Getting to know super-Earths: Using Hubble to study mysterious exoplanet

15 octubre 2014

Results from NASA’s Kepler mission have indicated that the most common planets in the galaxy are super-Earths — those that are bigger than Earth but smaller than Neptune. We have no examples of these planets in our own solar system, so astronomers are using space telescopes to try to find out more about these worlds. Most recently they used Hubble to study the planet HD 97658b, in the constellation Leo.
