APOD 3.8

This is an artist's rendition of what one of two extrasolar planets may look like. Evidence found by the Spitzer Space Telescope indicates that planets in HD 209458b and HD 189733b. Specifiacally, Spitzer compared infrared shots of the planets as they eclipsed their stars with their normal infrared shots. No water vapor was detected in these planets, and the two planets were classified as "hot jupiter's;"that is, their roughly the size of Jupiter, but have orbits similar to Mercury's. These results, however, are preliminary. But the fact that these planets have atmospheres may just bring us a step closer to finding life elsewhere in our universe.
