ESO 269-57 (also known as LEDA 45683) is a barred spiral galaxy approximately 155 million light-years away in the constellation Centaurus. It is a member of a well-known cluster of galaxies seen in this direction. The galaxy received this designation when it was catalogued during the first European Southern Observatory (ESO) Survey of the Southern Sky in the 1970's.
In April 1999, the European Southern Observatory (ESO) took a look at ESO 269-57 and shows the complex structure of it, with an inner "ring", of several tightly wound spiral arms, surrounded by two outer ones that appear to split into several branches. Many blue and diffuse objects are visible - most are star-forming regions. The velocity is just over 3100 km/s, indicating the distance. It extends over about 4 arcmin in the sky, corresponding to nearly 200,000 light-years across.
