In 2007, astronomers discovered the Cosmic Horseshoe, a gravitationally lensed system of galaxies about 5.5 billion light-years away. The foreground galaxy's mass magnifies and distorts the image of a distant background galaxy ...
Using early data from the Dark Energy Spectroscopic Instrument (DESI), a team of scientists have compiled the largest sample ever of dwarf galaxies that host an actively feeding black hole, as well as the most extensive collection ...
Black holes have been fascinating subjects of study, not just because they are cosmic vacuum cleaners, but also as engines of immense power capable of extracting and redistributing energy on a staggering scale. These dark ...
In 1974, science fiction author Larry Niven wrote a murder mystery with an interesting premise: Could you kill a man with a tiny black hole? I won't spoil the story, though I'm willing to bet most people would argue the answer ...
The supermassive black hole at the center of the Milky Way appears to be having a party—and it is weird, wild and wonderful.
A team of top astronomers including Dr. William Alston, Senior Lecturer in Data Science at the University of Hertfordshire's Center of Astrophysics, has detected unprecedented periodic X-ray pulses from the supermassive black ...
Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as singularities, i.e., points where the laws of physics break down. Identifying how singularities are resolved ...
Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed. HVSs travel much faster than normal stars, and sometimes, they can exceed the galactic escape velocity. ...
Astronomers have taken a crucial step in showing that the most massive black holes in the universe can create their own meals. Data from NASA's Chandra X-ray Observatory and the Very Large Telescope (VLT) provide new evidence ...
In an article published in Physical Review Letters on Thursday, scientists carried out an innovative study testing the existence of mirror asymmetries in our universe by studying the handedness of the gravitational-wave emission ...
