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.
A new thermal map of a super-Earth exoplanet is puzzling astronomers.
New observations from the Hubble Space Telescope are helping characterize the atmospheres of exotic planets such as 55 Cancri e.
Following a wildly popular contest, the International Astronomical Union has named 14 stars and 31 planets that orbit them.
By combining nearly 1,500 observations with sophisticated computer models, astronomers have shed light on a nearby planetary system, proving that the planets' bizarre orbits will actually remain stable for the next 100 million years.
Two research teams combine forces to study the wildest exoplanet yet identified.
Observations of nearby super-Earth 55 Cancri e reveal huge, as-yet unexplained changes in the exoplanet’s infrared emission, and volcanoes are one possible cause.
