Item 2 Hubble Heritage Picture: "Polar-ring" galaxy
     Located about 130 million light-years away, galaxy NGC 4650A is one 
of only 100 known polar-ring galaxies. Their unusual disk-ring structure 
is not yet fully understood. One possibility is that polar rings are the 
remnants of collisions between two galaxies sometime in the distant 
past. During the collision the gas from a smaller galaxy was stripped 
off and captured by a larger galaxy, forming a new ring of dust, gas and 
stars, which orbit around the inner galaxy almost at right angles to the 
larger galaxy's disk.  This is the vertical polar ring, which appears 
almost edge-on in Hubble's Wide Field Planetary Camera 2 image of NGC 
4560A, created using three different color filters.
