Latest Karl Guthe Jansky Stories
For the first time, astronomers have identified discrete sources that account for nearly all of the radio waves coming from distant galaxies.
Researchers announced Friday that they had successfully achieved "first light" at low frequencies using the Jansky Very Large Array (JVLA) radio astronomy telescope.
Two new and powerful research tools are helping astronomers gain key insights needed to transform our understanding of important processes across the breadth of astrophysics.
Radio telescopes, used in tracking and collecting data from satellites and space probes, are a form of directional radio antenna used in radio astronomy. They operate on the radio frequency portion of the electromagnetic spectrum where they detect radio sources. Radio telescopes are large parabolic antennas used singly or in an array and are located far from major centers of population in order to avoid electromagnetic interference. Karl Guthe Jansky built the first radio antenna used to...
