In a paper published in the journal Physical Review Letters, an international team of physicists proposes a new strategy for searching for hypothetical...
Dark matter, the mysterious substance that makes up roughly a quarter of the Universe, may have its origin in pre-Big-Bang times, according to a new paper...
According to new research led by Rochester Institute of Technology (RIT), the collision of the recently-discovered dwarf galaxy Antlia 2 with our Milky...
Professor John Terning and Dr. Christopher Verhaaren from the University of California, Davis, have a new candidate for dark matter — a dark monopole...
Markarian 1216 (Mrk 1216 for short) is a compact elliptical galaxy about 316 million light-years away. New data from NASA’s Chandra X-ray Observatory...
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 less than 1 billion years old, some of its stars turned into supermassive black holes. A key mystery in astronomy has been: why are...
An international team of astrophysicists from the University of Surrey, Carnegie Mellon University and ETH Zürich has found evidence that dark matter...
Dark matter is a mysterious substance that makes up about 85% of the matter in the Universe. It does not emit any kind of electromagnetic radiation and...
The standard cosmological model known as LambdaCDM can only explain 5% of the observable Universe. The remaining 95% is famously made up almost entirely...
A duo of astrophysicists is proposing a new model for the invisible material that makes up most of the Universe: it’s possible that a small fraction...
A blue supergiant star nicknamed Icarus is so far away that its light has taken 9 billion years to reach our planet. It appears to us as it did when the...
An international group of researchers has discovered that an anomalous gamma-ray signal from Milky Way’s center comes from 10 billion-year-old stars,...
Several dwarf galaxies orbiting around a nearby elliptical galaxy called Centaurus A are rotating in synchrony around their host, to astronomers’ surprise....
In 2014, a team of astrophysicists reported the detection of an unusual emission line in X-ray light from the Perseus cluster, a cluster of galaxies 240...
New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) push back the epoch of massive-galaxy formation even further by identifying...
Based on the combination of data taken 12 years apart by the NASA/ESA Hubble Space Telescope and ESA’s Gaia mission, astronomers have pinned down for...
Astrophysicists using the High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory in Mexico have detected the extended emission of high-energy gamma...
