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.
Galaxy clusters, which consist of thousands of galaxies, are important for exploring dark matter because they reside in a region where such matter is much denser than average. Scientists believe that the heavier a cluster is, the more dark matter it has in its environment. But new research suggests the connection is more complicated than that.
Far in the dwarf planet’s western hemisphere, scientists on NASA’s New Horizons mission have discovered what looks like a giant “bite mark” on Pluto’s surface. They suspect that the methane ice-rich surface on Pluto may be sublimating away into the atmosphere, exposing a layer of water-ice underneath.
Astronomers have found a dwarf planet three times farther away from the Sun than Pluto, making it the most distant known object in the solar system. Designated V774104, the body is 500 to 1000 kilometres in diameter and is currently 15.4 billion kilometres, or 103 astronomical units (AU) from the Sun, but its exact orbit is yet to be determined.
