Physicists report a new measurement of the muon magnetic anomaly using data collected in 2019 and 2020 by the Muon g-2 experiment at Fermilab National...
Earendel, the farthest known star, is a massive B-type star more than twice as hot as our Sun, and about a million times more luminous, according to an...
Euclid, built and operated by ESA, with contributions from NASA, will observe billions of galaxies out to 10 billion light-years to create the largest,...
In the eleven years since its discovery, studies of the Higgs boson have become a central avenue for shedding light on the fundamental structure of the...
The dynamically relaxed galaxy cluster SPT-CL J2215-3537 is about 8.4 billion light-years from Earth, making it the farthest galaxy cluster ever spotted...
The Search for Extraterrestrial Intelligence (SETI) aims to answer one of the most important scientific questions: are we alone in the Universe? Complementing...
The first generation of stars in the Universe is yet to be observed. There are two leading theories for those objects: hydrogen burning Population III...
The Universe could be twice as old as current estimates, according to new research from the University of Ottawa that challenges the dominant cosmological...
Harvard University’s Professor Avi Loeb and colleagues have discovered at least 50 tiny spherical iron fragments near the fireball path of the first...
Astronomers using the NASA/ESA / CSA James Webb Space Telescope have discovered an active supermassive black hole in CEERS 1019, a galaxy that existed...
Galaxies are strung along filaments in the vast cosmic web, which also contains enormous voids. Using the NASA/ESA/CSA James Webb Space Telescope, astronomers...
A fundamental consequence of the relativistic picture of expanding space is cosmological time dilation, where events in the distant Universe appear to...
The Euclid spacecraft, built and operated by ESA, with contributions from NASA, lifted off from Cape Canaveral Space Force Station in Florida at 11:12...
Observations of high-energy astrophysical neutrinos have shown that they mostly originate from extragalactic sources such as active galaxies. However,...
Astrophysicists from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Collaboration have found evidence for gravitational waves...
Unlike most gamma-ray bursts, which are caused by exploding massive stars or the chance mergers of neutron stars, a long gamma-ray burst event dubbed GRB...
New research from the University of Toronto suggests that the so-called clumpiness problem, which centers on the unexpectedly even distribution of matter...
Only a few hundred million years after the Big Bang, the infant Universe was brimming with opaque hydrogen gas that trapped light at some wavelengths from...
Early Universe’s stars had up to several hundred solar masses. The earliest stars of 140-260 solar masses became pair-instability supernovae (PISNe)....
The newly-discovered black hole resides in the hyperluminous galaxy GN-z11 at a redshift of 11 and could have originated from a stellar mass seed at redshifts...
