Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole. Parallels in the physics of the universe and that of black holes have led ...

It’s the greatest cosmic murder mystery of the year: How did a black hole destroy a star—and what kind of black hole is the culprit? Normally, so-called “gamma ray bursts,” sudden flashes of extremely ...

An international team of astronomers, led by SRON, has observed a sudden outburst of matter near the supermassive black hole NGC 3783 at speeds reaching up to 20% of the speed of light. During a ...

Imagine you’re standing in front of a closed door. Behind it is a teenager’s bedroom, and your task is to rate how messy it is on a scale of 1 to 10. But here’s the twist: you can’t open the door – ...

Efforts to limit ozone-depleting chemical compounds had a significant impact. The ozone hole over the Antarctic is significantly smaller in 2025 than in previous years, ranking as the fifth-smallest ...

Astronomers have spotted the largest and most distant flare ever observed from a supermassive black hole. Nicknamed “Superman,” the flare originated 10 billion light-years from Earth, and at its peak, ...

Scientists have spotted the brightest flare yet from a supermassive black hole that shines with the light of 10 trillion suns. These bursts of light and energy can come from things like tangled-up ...

A supermassive black hole violently gobbled up an enormous star, producing a cosmic outburst with the light of 10 trillion suns, according to a new study. The black hole flare, as the phenomenon is ...

This gave the researchers an answer to a question that has been open for 40 years: whether black-hole pairs exist in the first place. "For the first time, we managed to get an image of two black holes ...

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 ...

To study the origins of our universe is to struggle with profound chicken-or-egg questions. We know the Big Bang happened. Cosmologists can see its afterglow in the sky. But no one knows whether the ...

Astronomers have detected a collision between two black holes in unprecedented detail, offering the clearest view yet into the nature of these cosmic oddities and confirming long-held predictions made ...
