NASA's Lunar Reconnaissance Orbiter images reveal ancient cracks called grabens on the Moon, indicating the lunar crust was pulled apart billions of years ago, with ongoing minor extension suggesting the Moon is still slowly changing due to cooling and tectonic stresses.
New research suggests that Mercury, the smallest planet in our solar system, may still be shrinking today. Scientists from The Open University in the UK analyzed images taken by the NASA MESSENGER spacecraft and discovered geological features called grabens, indicating recent tectonic activity and suggesting that Mercury's core may not have completely cooled. The upcoming BepiColombo mission by the European Space Agency and the Japan Aerospace Exploration Agency will provide further observations and data on Mercury's shrinking process.
