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 ...

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

Solar flares have an enormous impact on the wider Solar System. These sudden releases of energy can cause geomagnetic storms on Earth and radio blackouts too, like the one that's happened in the last ...

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

How big it is: 865,000 miles (1.392 million kilometers) across How far away it is: 93 million miles (150 million km) What type of star it is: A yellow dwarf star The sun is the star at the center of ...

On its closest-ever flyby to the sun, NASA's Parker Solar Probe captured newly released images of solar winds purging out from the sun's outermost atmosphere, the Corona. Scientists are learning more ...

Interstellar comet 3I-ATLAS is a rare cosmic visitor that may be older than our Sun, offering scientists a unique glimpse into the early Milky Way. Its ancient origins and unusual composition could ...

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

At times, the sun ejects energetic material into space, which can have consequences for space-based and even ground-based ...

LONDON (APTN/CBS Newspath/WKRC) - Scientists have discovered particles older than our solar system in a sample from the asteroid Bennu, brought back to Earth by NASA's OSIRIS-Rex spacecraft. The ...
