The Two Faces of Phoebe

February 13, 2014

Cassini flew past Phoebe on June 11, 2004, on its way to entering Saturn orbit. The flyby was almost perfect but overexposure of some images have prevented color mosaics from being produced.

A montage of 18 of the 20 asteroids and comets that have been photographed up close as of December 2018, when New Horizons flew past Arrokoth. This version is in color but does not show the bodies at their correct relative albedo or brightness. Not included are Vesta or Ceres, both of which are many times larger than Lutetia.

South Pole of Neptune

As Voyager 2 flew past Neptune, it saw high, white clouds swirling around a faint vortex at the planet’s south pole. The clouds cast shadows on the blue atmosphere below. The serene faces of the solar system’s ice giants mask high-speed winds in atmospheres as dynamic as those of Saturn and Jupiter.
