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...
