This week, thousands of astronomers will meet in Washington, DC to present the latest findings from telescopes around the planet. It’s the 215th meeting of the American Astronomical Society. So, what’s been showing up in the skies lately? JPL and NASA have just announced the discovery of 5 exo-planets similar in size to Uranus and Jupiter. Are there habitable planets close to us? What are they composed of, and how many more might Kepler find?
