[ statistics ] The Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects. The target object, Dimorphos, is a 160-meter-long (525-foot) minor-planet moon of the asteroid Didymos. DART was launched on 24 November 2021 and successfully collided with Dimorphos on 26 September 2022 while about 11 million kilometers (6.8 million miles) from Earth. The collision shortened Dimorphos's orbit by 32 minutes and was mostly achieved by the momentum transfer associated with the recoil of the ejected debris, which was larger than the impact. This video is a timelapse of DART's final five and a half minutes before impacting Dimorphos, and was compiled from photographs captured by the Didymos Reconnaissance and Asteroid Camera for Optical navigation (DRACO), the spacecraft's 20-centimeter-aperture (7.9-inch) camera, and transmitted to Earth in real time. The replay is ten times faster than reality, except for the last six images, which are shown at the same rate at which the spacecraft returned them. Both Didymos and Dimorphos are visible at the start of the video, and the final frame shows a patch of Dimorphos's surface 16 meters (51 feet) across. DART's impact occurred during transmission of the final image, resulting in a partial frame.Video credit: NASA / Johns Hopkins APL

Wikimedia Commons Picture of the day The Scroll of Eighty-Seven Immortals, drawn by an unknown painter, measuring 30cm high and 292cm wide, is a line-drawing Chinese figure painting. Drawn on a long silk scroll with lines, the painting depicts 87 taoist immortals, including three supreme gods with halo, ten divine generals, seven deities and 67 celestial maidens marching from the right to the left on the bridge. The painting manifests the momentum of the glorious age of Tang Dynasty and was regarded by Xu Beihong as a work of Wu Daozi. Xie Zhiliu ang Chang Dai-chien thought that the painting style of the scroll was simlilar to that in Dung Huang frescoes of later Tang Dynasty and attributed it to Later Tang Dynasty (923–937), while a noted painting and calligraphy connoisseur, Xu Bangda, thought it should be drawn by a Southern Song dynasty (1127–1279) painter.
