(NASA) – This artist’s concept shows a celestial body about the size of our moon slamming at great speed into a body the size of Mercury. NASA’s Spitzer Space Telescope found evidence that a high-speed collision of this sort occurred a few thousand years ago around a young star, called HD 172555, still in the early stages of planet formation. The star is about 100 light-years from Earth.
