SDSS 2201+11
(Preview)
The bits are still warm, having just been downlinked from Hubble overnight. There is still a good bit of processing to be done, cleaning up cosmic rays and so forth. But that said, here is our first look at SDSS 2201+11, first of the Galaxy Zoo AGN cloud galaxies (AKA voorwerpjes) to come up on the telesc...
