About this image

This COAST image shows the flocculent ('clumpy' or 'woolly') intermediate spiral galaxy NGC 3251. Although a spiral, the arms are not well defined and have a mottled appearance. The disk is surrounded by extensive misty-looking clouds, remnants of galaxy merger activity. Several other galaxies are visible in the image.

The galaxy was discovered in February 1784 by William Herschel.

Apparent mag. 9.0. Distance perhaps 40million ly. Age c.13.26billion yr.
