NGC4038

This slow pan across the Antennae Galaxies is based on an image from the NASA/ESA Hubble Space Telescope, which shows the stars in this pair of colliding galaxies, including the bluish hot young stars. Superimposed on this is a new image from ALMA that shows a totally new view of the Antennae, revealing in greater detail than ever before the clouds of dense cold gas from which new stars form.
