A bizarre 'ultraluminous X-ray source' shines millions of times brighter than the sun, breaking a physical law called the Eddington limit, a new study finds.

Astronomers using the James Webb Space Telescope have detected the four oldest galaxies in the known universe, which are forming stars much faster than thought possible.

Earth's magnetic field protects life on our blue planet — and astronomers just found evidence of a magnetic field on a rocky exoplanet 12 light-years away.

NASA's James Webb Space Telescope measured the temperature of the Earth-like planet TRAPPIST-1b and found that it is too hot for humans and likely has no atmosphere.

An object once thought to be a radio galaxy is actually an active black hole that changed angles to point directly at Earth, new research suggests.

Alien life could thrive in terminator zones, the edges between the light and dark sides of planets that are tidally locked with their host stars.

Simulations show that collisions between moons and planets may be a regular danger for possible extraterrestrial life.

NASA astronomers used the Hubble Space Telescope to measure the mass of a white dwarf, an important step for understanding how stars die.

Mysterious fast radio bursts (FRBs) helped astronomers weigh our galaxy, and reveal that some matter is missing.
