The findings are based on a new study of meteorite samples and rare atomic nuclei. *Great rift valley found on Mercury A giant rift valley which may be evidence of buckling of planetary crust due to global contraction has been discovered on Mercury. The massive feature – which dwarfs the Grand Canyon -- is over a thousand kilometres long, some 400 kilometers wide, and over 3 kilometers deep. *Gravity Wave Observatory starts new observation run After a series of upgrades, the twin detectors of the LIGO Laser Interferometer Gravitational-wave Observatory are back in operation to continue their hunt for ripples in the fabric of space time known as gravitational waves.
