Description
This delicate smudge in deep space is far more turbulent than it first appears. Known as IRAS 14348-1447, this celestial object is actually a combination of two gas-rich spiral galaxies. The two approached each other too closely in the past, gravity causing them to affect and tug at each other and slowly, destructively, merge into one. IRAS 14348-1447 is located over a billion light-years away from us. It is one of the most gas-rich examples known of an ultraluminous infrared galaxy, a class of cosmic objects that shine brightly in the infrared part of the spectrum.
