On April 25 and 26, 2019, NSF’s Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European-based Virgo detector registered two new gravitational...
A spectacular new image from the NASA/ESA Hubble Space Telescope shows SPT-CL J0615-5746, a very massive group of galaxies located approximately 7.7 billion...
Professor Avi Loeb of the Harvard-Smithsonian Center for Astrophysics and colleagues have proposed a new test for inflation, the theory that our Universe...
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...
In 2018, a team of astronomers from the United States and Canada discovered that an ultra-diffuse galaxy called NGC 1052-DF2 (DF2 for short) contains virtually...
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...
A team of astronomers using the Gemini-South telescope has discovered one of the oldest stellar clusters in the Milky Way. The team’s results date the...
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...
About a third of the normal matter — meaning hydrogen, helium and other elements — created shortly after the Big Bang is not seen in the present-day...
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...
A team of astronomers from the Space Telescope Science Institute and the Institute for Astronomy at the University of Hawaii has released data from the...
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...
An international team of astrophysicists from the University of Surrey, Carnegie Mellon University and ETH Zürich has found evidence that dark matter...
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...
