The Sun’s outermost atmosphere, the corona, seethes at temperatures above one million degrees. Yet draped across it are ...

This artist’s concept depicts the boundary of the sun’s atmosphere that marks the point of no return for material that escapes the sun’s magnetic grasp. Deep dives through this area using NASA’s ...

Astronomers have produced the first continuous, two-dimensional maps of the outer edge of the sun's atmosphere, a shifting, frothy boundary that marks where solar winds escape the sun's magnetic grasp ...

Diagram of the Sun’s interior and outer atmosphere, showing the core, radiative and convection zones — separated by the tachocline — and surface features such as sunspots, flares, the chromosphere and ...

The study may help predict dangerous solar storms and protect satellites and power grids.

The Sun’s outer atmosphere is far hotter than its surface — a long-standing mystery in solar science. A new study 1 suggests that the answer may lie in countless tiny eruptions happening all the time ...

Using data collected by NASA's Parker Solar Probe during its closest approach to the sun, a University of Arizona-led research team has measured the dynamics and ever-changing "shell" of hot gas from ...
