Humongous waves of hot plasma roiling on the surface of the sun appear to be moving at speeds as high as 4.5 million miles per hour, a new study found. The waves are so huge it would take up to 16 Earths, end-to-end, to match them.
It's the first unambiguous evidence that the sun's lower atmosphere contains such superfast "magnetosonic waves," scientists said.
The fast waves have velocities of 2.3 million to 4.5 million mph (1,000 to 2,000 kilometers per second), periods in the range of 30 to 200 seconds, and wavelengths of 62,000 to 124,000 miles (100,000 to 200,000 kilometers), equivalent to stacking between eight to 16 Earths on top of one another.
