NASA’s SPHEREx space telescope has observed interstellar comet 3I/ATLAS flaring dramatically months after its closest pass by ...

NASA is facing a race against time to save its 21-year-old spacecraft, the Neil Gehrels Swift Observatory, which has been on a critical mission to study some of the most powerful explosions in the ...

Recent observations suggest that 'runaway' black holes are tumbling through the cosmos. Building on decades of theory, the discovery adds a remarkable new chapter to the story of the universe.

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.

The earliest black holes in the universe may not have disappeared from Hawking radiation after all, new research hints. Instead, they fed on the energy of the ancient cosmos to grow supermassive.

Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...

In 2023, a cosmic neutrino detector called KM3NeT spied an event so powerful that it challenged existing models of astronomy. The detection, captured in the waters of the Mediterranean Sea, seemed to ...

A supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole ...

Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields ...
