Understanding the early universe is a foundational goal in space science. We're driven to understand nature and how it ...

Since its launch in late 2021, the James Webb Space Telescope (JWST) has been glimpsing some of the earliest epochs of cosmic ...

"If there are lots of black holes out there, some of them must surely pass through our backyard every now and then." ...

BUFFALO, N.Y. — Imagine the formation of a black hole and you’ll probably envision a massive star running out of fuel and collapsing in on itself. Yet the chaotic conditions of the early universe may ...

"Primordial black holes should form during the first few seconds after the Big Bang. If they exist, they have some advantages over astrophysical black holes," Regan said.

Tiny ‘primordial’ black holes created in the Big Bang may have rapidly grown to supermassive sizes Did 'primordial' black holes born right after the Big Bang help our universe's 1st stars form?

Primordial black holes could be a type of dark matter called MACHOs, which stands for massive compact halo objects, because astronomers think they’re found in the halos, or outskirts, of galaxies.

Massive primordial black holes could be the long sought answer. Such large, heavy objects might also have served as the anchors around which early galaxies coalesced, another conundrum that has ...

However, the paper’s new modeling suggests that even planets with their original primordial atmospheres of hydrogen and helium (something Earth also once had) can be potentially habitable for ...

The search for primordial stuff—rocks that have survived 4.5 billion years since the formation of the Earth without being changed by forces that shook and scrambled our planet—is one of geology's long ...
