The familiar concept of a planetary core, a small, dense metallic heart we take for granted, may be the exception rather than the rule for exoplanets.

NASA’s TESS has released its most complete view of the starry sky to date
A recently developed ultra-black coating not only efficiently absorbs light, but is also extremely thin and durable, enabling its potential use on starshades that could someday support the imaging of exoplanets and potentially facilitate the detection of life beyond our solar system.
The Milky Way’s galactic bulge, the bulbous region that surrounds the galactic center, contains a dense collection of stars, planets, and other free-floating objects. This region has been studied for decades with numerous ground-based and space-based telescopes, including NASA’s Hubble and James Webb space telescopes. Soon, NASA’s Nancy Grace Roman Space Telescope will be the […]
By probing the atmosphere of a mini-Neptune exoplanet, the James Webb Space Telescope has found that it formed much farther from its star than it is today, possibly explaining the origin of many other mini-Neptunes in the …
New simulations suggest binary star systems may be ideal for planet formation, and may produce more gas giants than single-star systems.
…
“Most planetary systems appear as ‘peas in a pod.’ This is not the case in the TOI-201 system.”
NASA is aiming for an early September 2026 launch of the Roman Space Telescope, a powerful new observatory that could transform astronomy with massive infrared sky surveys, huge data returns, and faster follow-up discoveries.
