For decades, physicists have searched for dark matter, the invisible substance thought to make up roughly 85% of all matter in the universe. Although its gravitational influence shapes galaxies and the large-scale structure ...
An international team led by researchers from the University of São Paulo (USP) in Brazil has developed an innovative method to identify stars that have consumed the planets around them. The technique detects variations in ...
Using NASA's Chandra X-ray Observatory, scientists have discovered a new class of objects behaving unlike any they have seen before. Astronomers suggest these newly spotted objects in other galaxies may help solve not one, ...
New observations of the composition of distant galaxies offer insights into the earliest phases of the universe and confirm decades of scientific understanding of the elements and particles produced by the Big Bang, according ...
Astronomers have found the first direct evidence that a wandering black hole can feed itself by dragging gas along in its wake as it moves through its galaxy. It's the first direct evidence of an accretion channel long predicted ...
Nearly every galaxy has a supermassive black hole. The few that don't have had theirs ejected during a galactic collision. That's because galaxies and their black holes have formed hand in hand. There is still some debate ...
An international team of astronomers has discovered the most distant progenitor to a galaxy supercluster ever. The discovery supports existing theories of how galaxy clusters evolve and reveals how they are connected to the ...
Intense, brief flashes of radio light called fast radio bursts (FRBs) travel across billions of light-years to reach Earth, passing through a fog of matter along the way. The bursts' origins are unclear but may originate ...
Active black holes are easy to detect. Their superheated accretion disks emit bright X-rays, and the jets streaming from their poles are easily seen at visible and radio wavelengths. But most stellar-mass black holes are ...
UK astronomers have uncovered new clues about the origin of 3I/ATLAS—only the third known object from beyond the solar system ever spotted. In a new paper published in Monthly Notices of the Royal Astronomical Society, researchers ...
