Volcanoes might light up the night sky of this planet

E-Mail IMAGE: This artist s illustration represents the possible interior dynamics of the super-Earth exoplanet LHS 3844b. The planet s interior properties and the strong stellar irradiation might lead to a hemispheric tectonic regime.. view more Credit: © Universität Bern / University of Bern, Illustration: Thibaut Roger On Earth, plate tectonics is not only responsible for the rise of mountains and earthquakes. It is also an essential part of the cycle that brings material from the planet s interior to the surface and the atmosphere, and then transports it back beneath the Earth s crust.

Oph 98A is the more massive and therefore more. view more Credit: © University of Bern, Illustration: Thibaut Roger Star-forming processes sometimes create mysterious astronomical objects called brown dwarfs, which are smaller and colder than stars, and can have masses and temperatures down to those of exoplanets in the most extreme cases. Just like stars, brown dwarfs often wander alone through space, but can also be seen in binary systems, where two brown dwarfs orbit one another and travel together in the galaxy.
