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 ...

For observers on Earth, the sun appears as a bright, familiar disk—but what we see is only half the story. Like the moon, one half of the sun is permanently hidden from our direct view: the far side ...

An active region can grow on the Sun while remaining completely hidden from Earth. By the time rotation brings it into view, a magnetic-field model relying on Earth-facing observations may already be ...

The sun’s wispy upper atmosphere, called the corona, is an ever-changing jungle of sizzling plasma. But mapping the strength of the magnetic fields that largely control that behavior has proved ...
