Nasa spot 75000-mile-wide HOLE on the sun

Nasa spot 75000-mile-wide HOLE on the sun

Though the sunspots generally appear to be quite small, the newly released video from NASA shows the patch of intensive electromagnetic activity is actually larger than Earth, which is quite mysterious.

It has been called AR2665 and is capable of producing solar flares that could cause radio blackouts no our home planet.

Sunspots are darker, cooler areas on the surface of the sun, caused by interactions with the star's magnetic field. Because of the drop in solar activity, the sun was speckle-free for two days before this swirling sunspot appeared.

The Solar Dynamics Observatory, one of NASA's space probes dedicated to examine the Sun, has just video recorded a sunspot rotating towards Earth. It could also affect power grids leading to electricity shortages in some areas.

'A new sunspot group has rotated into view and seems to be growing rather quickly, ' announced Nasa.

The sun is now heading into a solar minimum, and its surface had been spot-free for two days before this new sunspot came into view.

NASA's Solar Dynamics Observatory first detected the huge spot last week, and it appears to have lingered through to this week. The word "sunspot" may suggest that the feature is diminutive, and the sun's massive size does dwarf the seemingly floating feature by comparison.
