Pluto

New models suggest that Pluto and Charon were formed by a giant collision. This composite of enhanced color images of Pluto (lower right) and Charon (upper left) was taken by the New Horizons spacecraft as it passed through the Pluto system in 2015. Pluto and Charon are shown at approximately their relative sizes, but their true separation is not at the correct distance. Credit: NASA/JHUAPL/SwRI

How Pluto and its moon Charon were formed from a giant collision

New research reveals that Pluto and its large moon Charon formed from a unique "kiss and capture" process following a giant collision, with significant implications for understanding the solar system.
In a paper published in the journal Icarus, Alex Nguyen, a graduate student at Washington University in St. Louis, used mathematical models and images from the New Horizons spacecraft to take a closer look at the ocean that he says likely covers Pluto beneath a thick layer of nitrogen, methane and water ice.

Surprise: an ocean of liquid water on Pluto

They estimate that Pluto's ocean is, at most, about 8% denser than seawater on Earth, or about the same as the Great Salt Lake in Utah (but much less salty than the Dead Sea.

Summary of the year 2015 in science

Mountains and plains on Pluto as photographed about 15 minutes before the great approach, plus a color photograph of the same area at a lower resolution (due to the distance from which it was photographed) allow a glimpse of the spectacular views. Photo: NASA/JHUAPL/SwRI

NASA has released spectacular close-up photos of Pluto

To the right, east of Sputnik, the plain is cut by what appear to be glaciers, the sunlight illuminating the area from behind highlights over a dozen layers of haze in the thin but inflated atmosphere. The photo was taken from a distance of about 18 thousand kilometers and the width of the photographed area is 1,250 kilometers. Credits: NASA/JHUAPL/SwRI

Pluto continues to surprise and show similarities to Earth

In the center of the image, to the left of Pluto's huge route that resembles a heart shape, lies the Tombo area (named after Pluto's discoverer). It is a vast craterless plain that appears to be at most a hundred million years old and may still be shaped by geological processes. This icy region north of Pluto's ice mountains has been named the Sputnik Plain in honor of the first artificial satellite. The surface appears divided into irregular shaped segments surrounded by narrow rings. In addition, there are groups of mounds and fields of small pits in this area. This image was taken by the LORRI camera on July 14 from a distance of 77,000 kilometers. Details smaller than a kilometer can be seen. Some of my areas look raw due to the image compression.

A historic meeting

Interesting hints of Pluto's geology are revealed in this image taken by the New Horizons spacecraft on July 9, 2015 from a distance of 5.4 million kilometers from here. This annotated version of the image shows a large dark formation known as "The Whale" located on Pluto's equator, with a narrow band and elaborate polygons. In the lower part of the image is a photograph of Pluto, in which the area covered by the camera is highlighted, with the equator and the main longitude marked in bold. Photo: NASA-JHUAPL-SWRI

A whale on Pluto

This image taken on June 29, 2015 shows the large feature - most likely a crater on the underside of Pluto (the larger object). Charon also shows dark formations. The diameter of Pluto is 2,367 kilometers - about a thousand kilometers less than the Earth's moon. Charon's diameter is about 1,200 km.

Pluto inexplicably has an atmosphere, albeit a thin one, and its surface appears to be a bright peach-red color, but also areas of white and dark red. Illustration: An artist's illustration of Pluto.
