A giant hole has ripped into the sun

It's called a coronal hole, and it's currently rotating away from Earth – but a few days ago, from its position straddling the equator, it was pointed right at us, directing a stream of particles in Earth's direction.

You probably know about sunspots, solar flares, and coronal mass ejections. A sunspot is a temporary spot on the Sun where magnetic fields get quite a bit stronger. This results in a cooler, darker freckle on the Sun's face.

Solar flares and coronal mass ejections are eruptions, often associated with sunspots, that are caused by a giant release of energy that occurs due to magnetic field lines snapping and reconnecting.

A coronal hole, by contrast, is a large region where the solar magnetic field opens up. They can't be seen in optical light, like sunspots; but when we look in ultraviolet wavelengths, we see huge, dark patches that are dimmer than their surroundings because they are cooler.

The current hole, which at time of writing has almost rotated away to the far side of the Sun, is a big'n; as per Spaceweather, it measures around 800,000 kilometers (500,000 miles) along its longest axis. Jupiter's diameter is around 140,000 kilometers; Earth's is 12,742.

That's no sun!


(hint - it's a giant Eye of Sauron)

It's going to suck us in next time it faces in this direction.
