Another week, another roundup of your questions. This week listeners asked: are we all going to die in 2012 when the solar system passes through the galactic plane? Did Venus make the Moon? And what will extraterrestrials see when the Sun is dead and gone? And there’s even more. If you’ve got a question for the Astronomy Cast team, please email it in to info@astronomycast.com and we’ll try to tackle it for a future show.

Let’s start the clock again, and see what happens to the smallest stars in the Universe; and what happens to the largest.
Questions Show – Running Out of Gravitons and Hitting the Brakes at Light Speed
