This artistic representation shows how an asteroid, destroyed by the enormous force of gravity of a white dwarf, has formed a ring of dust particles…
The Moon is shrinking as its interior cools, getting more than about 150 feet (50 meters) skinnier over the last several hundred million years. Just…
