The largest valley in the solar system revealed in stunning new photos

About 87 million miles (140 million km) above Grand CanyonA larger and larger abyss, penetrating the bowels of the Red Planet. Known as Valles Marineris, this system of deep and wide canyons is more than 2,500 miles (4,000 km) along the Martian equator, and stretches nearly a quarter of the planet’s circumference. This wound is in the bedrock Mars It is nearly 10 times the length of the Grand Canyon on Earth and three times deeper, making it the largest single canyon in Solar System And according to ongoing research from the University of Arizona (UA) in Tucson, one of the most obscure ones.

Using an incredibly high-resolution camera called HiRISE (short for High Resolution Imaging Scientific Experiment) aboard the Mars Reconnaissance Orbiter, UA scientists have taken close-up shots of the planet’s strangest features since 2006. Despite some really stunning photos of Valles Marineris – like the one below , Published on HiRISE December 26, 2020 – Scientists are still unsure how the Giant Canyon Complex formed.
