Observations confirm that early-universe quasar neighborhoods are densely populated with companion galaxies
Quasars are the most luminous objects in the universe and are powered by material accreting onto supermassive black holes at the centers of galaxies......»»
Redwood Materials signs deal to recycle BMW’s EV batteries in the US
The automaker will use recycled materials from Redwood in its American-made EVs. Enlarge / BMW is moving to cylindrical cells for its sixth-generation EV powertrain, which debuts in the Neue Klasse. And now it has a recycling par.....»»
New cosmic distance catalog could unlock the mysteries of universe formation
A new catalog providing information on millions of distant galaxies, which determines their distances with unprecedented precision over a field of view and depth never before explored, has been published today......»»
Magnifying deep space through the "Carousel Lens"—rare alignment offers unique opportunity to study cosmology
In a rare and extraordinary discovery, researchers have identified a unique configuration of galaxies that form the most exquisitely aligned gravitational lens found to date. The Carousel Lens is a massive cluster-scale gravitational lens system that.....»»
James Webb image shows two galaxies in the process of colliding
A new image from the James Webb Space Telescope captures one of the universe's most dramatic events: the colliding of two galaxies......»»
Astronomers detect black hole "starving" its host galaxy to death
Astronomers have used the NASA/ESA James Webb Space Telescope to confirm that supermassive black holes can starve their host galaxies of the fuel they need to form new stars. The results are reported in the journal Nature Astronomy......»»
Combination and summary of ATLAS dark matter searches within 2HDM+a framework
In the 1930s, Swiss astronomer Fritz Zwicky observed that the velocities of galaxies in the Coma Cluster were too high to be maintained solely by the gravitational pull of luminous matter. He proposed the existence of some non-luminous matter within.....»»
New measurements reveal the enormous halos that shroud all galaxies in the universe
Have you ever wanted to make a $150,000 gamble? If you're right, you open a new window to the universe. But if you're wrong, you've just wasted a lot of money and time......»»
Hidden, compact galaxies in the distant universe—searching for the secrets behind the little red dots
Astronomers exploring the faraway universe with the James Webb Space Telescope, NASA's most powerful telescope, have found a class of galaxies that challenges even the most skillful creatures in mimicry—like the mimic octopus. This creature can imp.....»»
Massive merger: Study reveals evidence for origin of supermassive black hole at galaxy"s center
The origins of aptly named supermassive black holes—which can weigh in at more than a million times the mass of the sun and reside in the center of most galaxies—remain one of the great mysteries of the cosmos......»»
Deep imaging techniques reveal that galaxies are much much bigger than previously thought
If this galaxy is typical, then the study, published today in Nature Astronomy, indicates that our galaxy is already interacting with its closest neighbor, Andromeda......»»
James Webb spots another pair of galaxies forming a question mark
Webb has stumbled across a question mark-shaped galaxy, and the reasons for its uniqueness reveal how the telescope looks at some of the most distant galaxies......»»
James Webb is explaining the puzzle of some of the earliest galaxies
Webb has been causing bafflement in the field of cosmology. But the problem isn't that the universe is broken - it's that early black holes were playing tricks......»»
Hubble observes an oddly organized satellite galaxy
Andromeda III is one of at least 13 dwarf satellite galaxies in orbit around the Andromeda galaxy, or Messier 31, the Milky Way's closest grand spiral galactic neighbor. Andromeda III is a faint, spheroidal collection of old, reddish stars that appea.....»»
NASA"s Roman Space Telescope to investigate galactic fossils
The universe is a dynamic, ever-changing place where galaxies are dancing, merging together, and shifting appearance. Unfortunately, because these changes take millions or billions of years, telescopes can only provide snapshots, squeezed into a huma.....»»
Researchers start first low frequency search for alien technology in distant galaxies
The SETI Institute, the Berkeley SETI Research Center and the International Centre for Radio Astronomy Research announced a study using the Murchison Widefield Array (MWA) in Western Australia. Led by Dr. Chenoa Tremblay of the SETI Institute and Pro.....»»
Astrophysicists use AI to precisely calculate universe"s "settings"
The standard model of the universe relies on just six numbers. Using a new approach powered by artificial intelligence, researchers at the Flatiron Institute and their colleagues extracted information hidden in the distribution of galaxies to estimat.....»»
Hubble captures unique ultraviolet view of a spectacular star cluster
Roughly 210,000 light-years away, the Small Magellanic Cloud (SMC) is one of our Milky Way galaxy's closest neighbors. In fact, this small galaxy is one of the Milky Way's "satellite" galaxies, which orbit our home spiral galaxy......»»
Watch a star get destroyed by a supermassive black hole in the first simulation of its kind
Giant black holes in the centers of galaxies like our own Milky Way are known to occasionally munch on nearby stars......»»
New simulations shed light on stellar destruction by supermassive black holes
Monash University astronomers have contributed to a breakthrough in understanding the dramatic fate of stars that wander too close to supermassive black holes at the centers of galaxies......»»
