A massive filament of gas and dust, designated X7, has been elongated during its long approach to the Milky Way galaxy's supermassive black hole Sagittarius A*. See W.M. Keck Observatory imagery of X7 ...
This black hole merger animation was created using data collected by the LIGO and Virgo gravitational wave detectors, an ...
A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity ...
An animation of a star that collapsed, forming a black hole. The black hole is at the center, unseen. Surrounding it is a dust shell moving away from the black hole and gas being pulled toward it.
A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...
Some evidence of supermassive black holes influencing the gas around them has previously been seen in X-ray images. However, ...
Supermassive black hole binaries form naturally when galaxies merge, but scientists have only confidently observed a very few of these systems that are widely separated. Black hole binaries that ...
In my January 23, 2026, “The Universe” column, I wrote about some of the biggest bangs the universe has to offer: exploding stars, hiccupping magnetars, stellar disruptions and colliding black holes.
