The space telescope Spitzer of NASA has detected for the first time the light of a "super-earth", called "Cancri 55 e" with infrared light. It's localized in the solar system of the star "Cancri 55", relatively "near" us, at 41 light years.
That is a historic moment because it opens another way to search life in other planets in space. The spaceship is very speciallized in the study of far atmospheres, and this technique can be used now in habitable planets.
The "super-earths" are bigger than our planet but are lighter than others, like Neptune. Cancri 55 e has the double of size than The Earth. It's covered of water (liquid and gas) and revolves around a sun.
Middle Cancri 55 e is always dark and the other part is always illuminated. This part is over 2000 grades Kelvin, then there metal can be melted!
