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 discover new almost dark galaxy
By analyzing deep optical imagery from the IAC Stripe 82 Legacy Project, an international team of astronomers has serendipitously discovered a new almost dark galaxy. The newfound galaxy, dubbed "Nube," has a very low surface brightness and is as mas.....»»
How close is too close to a kilonova?
Cataclysmic events happen in the universe all the time. Black hole mergers, supernovae, gamma-ray bursts, and a whole host of others. Most of them happen in distant galaxies, so they pose no threat to us. But there are a few that could affect life on.....»»
Astronomers carry out largest ever cosmological computer simulation
An international team of astronomers has carried out what is believed to be the largest ever cosmological computer simulation, tracking not only dark but also ordinary matter (such as planets, stars and galaxies), giving us a glimpse into how our uni.....»»
JWST looks at the debris disk around a white dwarf
Debris disks are quite common in the universe. Young stars have protoplanetary disks from which planets form. Black holes have accretion disks that are the source of the galactic jets. Supernova remnants can form a disk around neutron stars. So what.....»»
Two Neptune-sized exoplanets discovered with TESS
An international team of astronomers reports the detection of two new exoplanets orbiting a bright star known as TOI-5126, using NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound alien worlds are similar in size to the solar system's.....»»
Do we live in a computer simulation like in The Matrix? Proposed new law of physics backs up the idea
The simulated universe theory implies that our universe, with all its galaxies, planets and life forms, is a meticulously programmed computer simulation. In this scenario, the physical laws governing our reality are simply algorithms. The experiences.....»»
The oldest pieces of Baltic amber found on the Iberian Peninsula indicates imports began over 5,000 years ago
A team of scientists from the Universities of Granada and Cambridge, as well as the Government of Catalonia, have identified the oldest pieces of Baltic amber ever found on the Iberian Peninsula, revealing that this luxury material used in jewelry an.....»»
New map of space precisely measures nearly 400,000 nearby galaxies
Astronomers have created a detailed atlas of almost 400,000 galaxies in our cosmic neighborhood. The Siena Galaxy Atlas was compiled using data from NSF's NOIRLab telescopes, and is designed to be the preeminent digital galaxy atlas for large galaxie.....»»
More JWST observations are finding fewer early massive galaxies
There's a common pattern in science. We develop some new process or tool that allows us to gather all kinds of data we've never had before, the data threatens to overturn all we've assumed about some long-established theory, and then the dust settles.....»»
Many-Mirrored Galaxies Deepen Dark Matter Mystery
A surprisingly complex galaxy cluster suggests that in the search for dark matter, nothing is as simple as it seems.....»»
Artificial intelligence and clay tablets: Not yet a perfect match
: More and more articles are popping up about the possibilities offered by artificial intelligence for researching documents in the oldest scripts, from translating ancient texts, to filling in missing parts of clay tablets. But are we better off lea.....»»
Race to find world"s oldest mammal fossils led to academic warfare in the 1970s
The hunt for the world's most ancient mammals descended into academic warfare in the 1970s, researchers from the University of Bristol have discovered......»»
Astronomers discover M87"s jet is triggering novae
Everyone loves a good mystery, and astronomers have just uncovered a new one in a nearby supermassive galaxy called M87. Like most galaxies, M87 regularly plays host to a smattering of stellar explosions called novae, each the result of a star steali.....»»
New observations of flares from distant star could help in search for habitable planets
Astrophysicists have used the James Webb Space Telescope (JWST) to take a close look at a volatile star......»»
Can JWST tell the difference between an exoEarth and an exoVenus?
As of October 2023, astronomers have discovered 5,506 exoplanets orbiting other stars. That number is growing daily, and astronomers are hoping, among other things, to find Earth-like worlds. But will we know one when we see it? How might we be able.....»»
Further evidence points to footprints in New Mexico being the oldest sign of humans in Americas
New research confirms that fossil human footprints in New Mexico are likely the oldest direct evidence of human presence in the Americas, a finding that upends what many archaeologists thought they knew about when our ancestors arrived in the New Wor.....»»
Plot thickens in the hunt for a ninth planet
A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity originally developed to understand the rotation of galaxies.....»»
Oldest evidence of human cannibalism as a funerary practice
The remains of human bones with cutmarks, breaks and human chewing marks found across northern Europe show that some human groups living around 15,000 years ago were eating their dead not out of necessity, but as part of their culture......»»
Hubble records rare radio galaxy NGC 612
A striking orange and blue streak fills this new image from NASA's Hubble Space Telescope. Hubble's visible and infrared capabilities captured this edge-on view of lenticular galaxy NGC 612. Lenticular galaxies have a central bulge and disk much like.....»»
Bursts of star formation explain mysterious brightness at cosmic dawn
When scientists viewed the James Webb Space Telescope's (JWST) first images of the universe's earliest galaxies, they were shocked. The young galaxies appeared too bright, too massive and too mature to have formed so soon after the Big Bang. It would.....»»
