Stellar region nearly empty of galaxies

As any casual stargazer would predict, the distribution of stars and galaxies in the universe is not uniform. Certain regions in space hold clumps and clusters of these objects, and others are relatively empty.

But even astronomers are surprised by new findings from three observatories that show just how uneven the distribution of galaxies is. A team of astronomers has found a huge region near the North Star that is nearly empty of visible galaxies, It covers 30¡Æto 40¡Æof the sky and takes up about 1£¥ of the entire observable universe. In fact, it's large enough to hold about 2,000 galaxies the size of the Milky Way.

The investigators are Robert Kirshner of the University on Michigan, Augustus Oemler Jr. of Yale University, Paul L. Schechter of Kitt Peak National Observatory, Arizona, and Stephen A. Shectman of Carnegie Instruction's Mount Wilson, Calif., and Las Campanas, Chile, observatories. The region they have discovered includes part of the constellation Bootes and is in the same area of the sky as the handle of the Big Dipper.

"To have found a population density of less than three times the average would have been a rare find." Schechter says. "But finding that the density is about 10 times less than the average is exceedingly hard to understand."

The region puzzles Schechter and other astronomers because most of them accept the theory that the density of galaxies was fairly uniform just after the great explosion, or "big bang," that started the universe 10 billion to 20 billion years ago. Building from such a fairly uniform distribution, they had not predicted that such a vast region of space would be so empty.
