The planet is experiencing the most powerful solar event since 2003—and it's bringing spectacular Northern Lights.

Astronomers have long sought evidence to explain why comets at the outskirts of our own solar system contain crystalline ...

NASA’s newly launched IMAP mission is set to tell us more about the boundary between our Solar System and interstellar space ...

The sun’s rhythmic rise and fall in the sky can make it easy to forget that our star is unpredictable—a roiling, burbling mass of magnetically knotted plasma that governs the entire solar system. The ...

Solar Orbiter has captured the clearest evidence yet that a solar flare grows through a cascading “magnetic avalanche.” Small, weak magnetic disturbances rapidly multiplied, triggering stronger and ...

3I/ATLAS is the third interstellar visitor ever to visit the solar system having been formed around a distant star. Tune in ...

A powerful flare unleashed a severe solar storm that caused auroras and GPS disruptions on Earth.

A rare discovery beyond Neptune is forcing scientists to rethink early solar system dynamics and the forces that shaped ...

Our Sun’s outer atmosphere, the corona, is millions of degrees hotter than it should be, and no one knows why.

Scientists have developed a way to generate tiny amounts of solar energy at night. It’s true potential could be in space.

Unlike earlier studies, which often examined chemistry and atmospheric motion separately, the new simulations combined both.

Comet C/2025 R3 (PanSTARRS) might be the brightest comet of the year, scientists predict.
