A giant sunspot that’s at least six times the diameter of Earth has formed on the sun in less than 48 hours, according to NASA.
Sunspots form when the sun’s magnetic fields rearrange and realign. They tend to be unstable andcan lead to solar flares.
According to a news release, scientists from NASA’s Solar Dynamics Observatory watched the sunspot rapidly grow on February 19 and 20.

A colossal sunspot on the surface of the sun is large enough to swallow six Earths whole, and could trigger solar flares this week, NASA scientists say.
The giant sunspot was captured on camera by NASA’s Solar Dynamics Observatory as it swelled to enormous proportions over the 48 hours spanning Tuesday and Wednesday (Feb. 19 and 20). SDO is one of several spacecraft that constantly monitor the sun’s space weather environment.
