Methane rain - it sounds like a great name for a rock song. Scientists at the Lowell Observatory in Arizona have observed a massive methane rainstorm brewing on Titan.
"It's really surprising how closely Titan's surface resembles Earth's," noted Rosaly Lopes, a planetary scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif., at a recent meeting of the International Astronomical Union in Brazil. "Titan looks more like the Earth than any other body in the solar system, despite the huge differences in temperature and other environmental conditions."
Here is an more explanatory article about methane rain on Titan from the Lowell Observatory's blog. They explain that methane rain is not rare on Titan, but that it was rare to capture the data from this large storm system.
