JWST"s Newfound Galaxies Are the Oldest Ever Seen
We now know that the first galaxies in our universe formed shockingly fast, thanks to the latest results from the James Webb Space Telescope.....»»
Gliese 367 b is a dark and hot sub-Earth with no atmosphere, study finds
Using the James Webb Space Telescope (JWST), astronomers have investigated a nearby sub-Earth exoplanet known as Gliese 367 b. The obtained results indicate that this alien world is dark, hot and lacks a detectable atmosphere. The new findings were p.....»»
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......»»
A day in the life of a mountaintop telescope builder
When she's in Chile, Margaux Lopez starts most days nine thousand feet below her place of work. At 6:30 a.m. she boards a bus to begin the steep climb from La Serena, Chile's second-oldest city, to the top of Cerro Pachón, a mountain in the Chilean.....»»
Australian fossil suggests photosynthesis evolved at least 1.75 billion years ago
The oldest evidence of photosynthetic structures reported to date has been identified inside a collection of 1.75-billion-year-old microfossils, a Nature paper reveals. The discovery helps to shed light on the evolution of oxygenic photosynthesis......»»
The oldest-known version of MS-DOS’s predecessor has been discovered and uploaded
86-DOS would later be bought by Microsoft and take over the computing world. Enlarge / The IBM PC 5150. (credit: SSPL/Getty Images) Microsoft’s MS-DOS (and its IBM-branded counterpart, PC DOS) eventually became softwar.....»»
New ultra-short period binary discovered
Using the Tsinghua University–Ma Huateng Telescopes for Survey (TMTS), an international team of astronomers has discovered a new binary known as TMTS J052610.43+593445.1. The newfound system is an ultrashort-orbital-period binary consisting of a su.....»»
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......»»
Astronomers detect seismic ripples in ancient galactic disk
A new snapshot of an ancient, far-off galaxy could help scientists understand how it formed and the origins of our own Milky Way. At more than 12 billion years old, BRI 1335-0417 is the oldest and furthest known spiral galaxy in our universe......»»
Pancake stack of radioactivity-sensitive films captures most accurate picture of star"s gamma ray beam
A pancake stack of radioactivity-sensitive films carried through the sky by a balloon was able to take the world's most accurate picture of a neutron star's gamma ray beam. To achieve this, Kobe University researchers combined the oldest method of ca.....»»
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.....»»
Mysterious fruit found to be the oldest known fossils of the Frankincense and Myrrh family
Early in the 1970s, a paleontologist working on the outskirts of an Indian village found small, bead-like fossils embedded in the gray chert dotting the surrounding fields. The site was notorious for turning up plant fossils that were difficult to id.....»»
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
Two McMaster astronomers have used recent deep imaging data from the James Webb Space Telescope to look 3.5 billion years into the past to study a remote giant cluster of galaxies......»»
Hubble captures a formation of galaxies neatly lined up
A new Hubble image shows both an interacting galaxy system, and a string of galaxies which happen to line up in a neat procession......»»
