will be visible in Earth's night sky without telescopes or even binoculars from about October 2013 through January 2014.

Comet ISON will come within 800,000 miles (1.2 million km) of our sun’s surface on November 28. That’s over 100 times closer to the sun than Earth. This close pass to the sun might cause Comet ISON to break to pieces. January 2014 may see a meteor shower produced by streams of debris from the ISON comet.
