A Galaxy Collision in NGC 6745 . ... Explanation: Galaxies don't normally look like this. NGC 6745 actually shows the results of two galaxies that have been colliding for only hundreds of millions of years. Just off the above digitally sharpened photograph to the lower right is the smaller galaxy, moving away. ... Although it is likely that no stars in the two galaxies directly collided , the gas, dust , and ambient magnetic fields do interact directly. ... NASA Official: Jay Norris. ...

... With a redshift of 2.3, the IRAS source FSC 10214+4724 is apparently one of the most luminous objects known in the Universe. ... The most straightforward interpretation is that FSC 10214+4724 is gravitationally lensed by the foreground elliptical galaxy, with the faint component a counterimage of the IRAS source. ... The background lensed source has an intrinsic luminosity , and remains a highly luminous quasar with an extremely large ratio of infrared to optical/ultraviolet luminosity. ...
