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.
Craters with bright material on dwarf planet Ceres shine in new images from NASA’s Dawn mission taken from its lowest-altitude mapping orbit. Young crater Haulani (diameter 21 miles) and 6-mile-wide Oxo Crater — the second-brightest feature on Ceres — provide scientists with insight into the dwarf planet’s materials and surface morphology.
The European Space Agency’s orbiting XMM-Newton X-ray observatory has proved the existence of a ‘gravitational vortex’ around a black hole. The discovery, aided by NASA’s NuSTAR mission, solves a mystery that has eluded astronomers for more than 30 years and will allow them to map the behaviour of matter very close to black holes.
During the month of December, the Planetary Radar Group at Arecibo Observatory has observed near-Earth asteroid 2003 SD220, which will make its closest approach to Earth on Christmas Eve. Although designated as “potentially hazardous,” this asteroid will be 28 times further away than our Moon and therefore poses no present danger to Earth.
