What We Do

The National Radio Astronomy Observatory designs, builds and operates the world's most sophisticated and advanced radio telescopes. Scientists from around the world use these powerful tools to study the Sun, planets and other objects in our own solar system, as well as distant stars, galaxies, and other mysterious objects many millions, or even billions of light-years away.

[Movie] Watch a short video trailer (Quicktime format) to follow the delivery of the first ALMA production antenna from the VertexRSI facility in Kilgore, TX through the port of Houston to the ALMA Operations Support Facility in northern Chile: small (1.1 MB), medium (15 MB), large (69 MB).
 

Radio Astronomy Contributions to Technology and National Competitiveness

Radio Astronomy Competitiveness Radio astronomy is a national resource that contributes to American competitiveness and drives progress in key technologies. Technical innovations developed or enhanced for radio astronomy are found in communication antennas, transistor design, cryogenic coolers, medical and scientific imaging, time and frequency standards, atomic clocks and GPS navigation, precision spacecraft navigation, laser rangefinders, and location of cell phone 911 calls.
