One such fascinating fact about Pluto is that its snow is red in color. The notion of red snow may seem peculiar and raise questions about the possibility of life on this icy planet. However, the reality behind Pluto's crimson snow lies in its unique atmospheric conditions and the presence of various chemical compounds.
Image by author using Bing Imagine a lovely winters day with blue skies and white snow. Now image that but with bright red snow. It sounds odd doesn't it.
But this is the reality on Pluto. Here. Explore the true color version of Pluto's giant moon, Charon.

On Pluto, the mountain peaks are covered with frozen methane. Because of its specific chemical composition, the snow on Pluto is red. Astronomers discovered it in 1930, and Pluto was considered.
Comparing the spectral data with images of Pluto shows the water ice locations match areas that appear primarily red in color. The Snow on Pluto Discover Hubble telescope images of Pluto revealing intriguing surface details and patterns in frozen methane and nitrogen.! It's only where fresh, white methane snow covers the tholin-rich regions that a white color reappears. Image credit NASA/JHUAPL/SwRI, of methane snow atop tholin.
Pluto, a dwarf planet, exhibits a captivating array of colors, ranging from pale white to dark red, due to the complex interactions between its surface composition and the feeble sunlight it receives. Nitrogen ice dominates the surface of Pluto, which is a key factor in defining its albedo or overall brightness, while methane frost contributes to the planet's distinct reddish hues. Pluto's surface has three primary color hues: red, white, and blue.
This is due to the complex chemistry of its icy terrain and atmospheric processes. The red areas, such as Tombaugh Regio, are caused by tholins-complex molecules formed when ultraviolet (UV) light from the Sun interacts with methane (CH₄) in Pluto's thin atmosphere. These molecules then settle onto the surface.
Mountains on Pluto look strikingly similar to white-capped peaks on Earth, but these cold, alien mountains got whitened in a completely different way.
