The Latest Breaking News from Solar System

The long-sought evidence of alien life could be lurking in Earth's oceans, says Harvard astrophysicist Avi Loeb. Here is his plan to find it.

NASA's most distant spacecraft had a critical thruster problem far from home. Fixing it required a long-distance call to overcome extreme cold and dwindling power.

Was Ceres born in the main asteroid belt, or did it migrate there from the outer solar system? The answer is buried in data from NASA's Dawn spacecraft.

A long-lost moon could explain why Mars is so different from the other rocky planets in the solar system.

The Very Large Telescope in northern Chile imaged a "super-Jupiter" exoplanet called 2M1207b, precisely 20 years ago this week. This was the first direct visual confirmation of a world beyond our solar system.

New simulations show that Jupiter's massive moon Ganymede was knocked off its axis when it was struck by a roughly 90-mile-wide asteroid around 4 billion years ago. The colossal collision was likely one of the biggest asteroid impacts the solar system has ever seen.

Scientists discover potential evidence of two Kuiper Belts in the outer Solar System, hinting at a breakthrough in planetary formation studies.

Impact may have caused largest moon in solar system to swing on its axis, say scientists

A network of citizen scientists recently found a "warm" Jupiter 300 light-years from Earth that can reveal clues about how our own Jupiter and solar system evolved.

From the moment of the Big Bang, everything in the universe has kept moving, but why is that?

Our Sun drives a constant outward flow of plasma, or ionized gas, called the solar wind, which envelops our solar system. Outside of Earth’s protective magnetosphere, the fastest solar wind rushes by at speeds of over 310 miles (500 kilometers) per second. But researchers haven’t been able to figure out…
