NASA's Spitzer Space Telescope discovered four new galaxies, bright red.Not yet known what caused the red color of the galaxy.
Red galaxies Spitzer found success is because of sensitivity to infrared light, which is very red-colored light up can not be seen by the eye. The newly discovered galaxy is emitting a red color which is some 60 times brighter than infrared rays.
As preached Spacedaily, Tuesday (06/12/2011), glaksi can become veryred for several reasons, namely because it is very dusty, contains many old stars that are red, or because they are in a place very far away that their light spread of natural width to a larger wavelength and red lead (redshiftingprocess). The third reason seems to apply to the galaxy.
"Hubble has shown us some of the first protogalaxies formed, but nothingthat looks like this. This could indicate that red galaxies is the 'missing link' in galaxy evolution," said Giovanni Fazio of CfA.
Furthermore, researchers hope to obtain an accurate measure of theredshifting that occurs in certain galaxies. This will require more powerfulequipment like the Large Millimeter Telescope or the Atacama LargeMillimeter Array.
They also plan to look for more examples of new species that galaxies arered.
"There is evidence of the existence of other galaxies are similar at the other side of the sky. We will analyze further through the Spitzer and Hubble, in order to track them," said Fazio
