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. Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDANASA’s Dawn spacecraft, on approach to dwarf planet Ceres, has acquired its latest and closest-yet snapshots of this mysterious world. 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.
The Moon’s Orientale basin is an archetype of “multi-ring” basins found throughout the solar system. New research has enabled scientists to reconstruct Orientale’s formation using data from NASA’s GRAIL mission. It is now thought that the 580-mile-wide feature was created 3.8 billion years ago by an impacting object some 40 miles across travelling at about 9 miles per second.
Astronomers were watching when comet P/2016 BA14 flew close by Earth on 22 March at a distance of slightly more than nine times the distance of the Moon. Radar images from the flyby indicate that the body is about a kilometre in diameter, while infrared spectra indicate that the comet’s nucleus is as dark as fresh asphalt.
This feature appears to be a frozen, former lake of liquid nitrogen, located in a mountain range just north of Pluto’s informally named Sputnik Planum. Captured by the New Horizons’ Long Range Reconnaissance Imager (LORRI) as the spacecraft flew past Pluto on 14 July 2015, the image shows the possible lake to be about 20 miles (30 kilometres) across.
