#LHS3844b #sciencenews पहली बार ज्वालामुखी से भरा ग्रह खोजा गया। super-Earth LHS 3844b ittered with volcanoes LHS 3844b is an exoplanet that was discovered in 2018 by the National Aeronautics and Space Administration’s (NASA) Transiting Exoplanet Survey Satellite (TESS). Now, a latest research conducted by the researchers at the University of Bern has shown that the nightside of the planet is tectonically active, reported SciNews. Scientists discuss, in a peer-reviewed study published in journal Astrophysical Journal Letters, how thermal fluctuations of the super-Earth reveals the exoplanet's solid surface and lack of a substantial atmosphere. LHS 3844b appears to be 'tidally locked', i.e., one side of the planet permanently facing the star, much like we see only one face of the moon, for the same reason. The star-facing side, or dayside, of the super-Earth is about 770 degrees Celsius, while the nightside is much colder, with temperatures below minus 250 degrees Celsius. The research team at Bern suspected that this stark temperature contrast will likely affect how material flows in the planet’s interior. They ran simulations with different strengths of material and internal heating sources, including from the planet’s core and decay of radioactive elements.
