Until recently, a large black hole formed from a collapsed star was able to avoid detection from the prying eyes of our powerful telescopes – despite lurking nearby Earth and being 33 times the ...
The Milky Way has a big newfound black hole, and it lurks close to Earth! This sleeping giant was discovered with the European space telescope Gaia, which tracks the motion of billions of stars in ...
Distance: Roughly 1,560 light-years away, located in the constellation Ophiuchus. (For comparison, the nearest star to our Sun is only 4.24 light-years distant.) Detection Method: Gaia BH1 doesn't ...
A simulation showed black holes with masses between 100 and 10,000 times that of the sun could be born through a chaotic ...
Black holes generally come in two sizes: big and really big. As they are so dense, they are measured in terms of mass rather than size, and astronomers call these two groups of stellar mass black ...
NASA’s James Webb Space Telescope observed an unusually large and highly luminous galaxy at a record-breaking 290 million ...
Black holes are the darlings of science and science fiction. They were conceptualized as early as 1783 by English natural philosopher John Michell, who proposed “dark stars.” He envisioned ...
(Nanowerk News) By combining forefront X-ray observations with state-of-the-art supercomputer simulations of the buildup of galaxies over cosmic history, researchers have provided the best modeling to ...
Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ...
Joint research led by Michiko Fujii of The University of Tokyo demonstrated a possible formation mechanism of ...
Based on estimates of the black hole's mass, and that of the disrupted star, they were able to come up with an estimate for the black hole's spin -- less than 25 percent the speed of light.
Tiny 'supercharged' black holes born just after the Big Bang may have been brief companions to primordial black holes, dying ...
