VERRENGIA i AP Science Writer s I'M .Astronomers using a sensi-- ; liw new instrument have lifted "a dusty veil shrouding the uni- verse to reveal galaxies forming at a furious pace much deeper in space and far earlier in time than expected. ,r pair of studies to be published today in the journal Nature describe developing starburst" galaxies observed , for the first time in patches of s space at least 11 billion from Earth. .' . The galaxies were detected indirectly, by energy emissions. iThey cannot be seen by optical telescopes because they are Mnjouflaged by dust that is Jijjracteristic of galaxies in early stages of development. Researchers say the discoveries by astronomers at the University of Edinburgh Royal Observatory in Scotland and the University of Hawaii show that sections of the deep sky that had appeared empty actually might be crammed with thousands of these bright objects, each of which might contain billions of hot, young stars. In fact, these starburst galaxies may be as common as all pf the space objects spotted by Optical telescopes. The discoveries demonstrate that astronomers may have been missing a vital, formative period in the history of the universe. The deeper astronomers peer into space, the farther back in time they are looking. It takes so long for light from a star to reach Earth that astronomers peering toward the far edges of space are seeing objects as they were billions of years ago. With potentially so many young starburst galaxies out there, astronomers may have been drastically underestimating when galaxies started forming and the rate at which they formed. Up to now, astronomers believed a peak period of galaxy formation occurred when the universe was 8 billion to 10 billion years old. (The universe is thought to be 13 billion to 15 billion years old.) But this newly observed burst of galaxy formation may have occurred much earlier perhaps when the universe was less than 2 billion years old. , light-year- tjJr "Early, rapid star formation implies that the very first objects might have had to form much earlier still."

"The question as to exactly far back in time this has taken place still has some uncertainty associated with it," said Robert Williams, director of the Space Telescope Science in Baltimore. Institute "However, the basic interpretation should be correct." Also, this stellar baby boom may have peaked at a rate five to 100 times greater than previthe estimated, ously researchers said. The findings may prompt astronomers to rewrite some early chapters in the story of the universe. "Early, rapid star formation implies that the very first objects might have had to form much earlier still," said Douglas Scott, an astronomer at the University of British Columbia.

The Royal Observatory scanned a portion of the sky known as the Hubble Deep Field. used Astronomers the Hubble Space Telescope in 1995 to zero in on that region, which was thought to be a dull cosmic neighborhood. As it turned out, the Hubble, using a regular optical telescope and other instruments, found more than 3,000 galaxies, each containing 10 billion stars. er Save 20 far-infrar- blue-tagge- d off the lowest marked price of any clearance furniture item.
