NGC 6872 and IC 4970 are a set of interacting galaxies approximately 300 million light-years away in the constellation Pavo.
On March 29, 1999, the European Southern Observatory (ESO) took a look at these galaxies. It shows the spectacular barred spiral galaxy NGC 6872 that is shaped like an "integral sign". It is of type SBb and is accompanied by a smaller, interacting galaxy, IC 4970 of type E7-S0.[citation needed]
One of NGC 6872 spiral arms is significantly disturbed and is populated by a plethora of blueish objects, many of which are star-forming regions. This may have been be caused by a recent passage of IC 4970 through it. The whole galaxies extends over more than 7 arcmin in the sky and its real size from tip to tip is thus nearly 750,000 light-years. It is in fact one of the largest known, barred spiral galaxies.
