The Very Large Array can’t image a big section of sky all at once. Instead, it must scan the sky over time. The VLA Sky Survey is using this method to create a map of nearly 80% of the observable sky. Join our host Summer Ash of the National Radio Astronomy Observatory as she talks about how the VLA is taking the time to see the big picture of the radio sky.
