Sir Patrick Moore and Dr Chris Lintott look at the Galaxy Zoo project, a website which sorts the galaxies of the Universe into spirals and ellipticals.
Hanny van Arkel talks to Sir Patrick about how she discovered a new type of astronomical object, from now on called a Voorwerp (dutch for Object), when she innocently asked what that blue blob was beneath a spiral galaxy. After further studying, the best theory seems to be it's the light from an expired black hole bouncing off a big gasseous galaxy, but time has been reserved on the Hubble telescope after repairs are done to have a closer look.
