3 theories for the shape of the universe: (a) positive curvature, (b) negative curvature, and (c) zero curvature. Observations suggest that the three spatial dimensions of our universe have a flat or nearly flat geometry. The density parameter Ω0 is the ratio of the density of the universe to the critical density. By this definition Ω0= 1 for a flat universe.

NASA 4) Butterfly Nebula (NGC 6302) Located in the constellation Scorpius, the structure of this nebula is one of the most fragile and complex that has ever been studied. The butterfly shape has lead scientists to name it's structure a "bipolar structure."

Endless: This all-sky view of the entire near-infrared sky reveals the distribution of galaxies beyond the Milky Way. The image is derived from the 2MASS Extended Source Catalog, which contains more than 1.5 million galaxies, and the Point Source Catalog, which holds nearly 500 million stars within the Milky Way. The galaxies are color coded for distances obtained by various surveys. The nearest sources are blue, moderately distant sources are green, and red represents the farthest so
