Measurements of today’s expansion rate do not match the rate that was expected based on how the Universe appeared shortly after the Big Bang over 13...
When the Universe was still very young, only a few kinds of atoms existed. Astrophysicists believe that around 100,000 years after the Big Bang, ionized...
Astronomers using the Subaru Telescope have discovered 83 quasars in the distant Universe, from a time when the Universe was less than 10% of its present...
A duo of astronomers has spotted three new globular clusters in the Milky Way’s bulge, a 10,000-light-year-wide central structure made primarily of old...
Astronomers using data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton spacecraft have found evidence that an invisible force called dark...
When the Universe was less than 1 billion years old, some of its stars turned into supermassive black holes. A key mystery in astronomy has been: why are...
Astronomers using the NASA/ESA Hubble Space Telescope have spotted the brightest quasar ever seen in the early Universe.
Less than a billion years after...
According to a Swinburne University of Technology-led study, the newly-discovered relic cloud of gas is unpolluted by stars even 1.5 billion years after...
Physicists from the PHENIX Collaboration have created droplets of a liquid-like state of matter called quark-gluon plasma, forming three distinct shapes...
Astronomers believe that our Universe began forming the first stars when it was a few hundred million years old. Since then, the Universe has become a...
WISE J224607.55-052634.9 (W2246-0526 for short), the most luminous galaxy ever discovered, is accreting (eating) at least three of its smaller neighbors,...
SDSS J0915+3826, a giant group of galaxies located approximately 4 billion light-years away, is so massive that its gravity bends light like a lens, making...
Astronomers using ESO’s Very Large Telescope have spotted a gigantic galaxy proto-supercluster in the early Universe, just 2.3 billion years after the...
Physicists from the ALICE (A Large Ion Collider Experiment) Collaboration at CERN have gained new insights into the properties of the quark-gluon plasma,...
Astronomers using the Multi Unit Spectroscopic Explorer (MUSE) instrument on ESO’s Very Large Telescope have discovered an unexpected abundance of Lyman-alpha...
Astronomers using the NASA/ESA Hubble Space Telescope have captured a spectacular image of Abell 370, a massive galaxy cluster embedded among nearly thousands...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected a powerful ‘wind’ in SPT-S J231921-5557.9 (SPT2319-55 for short),...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), a team of astronomers revealed that molecular clouds in a galaxy called AzTEC/COSMOS-1,...
A team of astronomers from the United States and the United Kingdom has found evidence that Milky Way’s faintest satellites — including dwarf galaxies...
