Previous studies of 55 Cancri e haven’t been able to determine whether this super-Earth hosts an atmosphere. A new study settles the question.
Tantalizing new observations hint that there's a lot more going on in the Proxima Centauri system — the one that hosts the exoplanet nearest Earth — than meets the eye.
