Black Hole

What's happening For the first time, astronomers have used a quirk of gravity's effect on starlight to spot a "free-floating" black hole. Why it matters Until now, the only way to spy on the mysterious cosmic objects was by looking for the light reflected by matter on a black hole's…

Another day, another black hole mystery! While we may not understand the elusive time-bending structures completely, it's exciting to be alive in times when you hear the word "black hole" multiple times a day. Now, a black hole situated in a far-off galaxy's centre has been spotted sending radio emissions…

Astronomers at the Event Horizon Telescope (EHT) revealed this image of supermassive black hole Sagittarius A* in May. Photo / National Science Foundation Scientists are hoping to launch telescopes into space "in 10 to 15 years" to take time-lapse videos of black holes, an expert has said. The videos will…

Sather Gate, the iconic entrance gate to the campus of UC Berkeley in downtown Berkeley, Calif. Smith Collection/Gado/Getty Images A UC Berkeley research team led by graduate student Casey Lam and astronomy associate professor Jessica Lu may have discovered the first “free-floating” black hole, Science Daily reported.  According to the…

An artist’s impression of two black holes about to collide and merge. Gravitational waves are ripples in the curvature of spacetime caused by accelerated masses that propagate as waves at the speed of light outward from their source. Although you don’t need a gigantic object to create gravitation waves, our…

Elena11/Shutterstock Black holes have made a number of big headlines over the last few years. In 2019, the aptly named Event Horizon Telescope (EHT) managed to capture one on film for the first time. And in May of 2022, the EHT snapped a pic of Sagittarius A*, the supermassive black…

By using a technique called gravitational microlensing, a team of astronomers from the University of California, Berkeley, has discovered a ‘dark’ free-floating black hole in the Milky Way galaxy. This was the first time they found a free-floating black hole by observing the brightening of a more distant star as…

A blazar is a feeding supermassive black hole (SMBH) in the heart of a distant galaxy that produces a high-energy jet viewed face-on from Earth. They are among the most luminous and energetic objects in the Universe and are composed of ionized matter traveling at nearly the speed of light.…

This is an illustration of a close-up look at a black hole drifting through our Milky Way galaxy. ... The black hole distorts the space around it, which warps images of background stars lined up almost directly behind it. FECYT, IAC For the first time ever, astronomers using NASA’s Hubble…
