radio telescope VLA (Very Large Array) image of an interacting twin-jet radio galaxy. The two black dots (at the bottom centre) are each associated with one of the twin nuclei of a distant galaxy. The jets appear to interact and wrap around one another. Very Large Array (VLA), National Radio Astronomy Observatory, Socorro, N.M. The VLA is a group of 27 bowl-shaped radio antennas. Each antenna is 25 metres (82 feet) across. When used together, they make one very powerful radio telescope. Lovell Telescope Crab Nebula

Galaxy clusters like Abell 2744 can act as a natural cosmic lens, magnifying light from more distant, background objects through gravity. NASA's James Webb Space Telescope may be able to detect light from the first stars in the universe if they are gravitationally lensed by such clusters. (astronomy, space exploration, galaxies)
