Amazing images reveal new details in the sun's atmosphere

City-sized droplets and twisting streams of plasma have been picked up by incredibly detailed images of the sun’s corona, showing our star as we’ve never seen it before

The Sun viewed on 29 January 2025 in the extreme ultraviolet range by NASA's Solar Dynamics Observatory (SDO) spacecraft. A vast 500,000 mile-wide coronal hole has opened in the sun's atmosphere. The area measures over 62 times the diameter of Earth and is now shooting high-speed solar wind toward Earth. When such solar activity is directed at Earth, the resulting geomagnetic storms can potentially disrupt satellite operations, power grids, navigation systems, and radio communications. There may also be spectacular displays of aurora caused as the Earth's magnetosphere is disturbed by the solar wind. According to spaceweather.com, this wind is estimated to hit Earth by Friday (31 Jan), resulting in G1 geomagnetic storm conditions.

This illustration lays a depiction of the sun's magnetic fields over an image captured by NASA?s Solar Dynamics Observatory. The complex overlay of lines can teach scientists about the ways the sun's magnetism changes in response to the constant movement on and inside the sun.

Source of the sun’s magnetic field may hide right under its surface

Scientists have long thought the source of the sun's magnetic field sat deep within the star, but it may exist in a far more convenient spot for us to observe it
