Jupiter’s moon Europa is covered in weird double ridges. Now one’s been spotted in Greenland
Jupiter's moon Europa is covered in weird double ridges. Now one's been spotted in Greenland,Europa is one of the most intriguing worlds in the solar system. It’s the smallest of Jupiter’s big moons, and just a wee bit smaller than our own Moon. When the two Voyager spacecraft flew by in 1979 they sent back relatively high-resolution images of it, revealing several surprises. One is that the surface is globally very smooth, with very few craters. That implies the surface is young; any old craters must have been smoothed over, repaved in relatively recent geologic history.
