Why is There a Large 'Hole' in the Sun's Surface?
2 8 621


NASA's Solar Dynamics Observatory (SDO) picked up a large, gaping black ravine in the Sun's surface not that long ago, and it looks like a dark hole is developing on the Sun's surface.

This is a normal part of the nature of the Sun. There are strong magnetic fields produced on the Sun's surface that often trap high-heat plasma on the surface and keep it glowing bright, but sometimes those magnetic fields give way, and the bright plasmas are released into space as solar winds.

The leftover space in the Sun is a chunk that glows less brightly, but over time, it will fill back up with glowing bright plasmas when the magnetic fields change again.

As the solar winds approach the Earth, we'll get more auroras and pretty sights on the poles on the planet.
