Very Large Array
NASA Visualizes Massive Radio Wave Output Of Hercules A GalaxyGalaxies are a lot like people -- some are notable for their shape, or their age, or their brightness, but others you can only notice how very, very loud they are. These radio galaxies emit vast quantities of energy on radio wavelengths, and Hercules A is among the loudest we know of, with the supermassive black hole at it's center putting out about a billion times more energy along radio wavelengths than the Sun. Now, courtesy of a collaboration between the Hubble Space Telescope and the Very Large Array (VLA) radio telescope, we can visualize what all that energy would look like and, well, it's pretty serious stuff. For a look at how the visualization took shape, you can check out the video below.Read on...
Beautiful Time Lapse Film Captures the Very Large Array as It Scans the SkiesFor those unaware, the Very Large Array is a collection of radio telescopes out in the desert near Socorro, New Mexico. With it, scientists are able to probe the edges of the universe, and witness amazing sites invisible to the eye. It was also a critical set piece in the film Contact, and what's more, the sight of all those radio antennas pointing skyward is more than a little iconic. Using time lapse photography and motion graphics, film maker Douglas Koke lets the amazing telescopes take center stage in his short film Signal to Noise. It's a pretty amazing look at an astounding piece of human ingenuity.Read on...
