Gary’s Pumpkin Pie and black holes with plasma jets

18 November 2012

At www.newscientist.com/article/dn22509-pumpkin-pie-craters-on-mercury-are-… … the link was forwarded by member Gary and the story is derived from data sent back by NASAs Messenger spacecraft. The weird shapes and cracks are caused by lava cooling and contracting – or that is the explanation. What do you think?

Over at http://phys.org/print272270762.html … computer models, black holes, and plasma jets – it is all here. There is an image of a spinning black hole that is in the act of flaring, producing a powerful jet along the axis of spin. A paper in Science is actually saying black holes have magnetic fields and plasma jets – so is it a black hole? Well, Thunderbolts will no doubt have this issue online some time later this week. Some nice images and a video clip. Enjoy.
