Very Long Baseline Array

On September 7, 2011 a group of students from Tim Edens morning electronics class along with Larry Bradley, visited the VLBA radio telescope near North Liberty.  The students were able to see the control systems that capture the information received by the radio telescope.  As you can see in several of the photos taken on that day, they were able to climb up on the dish itself for an impressive view of the sheer size of the dish (82 feet in diameter) and the surrounding Coralville reservoir and country side.

The Very Long Baseline Array (VLBA) comprises ten radio telescopes spanning 5,351 miles. It’s the world’s largest, sharpest dedicated telescope array. With an eye this sharp, you could be in Los Angeles and clearly read a street sign in New York City!

Astronomers use the continent-sized VLBA to zoom in on objects that shine brightly in radio waves, long-wavelength light that’s well below infrared on the spectrum. They observe blazars, quasars, black holes, and dying stars. They plot pulsars, exoplanets, and masers, and track spacecraft, asteroids, and planets.  More information is available at http://www.nrao.edu.
