Webb discovers carbon dioxide and hydrogen peroxide on Pluto's largest moon

Nasa's James Webb Space Telescope has discovered traces of carbon dioxide and hydrogen peroxide on Cheron's surface, sparking new interest in Pluto's largest moon

Carbon dioxide, hydrogen peroxide detected on Pluto's largest moon 'Charon'

Scientists have detected the gases carbon dioxide and hydrogen peroxide on Pluto's largest moon, 'Charon', which they said could help understand how icy bodies originated and evolved in the outer Solar System. Once considered the ninth and last planet of the Solar System, Pluto was demoted to a 'dwarf planet' status in 2006, when members of the International Astronomical Union voted to scientifically define a 'planet' for the first time. According to the resolution passed then, a dwarf planet is one that has not been able to create a clear orbit for itself, free from debris. Pluto's orbit, lying in the Kuiper belt region beyond the planet Neptune, was thought to cross with those of other objects. Charon is the largest of the five known moons of Pluto and has been studied since it was discovered in 1978. Being extremely cold, there's practically no chance for life to exist on Pluto and water, essential for life, is present as ice. The team, led by researchers at the Southwest Resear
