Rethinking an Alien World
An artist's concept of Earth and 55 Cancri e positioned side by side for comparison. Credit: NASA
A distant super-Earth named “55 Cancri e” is wetter and weirder than astronomers thought possible. The discovery has researchers re-thinking the nature of alien worlds. 55 Cancri e lies 40 light years away and circles its host star at a distance that is 26 times closer than Mercury is to the Sun. If Earth were in the same position, the soil beneath our feet would heat up to about 3200 F.Researchers have long thought that 55 Cancri e must be a wasteland of parched rock. Now they’re thinking again. Observations from the Spitzer space telescope indicate...
