"If any life was present on either planet, the massive collision would have wiped out everything in a matter of minutes — the ultimate extinction event," said co-author Gregory Henry, an astronomer at Tennessee State University (TSU). "A massive disk of infrared-emitting dust circling the star provides silent testimony to this sad fate." Also of interest is the fact that BD+20 307 is composed of two stars, both very similar in mass, temperature and size to our own sun and that they orbit each other every 3.42 days. -------------------- Mike (tVA) I am here to tell you the Truth. We have been created as slaves to be used as batteries for an alien race. You must give up everything you hold dear in this illusionary world so that you may save yourself in the real world.

If the collision that created the Moon is a realistic model for all this, then embedded within that dust cloud may be the seeds of a growing new planet. Much of the dust may be dissipated, but some of it may re-form into another body. -------------------- "S.O.E."
