Astronomers using the James Webb telescope alongside Canada's CHIME telescope have pinpointed the origin of one of the brightest blasts of radio energy ever detected in Earth's skies.

A distant galaxy nicknamed "Cosmic Grapes" is bursting with massive star-forming clumps — far more than expected — offering fresh clues about how galaxies grew in the early universe.

Astronomers using the James Webb telescope have zoomed in on a 'Little Red Dot' that existed just 500 million years after the Big Bang, and found that it may contain the earliest known black hole in the universe.

Alpha Centauri may have a "disappearing planet', new James Webb Space Telescope observations hint. If confirmed, it could be the closest alien planet to Earth that orbits in its star's habitable zone.

High-speed winds on exoplanet WASP-17b may align quartz crystals in its atmosphere and create dazzling light effects like "sun dogs."

Using data from the James Webb Space Telescope, astronomers have discovered dormant galaxies with a wide range of masses in the first billion years after the Big Bang, moving one step closer to understanding how early galaxies grow.

Astronomers have been given the rare opportunity to study an extrasolar object after the recent discovery of the interstellar comet 3I/ATLAS. Experts tell Live Science how they are planning to observe the cosmic visitor.

Located billions of light-years away, the "Cosmic Owl" is a pair of colliding ring galaxies spotted by the JWST. It's also an "exceptional natural laboratory" for studying how galaxies evolve.

This unprecedented view of the Bullet Cluster provided by the James Webb Space Telescope and the Chandra X-ray Observatory reveals how the dark matter is distributed.
