  • A Symphony of Science

    Today, an announcement came out about a paper led by Ravi Kopparapu that updates the habitable zone, moving it further out in space from host stars. I really like this paper (on which I’m a co-author) because it demonstrates how science often progresses: through a series of incremental improvements, the totality of which has profound implications for a handful of known planets. Here’s the new habitable zone, in pretty picture form (courtesy Chester Harman/Penn State):

    You see, the habitable zone reported in the paper is based

  • Grease those wheels!

    Bad news for exoplanet lovers: Kepler is in trouble. There are gyroscopic wheels that help point the spacecraft towards its target stars (and planets!), and one of them is experiencing too much friction. They tried a few remedies, but none of them seemed to get rid of it. So now they’ve put the spacecraft in “safe mode” in hopes that a little rest will do it some good.
