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

The Earth's movement is primarily directed towards the star Lambda Herculis at an approximate speed of 45,000 mph (72,000 km/h). This velocity, while significant, would require approximately 5.5 ...

NASA researchers show that artificial intelligence can anticipate solar flare buildups by tracking subtle changes across the ...

Solar wind sounds poetic, but it's a very real and powerful phenomenon, connecting the Sun to every part of our solar system.

A NASA mission is underway to map the heliosphere, which is a huge protective bubble around the solar system that was created by the sun.

To better understand why the planets have variable compositions, we have to first understand the process of how stars form. While the composition of gas and dust in a precursor molecular cloud is ...

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

When NASA’s twin Voyager probes left Earth in 1977, they carried computers weaker than a hand calculator and a modest goal of touring the outer planets. No one seriously expected them to redraw the ...
