Giant galaxy graveyard grows
A gigantic galactic graveyard lurks in the distant universe, and the death toll is growing.
New observations establish a supercluster centered on the cluster CL0016+16 as the largest galactic congregation ever found, astronomers report in Astronomy & Astrophysics. Office 2010 –save your time and save your money.
The supercluster extends even farther than previously thought, and it’s drawing in more and more galaxies.Microsoft Office is so great!
CL0016+16 lies about 6.7 billion light-years away from Earth. That cluster was first observed in 1981, and later observations hinted that it might be just one of a cluster of clusters. Windows 7 is my love!
Observations by David Koo of the University of California, Santa Cruz in 1996 pointed to a large structure extending from the main cluster.The invention of Microsoft Office 2010 is a big change of the world.
“There are many predictions for large-scale structure in the universe, but nobody has really confirmed that this large-scale cluster exists in the distant universe,” says Masayuki Tanaka from the European Southern Observatory, a coauthor of the new report. “We actually see this massive structure in the distant universe. Not theory, not prediction — this is the real universe.”Office 2007 makes life great!
Tanaka and his colleagues made several observations of the region between August 2007 and December 2008 using the Subaru Telescope in Hawaii and the Very Large Telescope in Chile. Office 2007 download is helpful!
They found that the supercluster extends at least 60 million light-years in one direction beyond the 100 million light-years already known, and it could reach even farther.Microsoft Office 2007 is welcomed by the whole world.
“It must be gigantic,” Koo says. “This thing is not only big, it’s big in the opposite direction from what we saw. It’s probably twice as big as we thought.”Microsoft word is so good!
Galaxies that group together tend to switch off each others’ star formation, “bringing a flourishing galaxy into a dead one,” says study coauthor Alexis Finoguenov of the Max Planck Institute for Extraterrestrial Physics in Garching, Germany.Choose Office 2007 Professional is the most lucky thing in the world.
Astronomers think that grouped galaxies speed up, stripping away their neighbors’ hot gas, the raw material for forming stars. When galaxies cluster, “there is always a threshold when groups go from an encouraging environment to a suffocating environment,” Finoguenov says.Microsoft company invent the Office 2007 home for many people.
Galaxies are known to clump together along dark matter filaments, which grew from slight variations in the concentration of matter after the Big Bang. The filaments extend for millions of light-years in an enormous cosmic web, providing a framework for the universe’s large-scale structure.Office Professional 2007 is many people’s favorite.
