While reading up articles about our Sun, Earth and moon, I came across a recent discovery where it is reported that there is a planet that orbits two suns. It’s difficult to understand how that works, but after putting it in my mind for a while, there is a way…
Moon rocks, that is, rocks from moon. These are geological matters from the earth’s moon that were propelled from the moon into the earth’s atmosphere, and did not evaporate due to heat and crashed to the ground on earth. To find out more, see this page from NASA about lunar…
