A black hole ejected from its galaxy could trigger a burst of signals
A black hole expelled from the center of its galaxy after a merger could trigger several detectable phenomena around it. The scenario begins with two massive black holes coming together at the heart of a galaxy.
A supermassive black hole appears to be racing away from its galaxy at nearly 1,000 kilometers per second, leaving a 202,000-light-year trail of star formation behind it. Computer models indicate the

The nearest known black hole to Earth sits just 1,560 light-years away
The closest black hole yet confirmed to Earth is not some distant monster lurking at the galaxy’s heart — it sits a relatively modest 1,560 light-years away, in the direction of the constellation Ophiuchus.
In dark skies at night, distant starlight twinkles and speaks to vast cosmic histories almost as old as time itself. New data from instruments such as NASA's James Webb Space Telescope are helping astrophysicists probe deep cosmic mysteries,

This Star Whips Around the Milky Way’s Black Hole Faster and Closer Than Any Other Known Star
At 15,500 miles per second, it’s the fastest planet or star ever observed by science, but its true value is how close it is to our galaxy’s supermassive black hole.
The James Webb Space Telescope has identified the most promising candidate yet for a black hole star, lurking 660 million years after the Big Bang. The hypothetical entity, which shines 100 billion
Despite their depiction as massive monsters that simply suck in everything, including light, astronomers know black holes actually spin. And they spin really, really quickly. Determining just how quickly is key to understanding how they affect their ...
The newly discovered object looks like a star the size of our solar system, but produces 100 billion times more energy than any star.
A black hole star, shown here in an artist's rendition, exhibits characteristics of both stars and black holes. Jose-Luis Olivares/MIT It’s time to cue up some Chris Cornell and get in the mood, because astronomers may have found a real black hole sun.
Black hole winds from one quasar churn hot gas across 300,000 light-years, carrying the energy of billions of exploding stars.
Nearly every massive galaxy observed hosts a supermassive black hole at its center. NASA’s James Webb Space Telescope has discovered that some of these supermassive black holes may even be too big for the galaxy they’re found in, challenging ...
