The footprint of the former Lake on Pluto?

Whether in the past on the surface of Pluto is a Lake of liquid? One of the latest images from the New Horizons that is what suggests.July 14, 2015 the spacecraft New Horizons (NH) flew next to Pluto. Eyes of researchers released an incredible dwarf planet with very heterogeneous surface, providing for different periods of geological activity. Within a few days after the flight the spacecraft sent only 5% of all collected data. A month and a half later began a more regular down-link, poll has still on transfer with about half of the data. This will take at least several months, therefore, from time to time, as the flow of information, NASA Announces new findings on Pluto and its moons.

The latest discovery suggests that, in the past, Plutonium was denser atmosphere. The atmospheric pressure was large enough to allow some of the liquid to keep up for long periods of time on the surface of Pluto. Part of this liquid would like in formation that looks today like a frozen lake.

In addition, the new interpretation of the obtained images of the small moons of Pluto suggests that these objects were formed as a result of the collision, and are not secondary objects in the Kuiper belt. This indicates the measurement of the albedo of the small moons of Pluto, which is considerably higher than the objects in the Kuiper belt. The higher albedo suggests the presence of water ice.

The rise of small moons probably owe a large collision, which occurred after the formation of the like Pluto and Charon. As a result of the collision near Pluto was a large amount of matter, from which eventually created small moons.
