Re: Terry's Astronomy Thread.
What's in the sky tonight?
October 8, 2013
-The Moon shines above Venus in twilight. Depending on where you are in North America, the Moon, Venus, and fainter Antares form a nearly equilateral triangle.
-A minor CME, propelled towarded Earth by a magnetic filament erupting on the sun, could strike our planet's magnetic field during the late hours of Oct. 9th. NOAA forecasters working through the US government shutdown estimate a 30% to 40% chance of polar geomagnetic storms.

Earth is not the only planet in the solar system to be struck by the sun's radiation. Planets as far as Saturn have been known to form auroras. This sequence of three images taken by Hubble Space telescope of Saturn was taken over two day intervals. The auroras are caused by charged particles entering the atmosphere of Saturn, much like how it happens on Earth. Auroras have also been discovered on Jupiter.
