NASA scientists studying the sun have detected an enormous group of darkened patches in the middle of the star that are visible from 92 million miles away on Earth.
The splotches, known as sunspots, may look like mere specks on the solar surface from here, but they can actually be the size of whole planets, with strong magnetic fields — thousands of times stronger than the Earth’s magnetic field. The spots appear dark because they’re much cooler than surrounding parts of the sun.
“If you have eclipse glasses and good vision, you might be able to see it without magnification,” the U.S. space agency said on X, formerly known as Twitter. NASA then promptly reminded people never to look directly at the sun without the correct solar filters.
A solar eclipse can cook your eyes. Here’s when to put the glasses on.
