The Solar System's largest moon could be a dark matter detector, according to a new paper. All we have to do is look. As far ...

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

Instead, they say that if primordial black holes exist and make up most of dark matter, "then one must travel through the inner solar system every one to 10 years." ...

"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.

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

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 ...

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.

But interest in primordial black holes waned over the decades as searches for them turned up empty — that is, until we had the Laser Interferometer Gravitational-Wave Observatory (LIGO).
