there she was Sun but in a very good mood. In addition to its usual brilliance, the earthly celestial body put on a slightly mischievous smile.
At least that’s what this spectacular satellite image published by NASA on Twitter suggests. “Say cheese!” the space agency headlined, adding: “Today, the Solar Dynamics Observatory caught the sun ‘smiling’.”
But in fact, with the dark spots, it only seems so, space experts clarify. Why: The dark spots on the sun are called coronal holes. Two of these coronal holes look like twinkling eyes in the image, while the third looks like a wide, smiling mouth.
According to NASA, coronal holes are only visible in ultraviolet light and mark regions where the fastest solar wind leaves the celestial body. Such solar winds are radiation and charged particles sent into space by the sun. So coronal holes could be signs of an impending geomagnetic solar storm.
Because as cheerful as the picture looks, p. It is also true that the sun is currently in a state of increased activity. The Solar Dynamics Observatory recording was successful. Launched on February 11, 2010, NASA’s mission is to find out how solar activity develops and what effects it has.
And thanks to these state-of-the-art satellites, the sun’s rays can also be observed and announced a few days in advance.
