Astrosphere for June 15, 2007

Welcome back to the astrosphere, here’s what’s happening in space… space… space.

Today’s astrophoto from the Bad Astronomy/Universe Today forum is from Dave Mitsky. It’s NGC 7635, aka the Bubble Nebula.

The Daily Galaxy has a look at Gliese 581c’s big brother. Probably not a great place for life.

I covered the double supernova here. Phil Plait from Bad Astronomy has a great description of it was well.

SciGuy has a story about a successful test of a plasma rocket.

Tom’s Astronomy Blog has a nice comparison between Antares and our Sun.
