Our incredible star – the sun.

Amazing NASA footage.

Taking a bit of an emotional rest after the last two days!

Wanted to share with you something that Dan Gomez sent me.  It was an email with a link to an item in the British newspaper, The Independent. It was an article headlined: Incredible Nasa footage shows a ‘hole in the Sun’ that’s bigger than Jupiter. The article opened:

Nasa has released new footage showing a square ‘hole’ in the Sun captured by the space agency’s Solar Dynamics Observatory (SDO) spacecraft.

The phenomenon – known as a coronal hole – is perfectly normal and shows an area of the Sun’s corona that contains plasma with lower than average density. Nasa says that the coronal hole appears dark in the ultraviolet filter “as there is less material to emit in these wavelengths.”

It was then a simple matter to go to that NASA report and enjoy this stunning image.

Coronal Hole Squared A coronal hole, almost square in its shape, is one of the most noticeable features on the Sun of late (May 5-7, 2014). A coronal hole is an area where high-speed solar wind streams into space. It appears dark in extreme ultraviolet light as there is less material to emit in these wavelengths. Inside the coronal hole you can see bright loops where the hot plasma outlines little pieces of the solar magnetic field sticking above the surface. Because it is positioned so far south on the Sun, there is less chance that the solar wind stream will impact us here on Earth. Credit: Solar Dynamics Observatory/NASA

NASA also released the following video.
