"Fossil" Spiral Galaxy M90 in Virgo
Spiral Galaxy M90, also called NGC 4569, is near the center of the Virgo Cluster of Galaxies, at a distance of 60 million light years.  Unlike most other galaxies, M90
has a blueshift of its light, showing that is is moving towards us and not away from us.  This is because of its motion within the VIrgo Cluster, which as a group is moving
away from us, with most of its galaxies showing a redshift. The smooth spiral arms lack star formation, placing it in the category of a "fossil" galaxy. Compare this image to

one obtained 15 years earlier at one of the world's premier observatories
...an Astronomy Picture of the Day back then.

This image combined 44 minutges of clear luminance exposures unbinned, with 24 minutes of red, 24 minutes green and 32 minutes of blue exposures, binned 2x2.  Total
exposure time was 2 hours 4 minutes.  A QSI-583wsg camera was used through a 12" Astro-Physics Ricardi-Honders Astrograph at f3.8.
