Behold: The Beauty of Solar Magnetism
NEW VIDEO! As massive magnetic fusion reactors go, the sun is pretty awesome. This week’s video features all the violence and beauty that erupt from that big bright thing at the center of our solar system.
We’ve got sunspots, coronal loops, solar flares, coronal mass ejections! Even an aurora or two!
And thanks to the fine people of NASA and their fancy satellites, this one is dripping with #spaceporn. Watch below:

On Monday, July 21, the ringed world will appear at a standstill in the sky, relative to the background stars in the zodiacal constellation Libra, the Scales. Astronomers call this…

On Wednesday, August 6, the European spacecraft Rosetta is going to have a close encounter of the best kind with a comet (a chunk of cosmic ice mixed with dirt.) It's called Comet 67P (the P stands for periodic comet, meaning it comes around again and again every six and a half years.) Its more informal name is Comet Churyumov–Gerasimenko, after the two astronomers who discovered it on a 1969 photograph. In mid-July when our photo was taken, the spacecraft was still
