You’ve heard of earthquakes, and even marsquakes. Our sun also likes to get the action flickering with the sun’s rays. NASA research is revealing more about these events and their mysterious origins.

“These earthquake-like events emit acoustic energy in the form of waves that ripple along the Sun’s surface, such as lake waves in minutes after a solar lake – an outbreak of light, energy, and material seen in the sun’s outer atmosphere.” NASA said in a statement on Monday.

Researchers originally thought that suncakes were fed by forces in the sun’s outer atmosphere, but NASA’s Solar mobility observatory (SDO), a sun-observing spacecraft that replaced some eye-catching data in 2011 when it saw an earthquake activity with “unusually strong waves emanating from moderately strong solar flashes” .

This Sunquay film shows the area on the left of July 30, 2011 and the earthquake waves on the right, which appears 42 minutes after the associated solar flare.


The SDO’s heliosemic and magnetic imager device was able to track sun waves up to 700 miles (1,130 kilometers) above the surface of the sun. That discovery turned the idea of ​​the origin of the Sun upside down.

In late 2020, a team of researchers published a study on drowning in The Astrophysical Journal Letters. “Scientists still have not identified what exactly causes the mechanism to cause sunlight, although the results indicate that their origin is likely to lurk beneath the surface,” NASA said.

Researchers hope to collect more data about the sunflower to see if there is a similar deep origin story for the 2011 event.

The Sun has been a major hub of NASA and other agencies in recent years. We have seen Unprecedented views of our host star And this Parker Solar Probe And Solar orbiter spacecraft Sending back new data as soon as we want to understand the functioning of the Sun and how it affects our solar system and the Earth.
