The universe is vast, and while our solar system is the center of our everyday lives, it is just a tiny part of the cosmic expanse. Beyond our Sun lies a collection of stars that are our closest ...

The universe is vast, and even within a mere 50 light-years of Earth lies a stunning variety of stars that defy imagination. This relatively small region of our cosmic neighborhood hosts over 1,400 ...

Astronomers have discovered a low-mass "sub-Earth" planet orbiting the closest solo star to the solar system, Barnard's star, that has a year lasting just three Earth days.

The hungry black hole was spotted roughly 137 million light-years from Earth — or about 35 million times as far as Proxima Centauri, the closest star to the sun.

The nearest single star to the sun, Barnard’s star, has a brood of planets all its own. The red dwarf star, about six light-years from Earth, hosts four close-in planets each about two to three ...

Alpha Centauri is about 4.4 light-years (roughly 25 trillion miles, or 40 trillion kilometers) from Earth and is home to three separate stars. The closest star, Proxima Centauri, also hosts an ...

Astronomers have discovered that the closest black holes to Earth may exist in the Hyades star cluster. Observations made with the Gaia satellite suggest that several black holes likely exist in ...

Astronomers have discovered four planets that are just a fraction of the mass of Earth orbiting Barnard’s Star, which is 6 light-years from Earth.

A new study of super-fast-moving stars suggests that they were accelerated by a monster black hole that's been lurking unseen in the galaxy next door. This appears to be the closest supermassive ...

NASA's ISS-mounted X-ray telescope NICER has weighed and measured the closest pulsar to Earth. The neutron star PSR J0437 spins 174 times a second and has a mass of 1.4 suns.
