Researchers have discovered what may be a long-hidden record of ancient impact craters on Venus, shedding light on a planetary history distinct from Earth's.
A team of scientists have found that a single meteorite was likely responsible for creating billions of craters on the Martian surface.
The Deniliquin structure spans up to 520 kilometres in diameter. This exceeds the size of the near-300km- wide Vredefort impact structure in South Africa, which to date has been considered the world's largest.
Thanks to China’s Chang’e-1 and Chang’e-2 lunar orbiters, the number of known craters on the moon’s surface is now more than a dozen times larger than the 9,137 craters that are officially recognized.
