Spacecraft Discovers Mercury Truly Is a “Hollowed” Planet
…although not in the way some people mean by the term. 🙂
The latest featured image from NASA’s MESSENGER spacecraft shows the central peak of the 78-mile (138-km) – wide crater “Eminescu” surrounded by brightly-colored surface features called “hollows”. Actually tinted a light blue color, hollows may be signs of an erosion process unique to Mercury because of its composition and close proximity to the Sun.
