(WLTX) - Two fast-growing sunspots that formed in the last two days are six times the size of the Earth, NASA says.

The space agency released an image of the sunspots Thursday. They created the picture using a synthesis of images taken by two NASA observation devices.

Scientists say the phenomenon formed quickly on Tuesday and Wednesday.

Sunspots are formed as the magnetic field on the sun rearrange and realign. They can lead to eruption on the sun's surface, which are commonly known as solar flares.
