Solar System

The interiors of the solar system's ice giants, Neptune and Uranus, could experience an exotic form of precipitation, and these 'diamond rains' could be more common than previously thought.

NASA's venerable Voyager 1 spacecraft has reached a key milestone.

Here's how the Earth could theoretically leave the solar system.

Voyager 1 is once again beaming back clear telemetry data on its status beyond our solar system, solving one mystery and leading to another.

The spacecraft has since revealed a bizarre heliopause and a complex interstellar medium that's influenced by our sun.

A new study explores what happens when blown-up dying red giant stars engulf planets in their vicinity.

Lagrange found that the difference between an object's kinetic energy and potential energy unlocked something deeply profound about the universe.

Impressive infrared images of Jupiter's auroras were processed by citizen scientist Judy Schmidt.

The twin probes, launched in 1977, made groundbreaking discoveries about the solar system and inspired future space missions.

The Voyager missions are icons of cosmic exploration, and you can celebrate their 45th anniversary with a free webcast tonight (Aug. 18).

Ancient grains of dust that are older than the solar system itself have been found in samples from asteroid Ryugu brought to Earth by the Japanese Hayabusa2 spacecraft nearly two years ago.

Scientists using new computational methods have come up with a new insight into the potential workings of the complex atmosphere of Venus.

A new model exploring the dwarf planet Ceres suggests radioactivity deep in the small world may have created criss-crossed geology at its surface.

Voyager 1 and Voyager 2 continue their slow journeys deep into interstellar space.

The inner solar system spins much more slowly than modern physics would expect, and a new study may help to explain why.

NASA's Psyche asteroid mission is moving into a review after software testing issues forced an extended launch delay to at least July 2023. Its future remains uncertain.

In the next year, the James Webb Space Telescope will spend roughly 7% of its time focused not on distant galaxies, but on our own solar system. Here's a look at what it might see.
