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.

ALMA reveals secrets of the most luminous known galaxy
The most luminous galaxy known in the universe — the quasar W2246-0526, seen when the universe was less than 10 percent of its current age — is so turbulent that it is in the process of ejecting its entire supply of star-forming gas, according to new observations with the Atacama Large Millimetre/submillimetre Array (ALMA).
Best ever image of another star’s surface and atmosphere
Using ESO’s Very Large Telescope Interferometer astronomers have constructed the most detailed image ever of a star — the red supergiant star Antares. They have also made the first map of the velocities of material in the atmosphere of a star other than the Sun, revealing unexpected turbulence in Antares’s huge extended atmosphere.
