Super spirals are the most massive star-forming disk galaxies in the Universe. They are much larger, brighter, and more massive than our own Milky Way...
Our Milky Way Galaxy is orbited by more than 50 companion galaxies. According to new research led by University of California, Riverside astronomers, several...
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...
