Bar in Space

Number 95 in Messier's catalog, a galaxy about 33 million light years distant. I took this image with an 180 mm aperture robotic telescope in New Mexico. My thanks to the Tzec Maun Observatory.

This image was taken by Michael McGuiggan and Adam Block, from the National Optical Astronomy Observatory, with a 20 inch telescope. Here is another image taken with a larger instrument.

Why many galaxies show bars, and a ring surrounding the bar, has not been fully explained yet.
