NASA said on Wednesday that astronomers have found the first evidence that black holes were common in the early universe. The new discovery shows that very young black holes grew more aggressively than previously thought and in tandem with the growth of their host galaxies.  NASA's Chandra X-ray Observatory was used to help make this discovery. NASA said by pointing Chandra to a patch of sky for more than six weeks, astronomers obtained the Chandra Deep Field South (CDFS).  When...

WASHINGTON, June 15, 2011 /PRNewswire-USNewswire/ -- Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe. This discovery from NASA's Chandra X-ray Observatory shows that very young black holes grew more aggressively than previously thought, in tandem with the growth of their host galaxies.

LONDON, June 14, 2011 /PRNewswire/ -- As NASA's Kepler space telescope detects hundreds of star systems with multiple planets, the search for life in the universe is firmly "on". Is Man alone, or do we have neighbours? If so, what do they look like, and where are they? The evidence may be closer than we think, according to a new book from Nottingham University Press. "From Dying Stars to the Birth of Life" by Jerry Cranford describes the new science of astrobiology...

Portrayed in movies and on television most often as gateways to another dimension or cosmic vacuum cleaners sucking up everything in sight, the misconceptions surrounding black holes are many and varied. In reality, black holes form when, at the end of their life cycle, heavy stars collapse into a supernova. After a black hole forms, it can continue to grow by absorbing its surroundings. By absorbing other stars and merging with other black holes, giant black holes -- called supermassive --...

A cataclysmic explosion of a huge star near the edge of the Universe may be the most distant object ever observed. Scientists believe the blast occurred about 520 million years after the Big Bang. This means its light has taken 13.14 billion years to reach Earth. Astronomers refer to the event, which was observed by using NASA's Swift space observatory, as GRB 090429B. The "GRB" stands for "gamma-ray burst", which is a sudden pulse of very high-energy light that the telescope is tuned to...

WASHINGTON, May 20, 2011 /PRNewswire-USNewswire/ -- An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere, has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy.

According to NASA, dark energy is driving our universe apart at an accelerated rate. Scientists performed a five-year survey of 200,000 galaxies to help add more evidence to the favored theory of how dark energy works.  This theory says dark energy works as a constant force, uniformly affecting the universe and propelling its runaway expansion.  "The action of dark energy is as if you threw a ball up in the air, and it kept speeding upward into the sky faster and faster," Chris...

A galaxy's core is a busy place, crowded with stars swarming around an enormous black hole. When galaxies collide, it gets even messier as the two black holes spiral toward each other, merging to make an even bigger gravitational monster. Once it is created, the monster goes on a rampage. The merger kicks the black hole into surrounding stars. There it finds a hearty meal, shredding and swallowing stars at a rapid clip. According to new research by Nick Stone and Avi Loeb (Harvard-Smithsonian...

WASHINGTON, April 7, 2011 /PRNewswire-USNewswire/ -- NASA's Swift satellite, Hubble Space Telescope and Chandra X-ray Observatory have teamed up to study one of the most puzzling cosmic blasts ever observed. More than a week later, high-energy radiation continues to brighten and fade from its location. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Astronomers say they have never seen such a bright, variable, high-energy, long-lasting burst before. Usually, gamma-ray bursts...

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

Xenobiology -- Xenobiology (or exobiology, or astrobiology) is the term for a speculative field within biology which considers the possibility of, and possible nature of, extraterrestrial life. It also necessarily includes the concept of artificial life, since any life form might naturally evolve elsewhere, could conceivably come out of a laboratory using a future technology. It might be difficult to tell whether a truly strange life form had in fact arisen in space, or was designed much...
