Learning more could be the key to solving the deepest mysteries of the universe. And astronomers may have just unlocked a ...

A tiny object half a universe away, a scar in a stream of stars circling the Milky Way, and an unusual star cluster in a nearby satellite galaxy may not seem related at first glance. Yet a new study ...

With the exception of black holes, neutron stars are the densest objects in the universe. As their name suggests, neutron stars are mainly made of neutrons. However, our knowledge about the matter ...

There are black holes that are too big to be born from the death of a star but aren’t quite supermassive either. There’s finally evidence for where those came from.

In the European Physical Journal Plus, Rafelski and two colleagues mathematically demonstrated that the existence of CUDOs (compact ultra dense objects) do not have dark matter, but are filled with ...

One of the most intriguing predictions of Einstein's general theory of relativity is the existence of black holes: astronomical objects with gravitational fields so strong that not even light can ...

Astronomers suspect that in the first second after the universe formed, the very first black holes also formed. These tiny though profoundly dense objects — think of an atom-sized particle wielding ...
