Two new moons for Pluto

Pluto, the most distant planet in our Solar System, has been known for nearly 30 years to have a moon – Charon – although some scientists suspected it may have other, smaller moons. Now, Nature reports the discovery of two new moons orbiting Pluto and presents streaming video of lead scientist Hal Weaver and News & Views author Richard Binzel discussing how they were found using the Hubble Space Telescope — and how a giant impact could explain their origin.
