Rocky planets larger than our own, so-called super-Earths, are surprisingly abundant in our Galaxy, and stand as the most likely planets to be habitable. Getting a better idea of their interior structures will help predict whether different planets are able to generate magnetic fields – thought to be conducive for life to survive.

by Jonathan O’Callaghan From the first discoveries of planets beyond our solar system in the 1990s, we now know of thousands of alien worlds, some of which could even be habitable to life as we know it. Now we need to detect more of these exoplanets and study them in detail, says astronomer Dr Michaël … Read more
