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.....»»
Astronomers investigate the atmosphere of a nearby cold brown dwarf
Using the James Webb Space Telescope (JWST), astronomers have observed a nearby cold brown dwarf designated WISEPA J182831.08+265037.8 (or WISE 1828 for short). The observations delivered important insights into the composition of the object's atmosp.....»»
"Beyond what"s possible": New JWST observations unearth mysterious ancient galaxy
Our understanding of how galaxies form and the nature of dark matter could be completely upended after new observations of a stellar population bigger than the Milky Way from more than 11 billion years ago that should not exist......»»
New NASA mission will study ultraviolet sky, stars, stellar explosions
As NASA explores the unknown in air and space, a new mission to survey ultraviolet light across the entire sky will provide the agency with more insight into how galaxies and stars evolve. The space telescope, called UVEX (UltraViolet EXplorer), is t.....»»
Discovery of unexpected ultramassive galaxies may not rewrite cosmology, but still leaves questions
Ever since the James Webb Space Telescope (JWST) captured its first glimpse of the early universe, astronomers have been surprised by the presence of what appear to be more "ultramassive" galaxies than expected. Based on the most widely accepted cosm.....»»
Image: Spiral galaxy NGC 4254"s dazzling swirls
NGC 4254, a spiral galaxy, is resplendent in orange and blue in this Jan. 29, 2024, image from the James Webb Space Telescope. This is one of 19 nearby spiral galaxies recently imaged by the telescope as part of the long-standing Physics at High Angu.....»»
Archaeologists discover oldest known bead in the Americas
University of Wyoming archaeology Professor Todd Surovell and his team of collaborators have discovered a tube-shaped bead made of bone that is about 12,940 years old. The bead, found at the La Prele Mammoth site in Converse County, is the oldest kno.....»»
Which came first: Black holes or galaxies?
Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data suggests......»»
Hubble spies baby stars being born amid chaos of interacting galaxies
Amid swirling gas and dust pulled by gravitational forces of interacting galaxies, there can be bursts of star formation, creating new generations of stars......»»
Hubble detects celestial "string of pearls" star clusters in galaxy collisions
When spectacular cosmic events such as galaxy collisions occur, it sets off a reaction to form new stars, and possibly new planets that otherwise would not have formed. The gravitational pull that forces the collisions between these galaxies creates.....»»
JWST data suggest exoplanet K2-18b may have molten surface rather than a watery ocean
A multi-institutional team of astronomers, Earth scientists and planetary physicists has found evidence, via data from the James Webb Space Telescope (JWST), that some hycean exoplanets may have molten surfaces rather than watery oceans. In their stu.....»»
Fossilized frog with belly full of eggs unearthed in China is oldest of its kind
An international team of Earth scientists, evolutionary biologists and paleontologists has unearthed an ancient frog with a belly full of eggs, the oldest known find of its kind. In their paper published in Proceedings of the Royal Society B, the gro.....»»
If plants can pick fungi to help fight pests and diseases, it opens a door to greener farming and ecosystem recovery
Just beneath your feet, an ancient and silent alliance endures. This alliance between plants and arbuscular mycorrhizal (AM) fungi is one of the oldest biological partnerships on Earth......»»
New findings from JWST: How black holes switched from creating to quenching stars
Astronomers have long sought to understand the early universe, and thanks to the James Webb Space Telescope (JWST), a critical piece of the puzzle has emerged. The telescope's infrared detecting "eyes" have spotted an array of small, red dots, identi.....»»
The 5 best telescopes for viewing planets and galaxies in 2024
Of all the objects that you can view through a telescope, some of the most stunning to behold are the planets in our solar system, and the galaxies that lie far beyond it. But if you want to see more distant and fainter objects, you’ll need a d.....»»
Our oldest microbial ancestors were way ahead of their time

Dark matter might help explain how supermassive black holes can merge
Although the exact nature of dark matter continues to elude astronomers, we have gained some understanding of its general physical properties. We know how it clusters around galaxies, how it makes up much of the matter in the universe, and even how i.....»»
Hubble captures a suspected galaxy encounter
UGC 3912 is classified as a spiral galaxy, but you wouldn't know it from this detailed NASA Hubble Space Telescope image. UGC 3912's distorted shape is typically indicative of a gravitational encounter with another galaxy. When galaxies interact—ei.....»»
Even early galaxies grew hand-in-hand with their supermassive black holes
Within almost every galaxy there is a supermassive black hole. This by itself implies some kind of formative connection between the two. We have also observed how gas and dust within a galaxy can drive the growth of galactic black holes, and how the.....»»
