A Map of the Universe

The Universe
Ever wonder how large everything is? Well, at least the known universe? People have been wondering for a long, long time about it. Some folks over at Princeton produced this map published in 2005, in the Astrophysical Journal [PDF], of the known universe.
We have produced a new conformal map of the universe illustrating recent discoveries, ranging from Kuiper belt objects in the Solar system, to the galaxies and quasars from the Sloan Digital Sky Survey. This may projection, based on the logarithm map of the complex plane, preserves shapes locally, and yet is able to display the entire range of astronomical scales from Earth's neighborhood to the cosmic microwave background. The conformal nature of the projection, preserving shapes locally, may be of particular use for analyzing large scale structure. Prominent in the map is a Sloan Great Wall of galaxies 1.37 billion light years long, 80% longer than the Great Wall discovered by Geller and Huchra and therefore the largest observed structure in the universe.
Feel small?

Civil disobedience is called for

Image
In an act of desperation, Tim DeCristopher chose civil disobedience to disrupt the bidding process that saw 149,000 acres of public land leased off to oil companies in Utah. The lease of the land to oil companies, to allow drilling, has been contested by many who wish to preserve the pristine land, located near Arches National Park, the White River, the greater Desolation Canyon region, Labyrinth Canyon, the benches east of Canyonlands National Park, Nine Mile Canyon, the Book Cliffs and the Deep Creek Mountains. It is one of the final sell-off by the dying Bush administration. DeCristopher showed at the auction, registered as a bidder, and started bidding -- and winning -- with no intention of purchasing or paying for the auctions he won. Way to go dude! You're a hero!
