I enjoy creating color images from three grayscale images. The post linked here will explain how to create color astronomical images. The colors assigned are not necessarily what the human eye would see, but are used to bring out details. Visit the gallery of previous Astro-Images. Unless otherwise noted, all images are made by me using three original grayscales from the Hubble Legacy Archive.
This is the first of three examples of galaxies viewed edge-on. Each shows the dust in the plane of the galactic disk which absorbs light from the stars behind. Also known as the Needle because of its thin appearance, this Hubble image is quite enlarged to show detail. It is found in the constellation Coma Berenices of the northern skies.

Located in the constellation Ursa Major, this galaxy would look very circular and very similar to our Milky Way if viewed from above. Our Milky Way would look this way seen edge-on. The very bright star near the center looks like it is part of the galaxy. Actually, it is not. It is one of the stars of our Milky Way that happens to be in the foreground.
Nearly 60 million light years away in the constellation Canes Venatici, this spiral galaxy shows some bright knots of star formation regions within the dust lane. Also, bright glow of billions of stars in the galactic core is obvious in the upper left. Several other very small and faint galaxies are visible as tiny smudges or the vertical streak at the right. These galaxies are very much farther away than NGC 4217.
