Let’s look at a world 635 lightyears away that just might have a fiery moon of volcanic goodness. To be honest, every aspect of this system is hot. The star is similar our Sun, but the planet is on an 2.8 day orbit around that star, and this orbit makes Mercury look super distant from the Sun. From our perspective here on Earth, this world, WASP-49 A, passes in front of its star, allowing us to see it’s size and the chemical make up of its atmosphere. Observations show the planet to be an extremely overheated and a sibling to Saturn. https://youtu.be/52uJItWKWH4?feature=shared Credit: NASA...
