Its time once again for another Where In The Universe Challenge. The goal of this challenge is to test your skills and knowledge of the cosmos. Guess where in the Universe this image is from, and give yourself extra points if you can guess which spacecraft is responsible for the image. Post your guess in the comment section (no links to hints please!) and check back tomorrow for the answer. Good luck!
UPDATE (2/14) The answer has now been posted below!
Did you recognize this intriguing globular cluster of stars? Just kidding! — it’s actually the constellation of city lights surrounding London, England, here on planet Earth, as recorded with a digital camera by astronaut Don Pettit from the International Space Station. Taken in February 2003, north is toward the top and slightly left in this nighttime view. The encircling “London Orbital” highway by-pass, the M25 , is easiest to pick out south of the city. Even farther south are the lights of Gatwick airport and just inside the western (left hand) stretch of the Orbital is Heathrow. The darkened Thames river estuary fans out to the city’s east. In particular, two small “dark nebulae” – Hyde Park and Regents Park – stand out slightly west of the densely packed lights at the city’s core.
The crew of the International Space Station acquired this image shortly after 7:22 p.m. local time on the evening of February 4, 2003. Either thin, low clouds or perhaps fog is evident in the fuzzy character of patterns for some of the surrounding smaller cities while that of the warmer urban center is still clear and sharp.

Check back next week for another WITU Challenge (and sorry for the delay in posting the answer this week!)
