This Hubble Space Telescope image, and one from the European Southern Observatory, provide two views of a pair of galaxies that appear to be smashing into each other in a cosmic collision. But don’t be fooled. The face-on spiral galaxy is actually about 117 million light years from Earth while other is some 140 million light years away. They appear to be colliding thanks to a chance alignment when viewed from Earth. In the wider-angle ESO view below Hubble’s stunning close up, a dim, yellowish smudge can be seen toward the lower right, an ultra-diffuse galaxy and one of the faintest in the Hydra I galaxy cluster. UDG are extremely faint and lack the star forming gas of galaxy’s like the Milky way.
