Galaxy M91 in Coma Berenices

M91 is one of the "missing" Messier Objects. Cartes de Ciel indicates that this object, a barred spiral galaxu is that object. Again, this is part of the Virgo-Coma Berenices cluster. This galaxy lies at a distance of 41 million light years and has a diameter of 60,000 light years. As stated above, this galaxy is part of the Virgo cluster, If you put your mouse over this figure, you will see M88 in relation to M91. If you then hold the mouse button down, you will see a large part of this cluster. M88 is the galaxy in the lower left while M87 is the galaxy in the lower right of this image and M84 and M86 are in the upper right. M100 can be seen in the upper left of the rollover image. (Note, the rollover image is flipped from the other two.)
