Your instruments detect large quantities of helium in the upper atmosphere and high levels of carbon dioxide in the lower atmosphere. How many layers of atmosphere do you need to pass through in order to reach the planet's surface?
Not all stars are gigantic. Neutron stars have a radius of about 10 km (6 mi), but they might have a mass that is a few times the size of our Sun. These dense stars, born from core-collapsing supernova star explosions, also rotate at incredible speeds – an estimated 600-712 rotations per second!
