Reader Coel called my attention to a picture (I won’t give the URL, as it also has the answer) showing the Philae lander resting on the comet Comet 67P/Churyumov–Gerasimenko. The picture was taken by the parent Rosetta spacecraft just three days ago as it came within 3 km of the comet surface.
Can you spot the lander? I would rate this one HARD! I’ll post the answer at noon. Click twice (with a break between the clicks) to make the photo big.
If you spotted it, you can tout your success in the comments, but PLEASE DO NOT GIVE AWAY THE LOCATION IN THE COMMENTS.
