Planet orbiting 2 stars discovered by TESS

NASA's TESS mission has just found its first planet orbiting 2 stars. It's a Jupiter-sized world that takes less than an Earth-year to complete one orbit.

Piece of the moon? Asteroid might have lunar origin

Astronomers at the University of Arizona say that a peculiar near-Earth asteroid may actually be a lost piece of the moon that broke off in the ancient past.

Weird rocky exoplanets unlike any seen before

Astronomers say they have evidence for weird rocky exoplanets that are unlike any in our own solar system, based on the chemical analysis of white dwarf stars.

Revealing hidden alien oceans, with chemistry

NASA scientists say that to find hidden alien oceans on distant exoplanets, use chemistry. Ocean worlds will have distinctly different atmospheric compositions from planets that don't have oceans, including a lack of ammonia.

Exoplanet lost its atmosphere in ancient impact

A young Earth-sized exoplanet lost its atmosphere in a giant impact about 200,000 years ago, leaving behind clues in leftover dust and carbon monoxide gas.

A new field guide for hot Jupiters

A new field guide for hot Jupiters combines Hubble Space Telescope observations with theoretical models. It should inform ideas about planet formation.

Asteroid Bennu’s boulder mystery solved

Asteroid Bennu's boulder mystery has now been solved, scientists say. Highly porous rocks explain the abundant large rocks but lack of fine sand-like regolith.

See 42 of the largest asteroids in new images

Astronomers with the European Southern Observatory (ESO) have obtained new and more detailed images of 42 of the largest asteroids in the main asteroid belt.

Moon-forming disk around super-Jupiter exoplanet?

Astronomers say that there may be moons being created in a moon-forming disk of dust around a giant super-Jupiter planet (or brown dwarf) 500 light-years away.
