This image is one of several NASA’s Dawn spacecraft took on approach to Ceres on 4th February 2015 at a distance of about 90,000 miles (145,000 kilometres) from the dwarf planet.

The images of Ceres were taken on 4th February 2015 from a distance of about 90,000 miles (145,000 kilometres).
At a resolution of 8.5 miles (14 kilometres) per pixel, the pictures represent the sharpest images to date of Ceres.This animation showcases a series of images obtained with the Framing Camera of NASA’s Dawn spacecraft on approach to Ceres on 4th February 2015 at a distance of about 90,000 miles (145,000 kilometres) from the dwarf planet. The resolution is 8.5 miles (14 kilometers) per pixel. Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDAAfter the spacecraft arrives and enters into orbit around the dwarf planet, it will study the intriguing world in great detail. Ceres, with a diameter of 590 miles (950 kilometres), is the largest object in the main asteroid belt, located between Mars and Jupiter.
Sprawling across Pluto’s icy landscape is an unusual geological feature that resembles a giant spider. This enhanced colour image, obtained by NASA’s New Horizons spacecraft on 14 July 2015, consists of at least six extensional fractures (arrowed) converging to a point near the centre. Curiously, the spider’s “legs” expose red deposits below Pluto’s surface.
Despite earlier reports of a possible detection, a joint analysis of data from ESA’s Planck satellite and the ground-based BICEP2 and Keck Array experiments has found no conclusive evidence of primordial gravitational waves.
Using data gathered by NASA’s New Horizons spacecraft on its Pluto flyby in July 2015, the dwarf planet has some characteristics less like that of a comet and more like much larger planets, according to the first analysis of Pluto’s unique interaction with the solar wind — the charged particles that spew off from the Sun into the solar system at a supersonic 1 million mph.
