Be lucky!

Wish I could remember the name of the nebula. Ert something? Will need to check or it will annoy me. Randomly wandered to St. Andrew's Square where there's an outdoor exhibit advertising the upcoming Science Festival (March 30 - April 18th? Something like that)

This year's theme is Unseen Worlds. I doubt the pigeon/seagull/other urbanised avian saw where it's effluent landed...
