…Billion Comets.

"Pluto may not be a planet, but it remains one of the most intriguing objects in the outer Solar System. Its unexpected chemical composition has confounded scientists for years, but a new theory may finally hold the answer. Pluto, according to a pair of Southwest Research Institute scientists, is basically an overgrown comet.

One of Pluto's most striking features is its bright Tombaugh Regio, a smooth, heart-shaped area consisting of two giant lobes. The western half, called Sputnik Planitia, is a large glacial plain packed with frozen nitrogen and other ices. The surprising amount of nitrogen on Pluto contributes to its dynamic surface features and ongoing geological and atmospheric processes, but as new research published this week in Icarus shows, it may also tell us something about where this dwarf planet came from.
