While Titan could possibly harbor simple, microscopic life, it likely could support only a few pounds of biomass overall, research finds.

"It is only in recent years that we have begun to realize that planets are more complex than we had thought."

A steady diet of smaller storms may be what fuels Jupiter’s Great Red Spot—and a decline in small storms may be causing it to shrink.

“This is the first time we have ever seen a hint of an atmosphere on a habitable zone rocky or ice-rich exoplanet."

A rocky planet with a large moon may have good potential to host life, given that the moon controls essential aspects for life on Earth.

A planet that should have been stripped to bare rock by its nearby host star's intense radiation somehow grew a puffy atmosphere instead.

For the first time, researchers have found frost on Mars' Tharsis volcanoes, challenging previous assumptions about the planet's climate.

New research offers a peek at the ocean that likely covers Pluto under a shell of nitrogen, methane, and water ice.

A large heart-shaped structure non the dwarf planet Pluto has puzzled scientists for years. Now they may have some answers.

"With unprecedented glimpses into these disks surrounding young stars, the birthplaces of planets, JWST helps us uncover how planets form."
