Saturn pumps into space varying amounts of heat based on its seasons, which drives planet-wide storms, data from NASA's Cassini mission has revealed.

Astronomer Giovanni Cassini observed Jupiter's 'Permanent Spot' in 1665, but new research suggests it's a different vortex from today's Great Red Spot.

NASA's Perseverance rover spotted a bizarrely light-toned boulder on Mars, the likes of which have never been seen before.

A powerful solar storm in May 2024 created auroras on Mars and provided scientists with crucial information that could aid future crewed missions to the Red Planet.

Some experts believe that the solar system's hypothetical ninth planet could be just a few years away from being discovered. If this is the case, how long would it take for humans to send probes to the elusive world?

Astronomers have been scouring the outer solar system for signs of a hypothetical ninth planet for almost a decade, without success. However, we may finally be on the cusp of finding it, experts say.

Once thought impossible to exist, water frost found atop Mars' Tharsis region volcanoes could come in handy for future human exploration missions, new research suggests.

New research shows that the speed of sound on Mars varies considerably by location and temperature. The findings could help scientists understand sounds picked up by Martian rovers, as well as make future crewed ventures safer.

This pit crater making recent headlines may open into a larger cave that could provide a sheltered environment for both astronauts and hypothetical Martian life.
