The Sun is the star of the Solar System and makes life on Earth possible. But it's also a danger to our technological civilization. Learn all about our fascinating star in the beautifully illustrated “Our Explosive Sun.”

Charged particles from the Sun caused a Valentine's Day magnetic storm and some beautiful aurorae for those lucky enough to be in high latitudes. Pål Brekke discusses this in his book.

The storm was recorded by the Polar Light Center, Lofoten, Norway

I've just come across a northern lights with moonlight by Fredrik Broms. It made me smile, because Pål Brekke's book gives the usual advice about avoiding bright moonlight for aurora-watching.

But Hurtigruten - Seeing the Northern Lights tells about my experience of aurora-watching by moonlight.

This video of the Sun is really beautiful. If you don't watch the whole thing (4 mins) be sure to watch the first minute and a half because it shows the activity developing & they show the size of it compared to Earth. It's a lot bigger than we are!

The Sun 2012-07-09 by the Solar Dynamics Observatory.

This video is made of images taken by the orbiting SDO on July 9 last year. One second in the video is about 6 minutes. It includes all the exciting stuff the Sun does: solar flare, a coronal mass ejection (CME), and structures that loop into the Sun's corona as the magnetic field lines change.
