Hubble images a pair of galaxies caught in the process of merging
The two galaxies shown in the image, NGC 6040 and LEDA 59642, are so close that they are interacting and have a shared name as a pair, Arp 122......»»
Scientists come up with technology to recycle used clothes rather than simply burning them
When you go running in the woods in your running tights, elastane is the reason they fit you so comfortably. Elastane is an elastic material that allows the fabric to stretch and adapt to your body......»»
Astronomers find spark of star birth across billions of years
Astronomers have completed the largest and most detailed study of what triggers stars to form in the universe's biggest galaxies, using NASA's Chandra X-ray Observatory and other telescopes. They were surprised to find that the conditions for stellar.....»»
Another example of a fantastic Einstein ring
The most evocative astronomy images take us across space and time to stars and galaxies billions of light-years away. Nestled at the center of this one, taken by the Hubble Space Telescope, is a collection of three galaxies. They're not all that clos.....»»
NASA scientists discover a novel galactic "fossil"
Researchers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, have discovered X-ray activity that sheds light on the evolution of galaxies......»»
Astronomers think they finally know origin of enormous “cosmic smoke rings“
Massive stars burn out quickly. When they die, they expel their gas as outflowing winds. Enlarge / Odd radio circles are large enough to contain galaxies in their centers and reach hundreds of thousands of light years across. (c.....»»
Unexpectedly massive black holes dominate small galaxies in the distant universe
Astronomers have discovered that the supermassive black holes in the centers of early galaxies are much more massive than expected. These surprisingly hefty black holes offer new insights into the origins of all supermassive black holes, as well as t.....»»
"Blob-like" home of farthest-known fast radio burst is collection of seven galaxies, researchers find
In summer 2022, astronomers detected the most powerful fast radio burst (FRB) ever observed. And coming from a location that dates halfway back to the Big Bang, it also was the farthest known FRB spotted to date......»»
Space oddity: Uncovering the origin of the universe"s rare radio circles
It's not every day astronomers say, "What is that?" After all, most observed astronomical phenomena are known: stars, planets, black holes and galaxies. But in 2019 the newly completed ASKAP (Australian Square Kilometer Array Pathfinder) telescope pi.....»»
Hubble captures a busy frame of four overlapping spiral galaxies
This week's image from the Hubble Space Telescope shows a host of galaxies all overlapping each other in a complex swirl......»»
The early universe was surprisingly filled with spiral galaxies, research suggests
If we could travel far beyond our galaxy, and look back upon the Milky Way, it would be a glorious sight. Luminous spirals stretching from a central core, with dust and nebulae scattered along the spiral edges. When you think about a galaxy, you prob.....»»
Hubble captures throng of spiral galaxies
This Hubble Picture of the Week features a richness of spiral galaxies: the large, prominent spiral galaxy on the right side of the image is NGC 1356; the two apparently smaller spiral galaxies flanking it are LEDA 467699 (above it) and LEDA 95415 (v.....»»
JWST sets a new record, sees newly forming stars in the Triangulum galaxy
Our Milky Way bristles with giant molecular clouds birthing stars. Based on what we see here, astronomers assume that the process of star creation also goes on similarly in other galaxies. It makes sense since their stars have to form somehow. Now, t.....»»
New study shows Small Magellanic Cloud is actually two smaller galaxies
A large international team of astronomers and astrophysicists has found evidence showing that the Small Magellanic Cloud is not a single galaxy—it is actually two, one behind the other. The group has written a paper describing their work and posted.....»»
Researchers study a million galaxies to find out how the universe began
A team of researchers has analyzed more than 1 million galaxies to explore the origin of the present-day cosmic structures, as reported in a recent study published in Physical Review D as an Editors' Suggestion......»»
Webb spots a second lensed supernova in a distant galaxy
In November 2023, the James Webb Space Telescope observed a massive cluster of galaxies named MACS J0138.0-2155. Through an effect called gravitational lensing, first predicted by Albert Einstein, a distant galaxy named MRG-M0138 appears warped by th.....»»
Galaxy-scale winds spotted in the distant Universe
These winds can drive gas out of galaxies, shaping their future evolution. Enlarge / X-ray emissions (purple) superimposed on a visible light image of a galaxy shows the galaxy winds being launched. (credit: X-ray: NASA/CXC/The O.....»»
Scientists discover how to degrade and reform thermoset polymers without loss of function
A team of UK scientists has got a step closer to making several different types of plastic much easier to recycle using a method that could be applied to a whole range of difficult-to-recycle polymers, including rubbers, gels, and adhesives......»»
Dark matter might be keeping an even darker secret
Researchers compare a theorized behavior of dark matter to actual galaxies. Enlarge / A compact dwarf galaxy, which may have features that are difficult to explain with standard models of dark matter. (credit: ESA/Hubble & NASA).....»»
Astronomers look billions of years into the past to study Pandora"s Cluster
