NASA’s infrared Spitzer Space Telescope spotted light from the alien planet 55 Cancri e, which orbits a star 41 light-years from Earth. A year on the extrasolar planet lasts just 18 hours. The planet 55 Cancri e was first discovered in 2004 and is not a habitable world. Instead, it is known as a super-Earth because of its size: The world is about twice the width of Earth and is super-dense, with about eight times the mass of Earth. But until now, scientists have never managed to detect the infrared light from the super-Earth world. Spitzer first detected infrared light from an alien planet in 2005.
A team of astronomers from the Massachusetts Institute of Technology (MIT), the University of British Columbia (UBC), the Harvard-Smithsonian Centre for Astrophysics and the University of California at Santa Cruz (UCSC) using Canadian space telescope MOST (Microvariability & Oscillations of Stars) has found a new exoplanet.
