Greenbelt, Md. -- A NASA telescope has found a structure in the Milky Way that may be a remnant of an eruption in a black hole at the center of our galaxy, U.S. researchers say.
The Fermi Gamma-ray Space Telescope detected the structure that spans 50,000 light years, covers half the visible sky and may be millions of years old, a NASA release said Tuesday.
"What we see are two gamma-ray-emitting bubbles that extend 25,000 light-years north and south of the galactic center," says Doug Finkbeiner, an astronomer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass.
"We don't fully understand their nature or origin," he says.

A new study on Thursday revealed that at least one in every sun-like star in the galaxy have Earth-size planets circling around them in their orbits. They added that they were able to find few Earth-like planets close to their stars only.

Paris -- French scientists say they've confirmed the most distant astronomical object known, a galaxy 13.071 billion light-years away.
The galaxy, dubbed UDFy-38135539, is so far away the light now reaching Earth left it less than 600 million years after the Big Bang, ScienceNews.org reported.
Scientists at the Observatory of Paris studied images captured by the Hubble telescope to measure the galaxy's redshift -- the extent to which light emitted by a body is shifted to longer, or redder, wavelengths by the expansion of the universe -- to determine its distance.
The more distant a body, the greater its redshift.

Verizon has defended the price of $600 for Samsung Galaxy reminding that no service contract is required for the buyers. The phone, equipped with 3G cellular service and Wi-Fi will be available from 11th of November. Otherwise Verizon and other service providers the customers to sign a two year contract for purchasing a smart phone.

Paris -- French scientists say they've confirmed the most distant astronomical object known, a galaxy 13.071 billion light years away.

Pasadena, Calif. -- A distant galaxy with a tail studded with bright clumps of new stars offers clues to how such stars form, U.S. researchers say.
Galaxy IC 3418's tail was formed as it collided with the neighboring Virgo cluster of galaxies, ScienceDaily.com reported Wednesday.
"The gas in this galaxy is being blown back into a turbulent wake," said Janice Hester of the California Institute of Technology in Pasadena.
"The gas is like sand caught up by a stiff wind," she said. "However, the particular type of gas that is needed to make stars is heavier, like pebbles, and can't be blown out of the galaxy.
"Observations are teaching us that this heavier, star-forming gas can form in the wake, possibly in swirling eddies of gas."

University Park, Pa. -- A mysterious cloud is forming stars at a furious rate inside one of the galaxy's colossal nebula, Pennsylvania State University researchers said.
A wave of massive star formation appears ready to begin within the dark cloud, named M17 SWex, in the Milky Way, the University Park, Pa., institution said Wednesday in a release. The dark cloud is part of the larger nebula known as M17, a region of the galaxy with a bright, central star cluster.
"We believe we've managed to observe this dark cloud in a very early phase of star formation before its most massive stars have ignited," said Penn State astronomer Matthew Povich, a post-doctoral fellow and the lead author of a study published recently in The Astrophysical Journal Letters.

Tokyo -- A team of scientists from Japan and Taiwan says it has uncovered details explaining the growth of galaxy clusters.
Researchers from Tokyo's Riken Institute and the Academia Sinica Institute of Astronomy and Astrophysics in Taipei said their discovery concerning galaxy clusters -- the largest gravitationally bound objects known to exist -- offers new clues about the evolution of our universe.
The scientists said they studied galaxy clusters using Suzaku, an X-ray astronomical satellite developed in Japan, and compared that data with the U.S. Sloan Digital Sky Survey, a spectroscopic survey by the Apache Point Observatory in New Mexico.

New York, January 6 -- NASA’s Hubble telescope gave astronomers the first look of the youngest galaxies formed 600 million years after the Big Bang, which is thought to have taken place some 13.7 billion years ago.
