By observing Pluto and Titan, scientists highlighted an absorption line at 5.11 micrometers. No previous publication mentions a similar line, whether for other planets in the Solar System or for exoplanets. The researchers therefore believe that this signature comes from an unknown molecule, present only on these two icy bodies.
It is remarkable that Pluto and Titan have very little in common. Titan, Saturn's largest moon, has rivers and oceans of liquid methane on its surface, and is larger than Mercury. Pluto, on the other hand, is a frozen dwarf planet, twice as small as Titan and four times farther from the Sun. Yet the two worlds share atmospheres rich in nitrogen and methane. But this unknown molecule appears to be located on their surfaces, not in their atmospheres.
On Pluto, the absorption line is about three times stronger than on Titan, indicating a higher concentration. On Titan, the distribution is uneven: the trailing hemisphere (the one opposite the direction of rotation around Saturn) shows stronger absorption than the leading hemisphere. This asymmetry intrigues researchers, who are working to understand its origin."
