Absence of a thick atmosphere on the terrestrial exoplanet LHS 3844b

Jupiter is a gigantic ball of churning gas clouds, and that makes it hard to see what's in the middle. It's believed to be a relatively small, rocky core, but data from the Juno probe found that it's less dense and more spread out than expected. Now, astronomers believe they have an answer – a huge ancient planet, with 10 times the mass of Earth, crashed into the gas giant in the early days of the solar system...
