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 ...

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 ...

In 2023, astronomers detected a huge collision. Two unprecedentedly massive black holes had crashed an estimated 7 billion light-years away. The enormous masses and extreme spins of the black holes ...

“These things are so great and have so many uses in so many areas that I don’t even have to market them. Customers just find me,” says Larry Schwartz, who’s been in the safety-pin business for more ...

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, ...

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 ...

Whenever someone talks about black holes, they almost always talk about the event horizon and the singularity. After all, that's what defines a black hole, right? Well, it depends on what you mean by ...

A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions. Scientists tracked the complete cosmic collision, confirming that black ...

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 ...
