For Release: September 7, 2004

Interacting Antennae GalaxiesThis false-color image from NASA's Spitzer Space Telescoperevealshidden populations of newborn stars at the heart of the colliding"Antennae"galaxies. The main image is a false-color composite of infrared data(red)from Spitzer and visible-light data (blue, green) from Kitt PeakNationalObservatory, Tucson, Ariz. The upper right panel shows the Spitzer imagebyitself, using infrared light at wavelengths ranging from 3.6 microns(shownin blue) to 8.0 microns (shown in red). The lower right panel shows thetrue-color, visible-light image by itself.

artist's conception of starbirthThis artist's conception shows a hidden population of new starsthat the Spitzer Space Telescope spotted inside a dark storm of dustthatblankets the heart of the merging Antennae galaxies. Several billionyearsfrom now, our home might look the same as the Andromeda galaxy smashesintothe Milky Way like a bulldozer through a condemned building.Credit: David A. Aguilar (CfA)
