A new ultraviolet mosaic from NASA's Galaxy Evolution Explorer shows a speeding star that is leaving an enormous trail of "seeds" for new solar systems. The star, named Mira (pronounced my-rah) after the latin word for "wonderful," is shedding material that will be recycled into new stars, planets and possibly even life as it hurls through our galaxy.
Your job is very simple! All you need to do is look out for the features that mark out spiral and elliptical galaxies. In fact, as you're a human and not a computer, most galaxies should be easy to classify since they're obviously spirals or obviously ellipticals. On this page, you will practice classifying galaxies. On the next page, you will take a short trial to test your skills. If you don’t pass the trial, you can try again. Once you pass the trial, you can start contributing to Galaxy Zoo science!

The scientists behind the Cassini orbiter have announced the discovery of Saturn's 60th moon, a little thing that showed up in time-lapse photography of the ringed planet. Jupiter still leads this moon race with 63 known satellites - but Saturn could soon pull ahead, at least temporarily.
