The blazar BL Lacertae, a supermassive black hole surrounded by a bright disk and jets oriented toward Earth, provided scientists with a unique opportunity to answer a longstanding question: How are X-rays generated in extreme ...
Ever since general relativity pointed to the existence of black holes, the scientific community has been wary of one peculiar feature: the singularity at the center—a point, hidden behind the event horizon, where the laws ...
A scientist from Tokyo Metropolitan University has solved the longstanding problem of a "dissonance" in gravitational waves emitted by a black hole.
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered evidence that suggests the presence of a long-sought supermassive black hole at the heart of the nearby spiral galaxy Messier 83 (M83). This surprising ...
A team of astronomers at the Space Telescope Science Institute, working with one colleague from the University of St Andrews' Center for Exoplanet Science and another from the European Southern Observatory, has confirmed ...
Although we know that supermassive black holes (millions of times the mass of our sun) lurk at the center of most galaxies, their very nature makes them difficult to spot and study. In contrast to the popular idea of black ...
A Michigan State University researcher saw X-rays coming from a black hole using the NASA Chandra X-Ray Observatory telescope.
A team of physicists have discovered a new approach that redefines the conception of a black hole by mapping out their detailed structure, as shown in a research study recently published in Journal of High Energy Physics.
A black hole is a region of space where gravity is so strong that nothing, not even light, can escape. There are two main types of black hole; stellar mass and supermassive black holes, and they differ in size, formation, ...
One of the most powerful objects in the universe is a radio quasar—a spinning black hole spraying out highly energetic particles. Come too close to one, and you'd get sucked in by its gravitational pull, or burn up from the ...
