The researchers at the University of Arizona captured some stunning photos of the largest canyon in our solar system. It’s the Valles Marineris canyon on Mars, which is around five times longer and four times deeper than the Grand Canyon in Arizona. Valles Marineris, or Mariner Valley, runs along the Martian equator. It’s 4000 km (2500 miles) long and up to 7 km (4 miles) deep.

Nikon’s history with mirrorless hasn’t been all that great. The Nikon 1 was a good idea, but badly executed. They weren’t very popular in either the low or high end markets, which is why they’re killing them off. Overall they have been largely disappointing when compared to the competition.
