Description
Clues to dark matter may be buried in the relics of the oldest stars in the galaxies. The old stars probably formed when the dark matter did, so their motions are probably similar. The astroquarks discuss what this means for understanding that mysterious stuff, plus using X-rays to navigate spacecraft and yet another peculiar meteorite. Dr. Jonathan Kollmer joins the gang for these topics, as well as a sci-fi trivia and nerd news updates.

Elongation
Get your mind out of the gutter and into the celestial sphere. Elongation is also good for a really good time if you're observing the planets. This astronomical angle comes in particulary handy when looking at Mercury and Venus, which spend so much time hanging out near the Sun. So get your sextants ready, you may surprised that you longest elongation does not line up with your superior conjunction. But either way, elongation is here to make sure the Earth moves for you.
