Within a year, the world’s current largest single-dish radio telescope, the Arecibo Observatory in Puerto Rico, will lose its title. It will instead be usurped by this: the Five hundred meter Aperture Spherical Radio Telescope (FAST) in Pingtang County, China.
Astronomers in India have discovered a very unusual galaxy, and it’s dying. By now, in fact, it’s probably already dead.
Construction is well underway on what will become the world’s largest radio telescope. Once complete, the half-kilometer-wide dish will explore the origins of the Universe and scour the skies for signs of extraterrestrial intelligence.
Radio telescopes, which you may remember Jodie Foster intently listening to for signs of alien life in Contact, pluck out radio waves from far away space. Ordinary communications satellite dishes also pick up radio waves, but of manmade origin. So hmm, how easily can you convert one into another? It's totally…
Humans can only see visible light—the portion of the electromagnetic spectrum that is visible to the human eye. That's why so hard to study celestial objects hidden behind cosmic dust. But radio astronomy reveals those parts of the Universe that can't be seen in visible light—and the secrets of dust-shrouded galaxies…
With the arrival of the 54th—and final—12-meter wide radio telescope, the single largest astronomical project humanity has ever under taken can finally begin peering into the heavens at full strength.
The 13,000 square-mile National Radio Quiet Zone is home to the Green Bank Telescope. The 2-acre, 16-million pound dish is the largest, fully steerable radio telescope in the world. And, as this gorgeous video by Motherboard highlights, it might be in danger.
The visible light comprises a minuscule fraction of the entire electromagnetic spectrum. Radio telescopes allow us to observe what cannot be seen, like microwave background radiation—the echo of the Big Bang. Our friends at Oobject have assembled 18 of the most expansive intergalactic listening stations.
