Description

This object is an edge-on galaxy located 150 million light years away in the constellation of Bootes. 

Viewed from almost exactly edge-on, it has a bright core with a dark dust lane running through the center. No central bulge is visible. The core is yellow and the arms are blue, likely reflecting the ages of the stars in each region. This galaxy is a large one, estimated at twice the size of our Milky Way. But it has a very thin disk - the galaxy is almost 10 times longer than it is wide. Most interestingly, the disk is warped at the left edge, likely from a gravitational interaction with a nearby galaxy.

Which brings us to the other smaller (<1 minute) galaxies in this image.  Highlighting a few of my favorites:

- The faint galaxy, PGC 50925, is slightly above and left of NGC 5529. It looks like a dwarf galaxy, fairly circular but with an interesting dark patch above the center. No core is seen in this bluish, somewhat spherical shape.

- The brighter blue galaxy, PGC 50952, is slightly above and to the right of NGC 5529. It looks like a face-on, blue, flocculent spiral galaxy with many clusters in the outer region.

- The only other galaxy in this image with an NGC designation, NGC 5527, is the bright galaxy at the lower left of the image. This galaxy is nearly face-on to us and has a strong dust lane spiraling out of its core.

- At the bottom of the image, on the left side, is PGC 50902. This blue galaxy has a fascinating structure. It almost seems like an elliptical galaxy, but there are numerous star clusters present so perhaps it is just another beautiful irregular galaxy.

- At the bottom of the image, slightly left of center, is a grouping of three interesting irregular blue galaxies (PGC designations 2080090, 2080196, and 50944). My favorite is the left most galaxy, a spiral galaxy with three distinct arms.

- Finally, my favorite galaxy in the image is the interacting pair of galaxies (PGC 2076843) lower right of center. Two bright yellowish cores are seen, with the left core encircled by several graceful looping star streams. This reminds me of the Antennae Galaxies, although the star streams are not symmetric in this object.

Many other small galaxies also fill the image background.
