A beautiful new image of two colliding galaxies has been released by NASA's Great Observatories. The Antennae galaxies, located about 62 million light-years from Earth, are shown in this composite image from the Chandra X-ray Observatory (blue), the Hubble Space Telescope (gold and brown), and the Spitzer Space Telescope (red).
Arp 147 galaxies - This image of the two galaxies that form Arp 147 shows a vast cosmic ring of stars (blue) and black holes (pink) as seen by the Chandra X-ray Observatory and Hubble Space Telescope. Another galaxy is also visible (vertical at left), as well as a bright star and quasar (pink object at upper left). Credit: NASA/CXC/MIT/S.Rappaport et al, Optical: NASA/STScI
