This jagged jumble of pixels may look like a rainbow-colored thunderbolt, but it’s actually a spectrum of light gathered by the Hubble Space Telescope that shows the swirling motion of gas and stars ...

Black holes like the one shown in this illustration can grow astonishingly massive by feeding on immense amounts of matter. But just how big can they get? In the early 1960s astronomers discovered a ...

A decade ago, the first gravitational waves confirmed that black holes collide. Telescopes soon revealed shadows of giants lurking at galaxy cores. The next frontier is stranger: tiny black holes from ...

There could be a 90 percent chance that in the next decade, astronomers will spot a deep space explosion that confirms several long-standing theories about black holes – and which releases a complete ...

Astronomers detected a black hole displaced nearly a kiloparsec from the center of a dwarf galaxy 230 million light-years away. Unlike most, it is actively feeding and producing radio jets, making it ...

The younger black hole, the product of a cataclysmic cosmic event known as a black hole merger, was first spotted in 2019. Now, about 6 years later, a team of international researchers led by the ...

A black hole unlike any seen before has been spotted in the early universe. It’s huge and appears to be essentially on its own, with few stars circling it. The object, which may represent a whole new ...

Gazing up at the stars at night, it’s easy to imagine that space goes on forever. But cosmologists know that the universe actually has limits. First, their best models indicate that space and time had ...

Newly reported gravitational waves rang out as clear as a bell. Spotted in January, these spacetime ripples are the clearest yet discovered, cutting through the background noise better than any ...

The highest energy neutrino ever detected from space may finally have an origin story. Mathematical analyses suggest that the ghost particle could’ve come from a theoretical object known as a ...
