Wanted: Exoplanets With a Flair for Drama

This artist’s concept shows what a thick atmosphere above a vast magma ocean on exoplanet TOI-561 b could look like. Measurements of light captured from the planet’s dayside by NASA's James Webb Space Telescope suggest that in spite of the intense radiation it receives from its star, TOI-561 b is not a bare rock.

Fast-moving asteroid found in Sun’s glare

NASA’s Perseverance rover discovered “leopard spots” on a reddish rock nicknamed “Cheyava Falls” in Mars’ Jezero Crater in July 2024. Scientists think the spots may indicate that, billions of years ago, the chemical reactions in this rock could have supported microbial life; other explanations are being considered.

How Do We Define an 'Earth-Like' Planet?

This artist's concept is based on Hubble Space Telescope images of gas-and-dust disks around the young star TW Hydrae. Hubble Space Telescope photos show shadows sweeping across the disks encircling the system. Credit: NASA, AURA/STScI for ESA, Leah Hustak (STScI).
