Default Hanny's Voorwerp

One of the strangest objects ever found in space. Discovered by Dutch schoolteacher Hanny van Arkel as she was taking part in a public outreach project by ESA to let non-professionals classify galaxies, called the Galaxy Zoo Project. She posted to their forum asking astronomers for an explanation of the strange object. No one at the time could form a reasonable explanation so astronomers ordered observing time on the Hubble and the team have released the sharpest image yet of the object, named Hanny's Voorwerp (Dutch for 'Hanny's Object').

Interesting... no idea what it is though? Perhaps related to the formation of a star if it is a cloud of gas.

What's so interesting about it is its specific colour and size. Giant clouds of gas and dust usually form galaxies like IC 2497 seen right above it. This cloud is the size of the Milky Way, has a very irregular shape and has a strong green colour.

No worries though as it is thought to be 'light echoes' from a quasar that has since died but the light it shone on the cloud is still reaching us. Oxygen molecules ionized by the quasar gives it a narrow wavelength band of green.
