Methane on Pluto’speaks

New Horizons team has discovered a chain of exotic snowcapped mountains stretching across the dark expanse on Pluto, informally named “Cthulhu Regio”, that has methane — an important trace gas in Earth’s atmosphere. The new images reveal a mountain range located in southeast Cthulhu that is 420 km long. The range is situated among craters, with narrow valleys separating its peaks. The upper slopes of the highest peaks are coated with a bright material that contrasts sharply with the dark red color of the surrounding plains. Scientists think this bright material could be predominantly methane.
