NASA Takes a Picture of the Sun in High Resolution and It Looks Like a Happy Face: It’s Caused by the Coronation Hole

NASA shared a comical image of the Sun in which it is seen smiling. The photo was taken by the Solar Dynamics Observatory (SDO) and shared on Twitter by the space agency.

Wednesday afternoon, NASA shared a new image of the Sun and the giant “coronal hole” that can be seen in it, noting that its shape resembles a happy face, However, it is caused by the solar wind being ejected from the star into space.

“NASA’s Solar Dynamics Observatory (SDO) captured the Sun ‘smiling’. Seen in ultraviolet light, These dark spots on the Sun are known as “coronal holes” and are areas where the strong solar wind blows into space.“, reported the space agency through a tweet.

Specific, Coronal holes in the Sun were discovered when an X-ray telescope pointed at our star for the first time flew through the atmosphere., That’s when he saw these dark areas in giant fireballs that orbit the Earth.

According to the Space Weather Live portal, “dark and empty-looking regions are places where the Sun’s magnetic field reaches into space to allow these hot gases to escape.”

The Sun’s “Coronal Holes” Aren’t Actually Holes

These regions, which constantly appear and disappear on the solar surface, They are characterized by a much lower temperature and density than their surroundings and therefore appear dark., But they’re not literally holes, experts say.

it happens because of Continuous change in the magnetic field lines of the Sunwhich differs from the sometimes more visible yellow and orange areas.

“Instead of holding hot gas together, these open magnetic field lines form a coronal hole through which the solar wind can escape at high speed,” explains the Space Weather Portal.

this solar event It Can Also Cause Disturbances—Not Dangerous—On Earth, “When a coronal hole is located near the center of the Earth-facing solar disk, these hot gases flow toward the planet at a greater speed than the normal solar wind and cause geomagnetic disturbances and increased auroral activity. formed,” he notes.
