Looking at all the stars in the night sky, you’d never notice that one of them wasn’t from around here. Astronomers have now found that a star right near the supermassive black hole at the center of the Milky Way likely originated in a smaller galaxy t… Continue reading Ancient extragalactic star discovered at the heart of the Milky Way
Astronomers have discovered evidence of a theorized type of black hole lurking in the distant universe. Known as an “Outsize Black Hole,” this object could help explain some fundamental cosmic mysteries, including how supermassive monsters form.Continu… Continue reading Evidence of theorized type of black hole discovered near dawn of time
The very fabric of spacetime is constantly warping, on unimaginably tiny scales, as ripples from past cataclysms wash over us. Astrophysicists have now detected a background sea of gravitational waves, using a galaxy-scale detector made up of dead star… Continue reading Galactic-scale detector picks up background distortions in spacetime
At the heart of our galaxy lurks a supermassive monster, which is currently slumbering – but it hasn’t always been so quiet. New observations reveal an X-ray “echo” from a time when the Milky Way’s central black hole awoke just 200 years ago, shining a… Continue reading X-ray echoes reveal recent bright flash from Milky Way’s black hole
Decades ago the astronomy world was taken aback by the discovery of strange vertical filaments of light spiking out from our galaxy’s central black hole. Now, the astronomer responsible for that finding has spotted more filaments, only these are orient… Continue reading Milky Way’s center found to be strung with more mysterious filaments
Astronomers have captured the biggest cosmic explosion ever detected. About 100 times bigger than the solar system and two trillion times brighter than the Sun at its peak, the mysterious miasma has remained visible for three years.Continue ReadingCate… Continue reading Biggest cosmic explosion ever seen: 100x the width of our solar system
Astronomers have detected a supermassive black hole ripping a passing star to shreds. Not only was this cataclysm closer to Earth than ever seen before, but its location and light emissions were unusual, hinting at a large unseen population of these ev… Continue reading Astronomers spot nearest star-destroying black hole
In 2019 we got the first-ever direct image of a black hole, which resembled a fuzzy, orange donut. Now, the team has refined the iconic image with the help of machine learning algorithms to produce the highest resolution image possible with the origina… Continue reading Algorithm makeover produces highest resolution image of black hole
Astronomers have spotted a bizarre sight out in the cosmos unlike anything they’ve ever seen before. A supermassive black hole has been ejected from its host galaxy, leaving a streak of light almost twice as wide as the Milky Way in its wake as the sho… Continue reading “Runaway” supermassive black hole creates new stars in its wake
NASA has confirmed that on October 9, 2022, our solar system was struck by a gamma-ray burst originating 1,900 light years away that was brighter than any since the beginning of human civilization, in what the space agency calls a “1 in 10,000 year” ev… Continue reading Earth hit by brightest gamma-ray burst on record in 1-in-10,000-year event
