"A Hubble Space Telescope image shows unprecedented detail of the Antennae galaxies, an intense star-forming region created when two galaxies began to collide some 200 million to 300 million years ago. The bright, blue-white areas show newly formed stars surrounded by clouds of hydrogen, which are colored pink. A similar collision is expected between our galaxy, the Milky Way, and the nearby Andromeda galaxy in several billion years." via National Geographic

Antennae Galaxies... One of the most spectacular galactic mergers is known as the Antennae galaxies. Located about 62 million light-years away in the constellation Corvus, the object contains a jewelry case of stars that shine in the visible, infrared, and X-ray wavelengths in this image. The colliding galaxies have nearly engulfed one another since they first began to unite around 100 million years ago, triggering an intense period of star formation.
