Hubble captures Saturn’s aurorae

Two times every 30 years it is possible to view Saturn’s aurorae from where the Hubble telescope is positioned. Since the telescope will be out of commission 30 years from now, this is the only image it will ever take where each aurora can be viewed simultaneously.

The principle behind these aurorae is the same that’s behind the aurora borealis, or northern lights.

No two galaxies are alike

NASA has recently taken an image of a galaxy which is suppose to resemble a snowflake. I guess I can see it, but it’s hard not to just think “Oo, a spiral galaxy” instead.
