New observations show that newly formed planets close to a star help shepherd dust and gas to create more planets farther out ...

Sure, we discovered Pluto and other dwarf planets beyond it ... The orientation of their orbits isn't as randomly distributed as we'd expect, which could be caused by the small gravitational ...

The dwarf planet Makemake, which chills out in the deep freeze of the outer Solar System, might be home to an ice volcano 1. Makemake is one of many icy worlds that orbit the Sun past Neptune.

In a few billion years, our Sun will die. It will first enter a red giant stage, swelling in size to perhaps the orbit of ...

NASA's TESS satellite has discovered a Neptune-sized exoplanet closely orbiting its host star. It's just the fourth object of ...

When observing very distant objects, such as dwarf planets located beyond Pluto, their orbits appear somewhat unexpected. They move in very large elliptical (oval-shaped) orbits and seem clustered ...

New research on Ceres reveals hidden organic materials, suggesting subsurface reservoirs and internal energy sources.

Surviving planets would need to stabilize their orbits, retain water-rich atmospheres, and avoid destruction during the red giant phase. Despite the odds, white dwarf planets offer a fascinating ...

New measurements from NASA's Juno probe have seemingly put to bed the possibility of a magma ocean beneath the surface of Io.
