Explainer: What are black holes?
Among the most extreme celestial bodies in the universe, black holes are dense, massive entities whose gravity can sometimes hold together an entire galaxy.

Sun’s nearest stellar neighbor may have Earth-like planet
A planet roughly the size of Earth orbits within the “Goldilocks” zone of the Proxima Centauri. Only 4.2 light-years away, this star is the one closest to our sun.

A new, nonexplosive source of black holes?
At least one black hole may have formed from the collapse of a cloud of gas, which is not the usual birthing scheme. This might even be how some of the earliest gargantuan black holes developed.
