China is Relocating 9000 People to Build the World’s Largest Radio Telescope

This past summer, China began construction on the world's largest and most sensitive radio telescope. When completed, the 500-meter (1640-foot) Aperture Spherical Radio Telescope (or FAST) will stretch more than 600 feet wider than the previous record-holder, the Arecibo Observatory, in Puerto Rico. According to Al Jazeera, officials in the country’s Guizhou province have announced that 9110 residents will be relocated to make way for the massive structure.

In order to ensure the telescope functions as accurately as possible, anyone living within about a 3-mile radius of the device is being moved to create a "sound electromagnetic wave environment for the machine," Al Jazeera cites the Xinhua News Agency (China's government-sponsored press agency) as reporting. The affected citizens will reportedly be given about $1800 each as compensation and will be moved from the area by September.

A telescope this powerful could be used by astronomers to survey the cosmos for undiscovered galaxies, exoplanets, and faint pulsars. According to Wu Xiangping, the director-general of the Chinese Astronomical Society, as quoted by Xinhua, FAST will also be used to search for intelligent alien life beyond our own galaxy. You can check out the video above for drone footage of the partially constructed telescope taken this past fall.

After weeks of mailing out this year’s holiday cards, postage might be the last thing you want to think about. But the U.S. Postal Service has just given us a sneak peek at the many iconic people, places, and things that will be commemorated with their own stamps in 2018, and one in particular has us excited to send out a few birthday cards: Mister Rogers.

In celebration of the 50th anniversary of Mister Rogers’ Neighborhood, Fred Rogers’s groundbreaking PBS series that the USPS says “inspired and educated young viewers with warmth, sensitivity, and honesty,” the mail service shared a mockup of what the final stamp may look like. On it, Rogers—decked out in one of his trademark colorful cardigans (all of which were hand-knitted by his mom, by the way)—smiles for the camera alongside King Friday XIII, ruler of the Neighborhood of Make-Believe.

Though no official release date for Fred’s forever stamp has been given, Mister Rogers is just one of many legendary figures whose visages will grace a piece of postage in 2018. Singer/activist Lena Horne will be the 41st figure to appear as part of the USPS’s Black Heritage series, while former Beatle John Lennon will be the face of the newest Music Icons collection. Sally Ride, the first American woman in space, will also be honored.
