While some galaxies are rotund and others are slender disks like our spiral Milky Way, new observations from NASA's Spitzer Space Telescope show that the Sombrero galaxy is both. The galaxy, which is a round elliptical galaxy with a thin disk embedded inside, is one of the first known to exhibit characteristics of the two different types. The findings will lead to a better understanding of galaxy evolution, a topic still poorly understood.
This August 25, 2003 NASA Spitzer Space Telescope image shows galaxy NGC 4725 --a barred spiral galaxy about 40 million light-years away in the constellation Corna Berenices. While most spiral galaxies, including the Milky Way, have... Read Post
