Can planets form around supermassive black holes? 🌌 New simulations suggest the dusty disks around actively feeding supermassive black holes could produce enormous planet-mass objects — with some potentially growing massive enough to become stars.

What if a rocky planet didn't have a core? That can't happen, can it? It should differentiate... well, there might be a set of circumstances under which that might happen. If it does, they're going to be a bit strange. As to how they might be weird. They might deform more due to rotation and gravitational distribution; they might have an unstable or no magnetic field, and the minerals on their surface would definitely be exotic.

Earth-like LHS 1140b May Feature The First Atmosphere Found On Exoplanet

Finding another planet outside of our solar system that can comfortably be called ‘Earth-like’ is one of those discoveries that — if confirmed — would be a major event. The …

University of Oxford study found that planets 1,113 light years away are 1,000 times bigger than Earth, but lighter than cotton candy

Une étude de l’université d’Oxford a trouvée que des planètes à 1113 années-lumières sont 1000 plus grosses que la Terre, mais plus légères que de la barbe à papa

These planets are 1,000 times bigger than Earth, but lighter than cotton candy: study | CBC Radio

About 1,113 light years away from Earth, locked in orbit around a single star, there are two planets that appear to be the size of Jupiter, but have the density of "a nice blob of shaving foam, fresh from the can."

The geology of chocolate bars... It's more than 50 years since we left the Moon and, as far as I can see, we still have no equivalent for the prefix in the word 'Geology', the science of the physical structure of the Earth and its rocks. We have Exo-geology, and lunar geology and planetary geology but no xxxology where xxx is a prefix denoting the study of non-Earths. Who can help me out, here? #Science #Exoplanets #Geologyhttps://www.jpl.nasa.gov/edu/resources/project/describe-rocks-like-a-nasa-scientist/
