A new picture shows about 100,000 stars in a globular cluster called Messier 55.
08 May 2012, 03:42 PM ET
The uninhabitable Planet 55 Cancri E is about double the size of Earth and was discovered in 2004. Capturing infrared light (Spitzer's specialty) from a small planet beyond our solar system is a big stepping stone in the search for life.
