(This Hubble Space Telescope composite image shows a ghostly ring of dark matter in the galaxy cluster CL0024 + 17. Click on image to enlarge.)
Every Thursday, I post a very large photograph of some corner of space captured by the Hubble Space Telescope and available online from the picture album at HubbleSite.

TIME-LAPSE MONDAY
Here's your weekly time-lapse video showing a fascinating natural event. Hat-tip to WordWeaverLynn for the original link, and Wired Science for the article which brought them all to our attention.
My longest time lapse so far. 1661 images were photographed over a time period of 5 days, 18 hours and 25 minutes. A Canon PowerShot G3 digital camera connected to a computer was programmed to take one shot every 5 minutes. Processing was done with Photoshop and VirtualDub. The substrate was rye, the casing consisted of peat moss, vermiculite and crushed limestone.
