You've heard of earthquakes, and even marsquakes. Our sun also likes to get in on the shimmying action with sunquakes.
research is revealing more about these events and their mysterious origins.
"These earthquake-like events release acoustic energy in the form of waves that ripple along the sun's surface, like waves on a lake, in the minutes following a solar flare – an outburst of light, energy and material seen in the sun's outer atmosphere," NASA said in a statement on Monday.
Researchers originally thought sunquakes were fed by forces in the sun's outer atmosphere, but NASA's Solar Dynamics Observatory (SDO), a sun-watching spacecraft, turned up some eye-catching data when it watched the activity of a sunquake "with unusually sharp ripples emanating from a moderately strong solar flare" in 2011.
SDO's Helioseismic and Magnetic Imager instrument was able to track the sunquake's waves to a source 700 miles (1,130 kilometers) below the sun's surface. That discovery has turned ideas of sunquake origins upside-down.
