NASA’s Solar Dynamics Observatory satellite took a picture where the holes in the Sun’s corona form a pattern familiar to the human eye.
Nasa shared a special shot of the center of our solar system: in the image of the Solar Dynamics Observatory satellite, the regions known as the holes in the Sun’s corona form a “smile” on the surface of the star.
The dark areas visible in the ultraviolet photo are gaps in the Sun’s corona, which is the Sun’s outer gas ring. The holes in the corona are temporary, areas cooler than the rest of the corona with a temperature of about a million degrees, from which the fast solar wind pushes out into space.
NASA’s Solar Dynamics Observatory satellite studies, among other things, the structure of the Sun’s magnetic field through the holes in the corona. In addition, it monitors the solar wind going into space.
The Guardian’s story (you’re moving to another service) according to us, a smile can have mischievous effects: the solar wind coming out of the openings can mean a solar storm for Saturday.
Finnish Meteorological Institute’s space weather (you switch to another service) according to the magnetic activity has been slightly elevated during Saturday, but still does not exceed the threshold value for the probability of, for example, the aurora borealis.
