November 7th show...

... is online here. Since I didn't get a chance to do any news on Halloween, and there actually has been a lot to talk about, this was (yet another) all-news show. The outline of this show was:

  • News: Congrats to Prof. Charbonneau (Harvard University), Dr. Bakos (Harvard-Smithsonian Center for Astrophysics), and Dr. Kaltenegger (Smithsonian Astronomical Observatory); NASA creates new Lunar Science Institute, offers $2 million prize for a lunar lander competition; NASA tests a long duration balloon mounted Solar telescope; China launches Moon satellite; new era of space exploration based on international cooperation?; Comet Holmes P still very bright but getting fainter and expanding,
  • Wednesday Morning Astronomer (A discussion of any Astronomy issues raised in Gregg Easterbrook's weekly column on ESPN Page 2, which last week was found here): Earth studies very controversial now, not surprising that funding agencies shying away from it, and star formation, even of massive stars, is quite common in the Milky Way.
  • Solar System: Mechanism to transport material from hot regions near the sun to the cold outer edges of the solar system when it was forming has been identified; ice used to extend all the way to the equator on Mars; bizarre feature on Martian Surface called MFF is likely a combination of ice and dust; asteroid Vesta might be source for weird composition meteorites which have landed on the Earth; new evidence that rings on Saturn created in catastrophic break-up of a moon.
  • Astronomy Calendar in the New York City area
  • Galactic: WASP project found three new planets around other stars, all very close (closer than Mercury to Sun) to parent star with masses similar to Jupiter; fifth planet identified around 51 Cancerae; magnetic filed powered collimated outflow observed from a forming star.
  • Extragalactic / Cosmology: New most massive black hole created in the collapse of a single star identified; peculiar supernova observed - believed to be result of merger of two white dwarfs; exploding white dwarfs at earlier times produced more energy that exploding white dwarfs today; very short burst of radio emission observed from some unknown object outside the Milky Way.
Thanks a lot for listening, hope you enjoy it, and as always, please leave comments and questions below. And don't forget about the upcoming special Thanksgiving Q & A show!
