A picture of “smiling” sun captured by NASA’s Solar Dynamics Observatory has gone viral on social media.
The picture was shared on Twitter by the NASA Sun, Space & Scream on Wednesday with caption “Say cheese! Today, NASA’s Solar Dynamics Observatory caught the Sun “smiling.” Seen in ultraviolet light, these dark patches on the Sun are known as coronal holes and are regions where fast solar wind gushes out into space,” tweeted NASA’ s handle which especially study the Sun.”
Meanwhile, space experts said that the Sun is not actually as cheerful as it appears to be in this image.
Coronal holes, which are the areas from which rapid solar wind gushes out into space, are what are observed as dark spots in ultraviolet light.

Because of the complex stream of solar winds they release, these coronal holes can also trigger a solar storm on Earth.
These coronal holes, which are basically open magnetic field areas in the Sun’s atmosphere that are cooler and denser than the surrounding plasma, coincidentally positioned, giving rise to the face-like pattern.
Humans are not directly harmed by solar storms, and their health is unaffected, but technologies, particularly those related to radio, communications, GPS, etc., are negatively impacted.
