Exoplanet Pleasure

 When I began my studies at the University of Arizona, I was under the impression that astronomy was the study of everything that the night sky had to offer. Though that is mostly true, it did not take me long to discover that planetary science was its own discipline and quickly became my favorite area of study. So, needless to say, all things exoplanets are especially interesting to me.

Today NASA announced the discovery of over 1,200 new potential exoplanet candidates. (Note: These are candidates and have yet to be confirmed.) This discovery is so incredible because of the number of potential exoplanets discovered by one telescope in such a short period of time in such a small field of view. The approximately 500 exoplanets discovered prior to Kepler took a span of nearly 20 years to find. Kepler found its astounding number of exoplanet candidates in less than two years.

Kepler was launched in March 2009 and is the 10th mission of NASA’s Discovery Missions. Kepler saw “first light” a month later when its dust cover was blown off with its optics pointed towards the constellations of Cygnus and Lyra. Its three-and-a-half-year mission objective is “to explore the structure and diversity of planetary systems.” I certainly hope this is one mission that will be extended.

An especially exciting element of the Kepler mission is that the data, released ahead of schedule, is available to citizen astronomers at PlanetHunters.org where anyone with a little time and patience can assist Kepler astronomers in confirming the potential candidates as true exoplanets. (You do not need to be an astronomer, or own a telescope, to participate.) Imagine how exhilarating it will feel when your “favorite” exoplanet is officially added to the Planetary Society’s Catalogue of Exoplanets.

In addition to watching the NASA news conference today, I read a number of articles in the media from links on Twitter (thank you to all my astro-tweeps), along with a little extra research of my own. Below you’ll find a list of those for your exoplanet pleasure.

  1. When I first began college, I wanted to major in astronomy. My parents were afraid it would be tricky to get a job in the field, and I changed majors to psych. As you know, I eventually made my way to science education. I still wish sometimes I could be an astronomer, but I love that I can help kids fall in love with space 🙂

    Thanks for sharing all about Kepler and the exoplanets.

  3. Awesome stuff, glad I found this. I’m a huge Rigel Kent fan and I hope you can write more specifically about that. Pesonally, I’m visiting the highlands of central Mexico (about 7000 ft elev) just so I can watch Alpha Centauri. I’m usually up in the middle of the night watching it. Crazy, I know. Anyway, can you pls write about A-B Cent? Thanks!
