Stages of Star Formation

This image, captured by NASA’s James Webb Space Telescope and released on June 5, 2026, shows just a small portion of one of the Orion Molecular Clouds, a long and massive filament of cold gas and dust beyond the Orion Nebula. Every stage of star formation — from the youngest stellar embryos to protoplanetary discs […]

Hubble Glimpses Merging Galaxy Clusters

This NASA Hubble Space Telescope image features a galaxy cluster, called CL0016+1609 or MACS J0018.5+1626, that is very bright at X-ray wavelengths and is one of the most extensively studied clusters at X-ray and radio wavelengths. The X-ray observations of this cluster revealed that it is two clusters merging along our line of sight.

Search for Hidden Cosmic Companions in Sun’s Backyard

Some stars have planets. Others are orbited by brown dwarfs, balls of gas too massive to be planets, but too low-mass to be stars. Astronomers love these brown dwarf-star pairs because being paired with a star helps reveal a brown dwarf’s age. Ages of astronomical objects are often hard to measure, but essential for understanding […]

NASA’s Fermi Mission Uncovers Possible Sibling Supernova Remnants

A new study of two supernova remnants, the debris left behind after stars explode, suggests the explosions came from stellar siblings that once orbited each other. The first star’s detonation sent its binary companion hurtling through space, and then, after traveling for thousands of years, the surviving star blew up too.

NASA’s Webb Catches Exoplanet Getting Roasted

That’s the latest from researchers analyzing NASA’s James Webb Space Telescope’s observations of HD 80606 b, an exoplanet four times the mass of Jupiter with an extremely elliptical orbit that sweeps close by its Sun-like star.
