You Are Here (On Earth)

Anonymous Coward writes "NY Times today has an essay about a map of the entire universe produced by two Princeton astronomers using a variety of data including the Sloan Digital Sky Survey. Its view begins with the Earth at the bottom and extends back almost to the Big Bang at the top, including such objects as the Sloan Great Wall, 1.37 billion light-years long. The map can be found here."

There is no such thing as a good lie.

There is, however, such a thing as a good model, as any true scientist will tell you. Obviously, the only perfect model of the universe is the universe itself; however, the derivation of useful models which are by design imperfect is absolutely at the heart of science.

Location and orbit of WMAP

[Morgaine]

LOL, that post made the Wilkinson Microwave Anisotropy Probe (WMAP) sound like a secretive spy satellite. :-)

Actually, WMAP is a hugely successful astronomical microwave observatory which sits at Earth's second Lagrange Point (L2). L2 is 1.5 million kilometers on the opposite side of the Earth from the Sun. This informative page shows the location and how the probe got there very clearly.

The WMAP was launched in June of 2001 and has made a map of the temperature fluctuations of the Cosmic Microwave Background (CMB) radiation with much higher resolution, sensitivity, and accuracy than its predecessor, COBE. It has been a huge success.
