NASA's Spitzer space telescope has detected a light source coming from a large earth-like planet.Commentary:
This artist's concept shows the super-Earth planet 55 Cancri e. It's a toasty world 41 light-years from Earth that rushes around its star every 18 hours.
This alien planet at twice the size, 8 times the density with an 18 hour year (uninhabitable by us) was spotted via infrared light. We are quickly, very quickly zeroing in on the ability to find planets close to the size of our own and actually view them!
