In other news. ESA launched the Herschel space telescope. (Along with another spacecraft call Planck)
It has a 3.5m mirror, making it "teh biggest!11", but it will be observing in infrared.
An interesting thing about it, is it's orbit, or specifically, the lack of it, since it is actually heading for L2.
L2 is a Lagrangian point, and Lagranian points are areas in space where the sun/earth gravity cancels each other out.

There, it will enter something called a lissajous orbit, around it. So basically it will be "orbiting" what appears to be empty space.

This concludes our space lecture for today.
