Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

The black hole at the Milky Way’s heart neither slumbers nor sleeps. Instead, the ring of plasma surrounding it flickers constantly, punctuated by superbright flares, observations show. Astronomers ...

A decade ago, scientists first detected ripples in the fabric of space-time, called gravitational waves, from the collision of two black holes. Now, thanks to improved technology and a bit of luck, a ...

It was a “light” meal for this star destroyer. A black hole ate its way into the record books after devouring a star and creating a celestial outburst that burned with the light of a trillion suns, ...

For more than two decades, radio astronomers have been hunting for a specific kind of needle in the Milky Way’s most chaotic ...

One researcher’s analysis of Webb Space Telescope images could indicate that we’re all stuck in a black hole, according to research published in the Monthly Notices of the Royal Astronomical Society. ...

Astronomers may have finally cracked one of the universe’s biggest mysteries: how black holes grew so enormous so fast after the Big Bang. New simulations show that early, chaotic galaxies created ...

According to Einstein’s theory of gravity, black holes have only a small handful of distinguishing characteristics. Quantum theory implies they may have more. Now an experimental search finds that any ...

Astronomers have spotted a rare, rule-breaking quasar in the early Universe that appears to be growing its central black hole at an astonishing pace. Observations show the black hole is devouring ...

An international team led by a researcher at the Chiba Institute of Technology has discovered an extremely rare phenomenon: a galaxy about 10 billion light-years away whose brightness dropped to ...
