Hubble Telescope Zeroes In On Green Blob In Space

In 2007 a Dutch school teacher discovered Hanny's Voorwerp, a large "green blob" in space. NASA's Hubble Space Telescope has recently taken pictures, displaying its star generating power. The new photo was released at the AAS meeting in Seattle.

The blob is about the size of the Milky Way Galaxy and is nearly 650 million light years away.

I read another article about this and it said that the blob is hydrogen gas being lit up by a nearby quasar. How is it giving birth to new stars?

"Parts of the green blob are collapsing and the resulting pressure from that is creating the stars."

It would appear that parts of Hanny's Voorwerp are collapsing and creating large amounts of pressure that in turn creates stars.

"Stars form, like the planets, as a nebula rich in material collapses in upon itself due to gravity. The cloud slowly contracts forming a rotating disk. Most of the material is in the center of the cloud. This area, if there is sufficient mass, will become the star. clumps of Matter run into each other in a process called accretion. Larger and larger lumps are formed. The protostar gets ever larger. It also contracts, and the pressure causes the interior to heat up."

- From a yahoo! answers post somewhat clarifies, although it's difficult to prove the validity of some random person on the internet.
