superclusters rule the tiny collection of galaxies

The cosmic bullies next door How vast superclusters rule the tiny collection of galaxies we call the Local Group  by Liz Kruesi IN 1994 astronomer Renée Kraan-Korteweg spotted some 600 galaxies lying the same distance away from us, all clustered around the constellations Hydra and Vela. These findings hinted that the region might harbor an enormous structure, perhaps a supercluster, though learning more about it would not be easy. These galaxies sit behind the Milky Way’s dense disk, which holds billions of stars and enormous clouds of dust, materials that obscure background light signals. To study what lies behind this region, aptly

Saturn in Infrared from Cassini | NASA

Saturn in Infrared from Cassini Image Credit: NASA, JPL-Caltech, SSI.   Explanation: Many details of Saturn appear clearly in infrared light. Bands of clouds show great structure, including long stretching storms. Also quite striking in infrared is the unusual hexagonal cloud pattern surrounding Saturn’s the North Pole. Each side of the dark hexagon spans roughly the width of our Earth. The hexagon’s existence was not predicted, and its origin and likely stability remain a topic of research. Saturn’s famous rings circle the planet and cast shadows below the equator. The featured image was taken by the robotic Cassini spacecraft in 2014

Goldstone Deep Space Communications | NASA/ESA

Goldstone Deep Space Communications Radar images of asteroid 2014 JO25 were obtained in the early morning hours on Tuesday, with NASA’s 70-meter (230-foot) antenna at the Goldstone Deep Space Communications Complex in California. The images reveal a peanut-shaped asteroid that rotates about once every five hours. The images have resolutions as fine as 25 feet (7.5 meters) per pixel.  “The asteroid has a contact binary structure – two lobes connected by a neck-like region,” said Shantanu Naidu, a scientist from NASA’s Jet Propulsion Laboratory in Pasadena, California, who led the Goldstone observations. “The images show flat facets, concavities and angular
