Solar Orbiter pieced together 200 ultraviolet images to show our star’s million-degree atmosphere in all its glory.

Solar Orbiter began routine science operations in 2021 and has since looped ever closer to the Sun, stealing bits of speed ...

"Most people just dismiss partial eclipses. But I wanted to go to this partial eclipse to try to get the corona — and I did ...

In an achievement that defies conventional wisdom among astronomers, a trio of eclipse chasers has captured what experts confirm is the first documented observation of the solar corona during a ...

The European Space Agency (ESA)'s Solar Orbiter mission has obtained a stunning high-res image of the sun's upper atmosphere.

As we move away from the Sun, these tubes gradually widen. However, this expansion of open field lines is much stronger in the upper solar corona, due to the disappearance with altitude of so-called ...

The mission's four small suitcase-sized spacecraft will act as a single virtual instrument 8,000 miles across to image the solar corona, the sun's outer atmosphere, as it transitions into the ...

This week was monumental for NASA’s Polarimeter to Unify the Corona and Heliosphere, or PUNCH mission. The four small satellites sent to low Earth orbit opened their eyes metaphorically for the ...

Scientists from Skolkovo Institute of Science and Technology in cooperation with foreign colleagues have discovered how coronal holes - giant magnetic windows in the solar corona - eject streams ...
