Giant Radio Telescope Sees Inside Galactic Smash-Up
A radio telescope array being built in the highest, driest desert in the world has photographed two colliding galaxies for its first public-test shots. The new images reveal a flurry of star formation within thick clouds of gas and dust at the Antennae Galaxies' impact zone, 45 million light-years away.
A 100-ton ALMA radio telescope antenna. Working together, a spread-out array of antennas can peer farther and with more sensitivity than a single antenna alone.
