M51 and M51b are strongly interacting. According to current models, B came from behind M51, passed through the disk some 600 million years ago, was pulled back by gravity, and passed through again about 100 million years ago, to its current location behind M51. This caused strong distortions in both...

Re: 06/12/08 Mars Lander Photo

Hello All, Some thoughts........ 1) Ice was melted by the thruster from a larger, shallower area at first and then, as the heat became more concentrated the closer it got, a deeper, more pin-pointed melting occurred which forced water out of the cone and onto the surrounding area to spread and refr...

Get out a camera, and find a darkish setting. Put a really bright object in that setting, and take a short exposure.
