      NASA's Dawn Mission Captures New Image of Dwarf Planet Ceres

      NASA’s Dawn mission, having performed remarkably at the asteroid Vesta, is homing in on Ceres. The spacecraft’s ion engines will bring it to a capture orbit around this 590 mile diameter dwarf planet on March 6th, 2015 – at a distance some 2.5 times further from the Sun than the Earth...

      A SHARPER IMAGE

      Although only 43 pixels across, this image of Ceres’s disk as seen from 237,000 kilometers away by Dawn on January 25, 2015, was the first ever produced that surpassed the previous Hubble observations in resolution...

      PIXELATED CRATERS

      Taken on January 13, 2015, from a distance of 383,000 kilometers, this Dawn image was processed to reveal some of the first substantial details of Ceres’s craters.

      FRONT AND BACK

      A medida que se acerca a Ceres para una cita orbital el 6 de marzo, Dawn está obteniendo vistas sin precedentes de la superficie del planeta enano, como esta imagen casi completa de ambos hemisferios capturada  el 19 de febrero de 2015...

      HUBBLE’S PORTRAIT

      Tomada en 2004 por el Telescopio Espacial Hubble, esta imagen de color mejorada era el mejor retrato de Ceres antes del acercamiento de Dawn al planeta enano. Aunque borrosos, los misteriosos puntos brillantes de Ceres son visibles...

      A VIEW FROM EARTH

      Gathered by the 10-meter telescopes of the Keck Observatory in Mauna Kea, Hawaii, in 2006, infrared images of Ceres were used to assemble this rough surface map. The image is colored based on infrared brightness, with blue being the darkest and red being the brightest...

      LORD OF THE ASTEROIDS

      Ceres drifts in the mostly empty space of the Asteroid Belt in this image from February 4, 2015, captured from a distance of 145,000 kilometers. As diminutive as it may seem in this image, the 950-kilometer-wide dwarf planet is roughly the size of Texas, and represents one third of the asteroid belt’s entire mass...
