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).
Jets of relativistic plasma created by the Supermassive Black Hole at the center of 3C 348; a galaxy in the Hercules Cluster 1000 times more massive than the Milky Way. The jets are focused beams of particles accelerated to more than half of light speed by the magnetic fields around the Black Hole. The jets extend more than a million light years into intergalactic space. This image is a combination of visible light observations by the Hubble Space Telescope and radio observations by the VLA R
