Our solar system lies at the edge of a structure called the Local Arm or the Orion Spur, and according to a paper released Wednesday, Sept. 28, 2016, researchers calculated that it stretches more than 20,000 light-years long, maybe about four times what scientists had thought before.

This watering hole is the social hub of the veldt; the scrubby grasslands that stretch across Namibia. The scorched earth supports sometimes fragile populations of magnificent wildlife – from endangered predators to plentiful herds of game. But these gentle giraffes and elephants need to be careful: lions don’t sleep at night, they hunt! The spectacular starscape above southern Africa is unchanged since explorers first mapped the continent. The photographer, Pietro Olivetta from Italy, said he had to be patient to capture these shots – but it was worth the wait. (Photo by Pietro Olivetta/Caters News)





The landscape surrounding ESO's Very Large Telescope (VLT) in Chile is almost reminiscent of an alien world. The tiny silver shapes on the distant Cerro Paranal mountain are the VLT's Unit Telescopes (UTs) and smaller Auxiliary Telescopes (ATs). This image is taken from the nearby mountain that is home to another of ESO's facilities, the Visible and Infrared Survey Telescope for Astronomy (VISTA). (Photo by Y. Beletsky/ESO)
