This artist’s concept shows what the exoplanet 55 Cancri e could look like. Also called Janssen, 55 Cancri e is a so-called super-Earth, a rocky planet significantly larger than Earth but smaller than Neptune, which orbits its star at a distance of only 1.4 million miles , completing one full orbit in less than 18 hours. The system, which also includes four large gas-giant planets, is located about 41 light-years from Earth, in the constellation Cancer.
Unexpectedly, these observations show that it might be possible for a hot and highly irradiated rocky planet to sustain a, and this bodes well for JWST’s ability to characterize cooler – potentially habitable – rocky planets orbiting Sun-like stars.

The 2016 result already hinted at the possible presence of an atmosphere around 55 Cancri e. For the current study, Demory conducted an independent analysis of the JWST dataset. He explains: “In the past two years, the space telescope CHEOPS which has been developed and built at the University of Bern, has been key in solving several questions that astrophysicists had about 55 Cancri e.
