The largest solar telescope on Earth produces the most detailed image of a sunspot we’ve ever seen

Scientists have just created the most striking and detailed image of one sunspot people have ever seen.

The image, taken on January 28th the Inouye Solar Telescope, shows magnetic structures as small as 20 kilometers on the surface of the sun, Thomas Rimmele, the associate director at NSF’s National Solar Observatory (NSO) said in a Statement of the National Science Foundation. The NSF built and operates the telescope that captured this photo, which was released Dec. 3. The solar telescope is the largest dedicated to observing the sun.
