Summary
This false-color image from NASA's Spitzer Space Telescope reveals hidden populations of newborn stars at the heart of the colliding "Antennae" galaxies. These two galaxies, known individually as NGC 4038 and 4039, are located around 68 million light-years away and have been merging together for about the last 800 million years. The latest Spitzer observations provide a snapshot of the tremendous burst of star formation triggered in the process of this collision, particularly at the site where the two galaxies overlap. The image was taken by Spitzer's infrared array camera and is a combination of infrared light ranging from 3.6 microns (shown in blue) to 8.0 microns (shown in red). The dust emission (red) is by far the strongest feature in this image. Starlight was systematically subtracted from the longer wavelength data (red) to enhance dust features. The two nuclei, or centers, of the merging galaxies show up as white areas, one above the other. The brightest clouds of forming stars lie in the overlap region between and left of the nuclei. Throughout the sky, astronomers have identified many of these so-called "interacting" galaxies, whose spiral discs have been stretched and distorted by their mutual gravity as they pass close to one another. The distances involved are so large that the interactions evolve on timescales comparable to geologic changes on Earth. Observations of such galaxies, combined with computer models of these collisions, show that the galaxies often become forever bound to one another, eventually merging into a single, spheroidal-shaped galaxy. Wavelengths of 3.6 microns are represented in blue, 4.5 microns in green and 5.8-8.0 microns in red. This image was taken on Dec. 24, 2003. http://photojournal.jpl.nasa.gov/catalog/PIA06853

Some galaxies are considered to be particularly striking or awe-inspiring due to their size, shape, or color. For example, the Andromeda Galaxy, which is the closest major galaxy to the Milky Way, is a beautiful spiral galaxy with a bright core and long, sweeping arms. The Sombrero Galaxy is another striking galaxy, with a distinctive hat-like shape and a bright, central bulge. The Whirlpool Galaxy is another beautiful spiral galaxy, with bright, tightly-wound spiral arms and a glowing central region.
