<font color="yellow">a release of radiation and energy by a black hole into a neighboring planet.</font><br /><br />Actually, the radiation is released into a neighboring galaxy (which, undoubtably would have many planets). The type of radiation is mostly gamma and x-rays, but it probably includes every type of high energy rays and particales imaginable. Here is an sdc article on the subject: <br /><br /><br />http://www.space.com/scienceastronomy/071217-death-star-galaxy.html <br /><br />BTW, there is already a thread on this topic, you should probably post your questions in that thread, which is here:<br />http://uplink.space.com/showflat.php?Cat=&Board=sciastro&Number=848402&page=0&view=collapsed&sb=5&o=0&fpart=1#Post848536
