A new, slightly trippy and totally epic video released by NASA takes viewers on a flyover tour of Ceres, the largest object in the asteroid belt.
The new Ceres flyover video is an animation, but it is based on actual images and data captured by NASA's Dawn spacecraft, which has been circling the dwarf planet since March 2015. The added colors indicate the presence of various materials and the age of the surface regions — plus, they make the normally gray Ceres look just a little psychedelic.
There have been other flyover videos of Ceres produced by NASA, but none of them are quite as cinematic as this one. The video is scored like a Hollywood-produced space opera, and the producers used elegant titles to identify prominent features on the dwarf planet's surface.

The 590-mile-wide (950 kilometers) Ceres is the largest object in the asteroid belt between Mars and Jupiter. It is sometimes referred to as an asteroid but is more frequently called a dwarf planet. As a result, Dawn earned the title of first space probe to orbit a dwarf planet.
In the new video, the brownish colors on Ceres' surface indicate the presence of phyllosilicates (typically found in clay), while blue hues highlight younger regions, where the surface may have changed recently due to flows of ice or other material, as well as pits and cracks, NASA officials said.
From a distance, Ceres might look like a cold, dead hunk of space rock, but Dawn has revealed many fascinating aspects of this frozen world. As Dawn approached Ceres, its cameras picked up various shiny spots, which researchers and space fans alike were eager to identify.
Scientists now say the deposits are very likely made of hydrogen magnesium sulfate, or what's known on Earth as Epsom salt. Additional observations showed that the bright spots may be releasing volatile elements, which create a haze over part of Ceres' surface. Investigations are still underway into the composition and history of the bright spots.
The new video tour highlights some of Ceres' most prominent features, such as the tallest mountain on its surface, the roughly 4-mile-high (6.4 km) Ahuna Mons, as well as some of the dwarf planet's largest craters, including Occator crater, which contains some of the most dramatic of Ceres' bright spots.
The video was produced by "members of Dawn's framing camera team at the German Aerospace Center, DLR," according to a statement from NASA. The video was composed using images taken from August to October 2015, when Dawn was circling Ceres at an altitude of about 900 miles (1,415 km). With its thundering score and grand cinematography, it's clear that the people behind this video are excited about the work Dawn is doing.
