Colorful Mystery
Here's a new, truer-color rendering of the Voorwerp (lower center). Although it looked blue on the Sloan photo, the object actually now appears to be fairly green, observes Keel, who performed spectral analses of the huge mystery cloud.

Nearly a year ago, astronomers at several universities recruited citizen scientists to help them catalog distant galaxies that had recently been photographed as part of the Sloan Digital Sky Survey. A high-school physics teacher in the Netherlands who was participating in this project, known as Galaxy Zoo, appears to have scored a major coup. She brought a weird blue object to the attention of the professional zookeepers, according to a cosmologist associated with the zoo.
That novelty appears to be a quasar whose intense radio emissions have been fueling star births.
Alex Szalay of Johns Hopkins University, and a project director for the National Virtual Observatory, was today’s keynote speaker, here in Pittsburgh, at the Joint Conference on Digital Libraries. He reflected on how much data had been collected during the Sloan survey, which wrapped up a month ago. Its organizers expected this project, designed to be the most comprehensive photographic imaging of the northern skies, to take some five years. It actually took 16.
In the process, it collected more data than astronomers decided they could ever realistically review and catalog. So they released more than a million never-before-seen images for the public to peruse in the comfort of their own homes. After a bit of online training, each was asked to categorize the type or shape of galaxies in any image they viewed.
“We expected to get several hundred people a day” taking part, Szalay says. In fact, the first day alone there were several million...

Here's a close up of the green spot.

Funny thing is that if you magnify the picture to about 900% it really does look like Kermit. Also, another apparently smaller green object appears to the right of the main one.
