A team of particle physicists from the University of Melbourne, the Australian National University, King’s College London and Fermi National Accelerator...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have captured a spectacular image of I Zwicky 18 (I Zw 18 for short), the archetypal extremely...
University of Ottawa’s Professor Rajendra Gupta challenges the current theoretical model for the composition of the Universe by showing that, in fact,...
The new map, dubbed Quaia, includes around 1,295,502 quasars from across the visible Universe and could help astronomers better understand the properties...
When you are trying to solve one of the biggest conundrums in cosmology, you should triple check your homework. The puzzle, called the Hubble Tension,...
Astronomers have proposed a new theory that explains why a puzzling population of white dwarf stars stopped cooling for at least eight billion years.
This...
GN-z11 is an exceptionally luminous galaxy that existed when our Universe was only 420 million years old, making it one of the earliest and most distant...
The reionization of the Universe occurred some 500 to 900 million years after the Big Bang. It represents the transformation of neutral hydrogen into ionized...
The black hole in the newly-discovered quasar SMSS J052915.80-435152.0 (hereafter called J0529-4351) accretes around one solar mass per day onto an existing...
The formation of galaxies by gradual hierarchical co-assembly of baryons and cold dark matter halos is a fundamental paradigm underpinning modern astrophysics...
New insights from the NASA/ESA/CSA James Webb Space Telescope upend theories of how black holes shape the cosmos, challenging classical understanding that...
Using the Mid-InfraRed Instrument (MIRI) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have captured a spectacular image of N79, a region...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected a small and vigorous black hole in GN-z11, an exceptionally luminous galaxy...
Intriguingly, the gamma-ray signal detected by NASA’s Fermi Gamma-ray Space Telescope is found in a similar direction and with a nearly identical magnitude...
A fast radio burst event called FRB 20220610A flashed in what seems like an unlikely place: a collection of at least seven galaxies that existed when the...
Neutron-star cores contain matter at the highest densities in our Universe. This highly compressed matter may undergo a phase transition where nuclear...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have observed a disk bending wave in BRI 1335-0417, the oldest known spiral galaxy...
