Most Detailed Images of Pluto Since Hesiod



"Hades [Pluto] trembled where he rules over the dead below, and the Titans under Tartarus who live with Cronos [Saturn] ...." -- Hesiod, poet, Theogony, 8th century B.C.

"After the capture of Elis he [Mars] marched against Pylus and having taken the city he slew Periclymenus, the most valiant of the sons of Neleus, who used to change his shape in battle. And he slew Neleus and his sons, except Nestor; for he was a youth and was being brought up among the Gerenians. In the fight he also wounded Hades [Pluto], who was siding with the Pylians." -- Apollodoros, historian, The Library, Book II, 2nd century B.C.

Science Daily: New Hubble Maps of Pluto Show Surface Changes.

The images taken by NASA's Hubble Space Telescope show an icy and dark molasses-colored, mottled world that is undergoing seasonal changes in its surface color and brightness.

Methane On Pluto



There must be a lot of cows, cyanobacteria, and dinosaurs living on Pluto to produce all this biogenic fossil fuel: The lower atmosphere of Pluto revealed.

Using ESO's Very Large Telescope, astronomers have gained valuable new insights about the atmosphere of the dwarf planet Pluto. The scientists found unexpectedly large amounts of methane in the atmosphere, and also discovered that the atmosphere is hotter than the surface by about 40 degrees, although it still only reaches a frigid minus 180 degrees Celsius. These properties of Pluto's atmosphere may be due to the presence of pure methane patches or of a methane-rich layer covering the dwarf planet's surface.

"With lots of methane in the atmosphere, it becomes clear why Pluto's atmosphere is so warm," says Emmanuel Lellouch, lead author of the paper reporting the results.
