More examples of my attempts to make color astronomical images from three filtered greyscale ones. More details in this previous post. Click to embiggen images..
Known as a barred spiral, the bright center bar of the galaxy has four spiral arms that extend outward from the ends. The spiral arms also contain bright star formation regions. Link to the APoD version from Hubble.
There are two star formation regions in this image. The larger one with many stars is about 50 million years old which is quite young from a cosmic point of view. The smaller and brighter cluster near the bottom is only 4 million years old. Stars of different age and temperature emit different colors. Link to the APoD version from Hubble.
Most people know of the great constellation Orion, the Hunter. Three bright stars in a row form his belt. Hanging from the belt are three more making up his sword. The middle star is also known as the location of the Orion Nebula, or m42. It is a large region of glowing gas and star formation. This image is from only a part of that nebula toward the lower right of the broader view in the APoD link from Hubble.
