   Explanation: Get out your red/blue glasses and float next to Helene,
   small, icy moon of Saturn. Appropriately named, Helene is a Trojan
   moon, so called because it orbits at a Lagrange point. A Lagrange point
   is a gravitationally stable position near two massive bodies, in this
   case Saturn and larger moon Dione. In fact, irregularly shaped ( about
   36 by 32 by 30 kilometers) Helene orbits at Dione's leading Lagrange
   point while brotherly ice moon Polydeuces follows at Dione's trailing
   Lagrange point. The sharp stereo anaglyph was constructed from two
   Cassini images captured during a close flyby in 2011. It shows part of
   the Saturn-facing hemisphere of Helene mottled with craters and
   gully-like features.
