Video: Pluto scientist’s biggest surprise so far

Scientists using the powerful Hubble Space Telescopes have identified three tiny objects at the frontier of the solar system that NASA’s New Horizons spacecraft could visit after making an historic flyby of Pluto next summer.

NASA’s New Horizons mission to Pluto and the Kuiper Belt is looking for your ideas on what to informally name its next flyby destination, a billion miles past Pluto.

The nitrogen ice glaciers on Pluto appear to carry an intriguing cargo: numerous, isolated hills that may be fragments of water ice from Pluto’s surrounding uplands. Since water ice is less dense than nitrogen-dominated ice, scientists believe these water ice hills are floating in a sea of frozen nitrogen and move over time like icebergs in Earth’s Arctic Ocean.
