Missing Mass: Lone Wolf Planets Outnumber Milky Way Stars
2012-05-11 03:16:53

Researchers say life-bearing planets may exist in vast numbers in the space between stars in the Milky Way A few hundred thousand billion free-floating life-bearing Earth-sized planets may exist in the space between stars in the Milky Way. So argues an international team of scientists led by Professor Chandra Wickramasinghe, Director of the Buckingham Centre for Astrobiology at the University of Buckingham, UK. Their findings are published online in the Springer journal Astrophysics and...

Is The Possibly Of New Life Forms Really So Alien?
2012-05-09 07:44:18

The idea of discovering a new form of life has not only excited astronomers and astrobiologists for decades, but also the wider public. The notion that we are the only example of a successful life form in the galaxy has, for many, seemed like an unlikely statistic, as we discover more and more habitable planetary bodies and hear yet more evidence of life's ability to survive in extreme conditions. A new essay, published May 8 in the online, open-access journal PLoS Biology, examines what...

Image 1 - Milky Way’s Companions May Spell Trouble For Dark Matter
2012-04-25 07:46:27

Astronomers from the University of Bonn in Germany have discovered a vast structure of satellite galaxies and clusters of stars surrounding our Galaxy, stretching out across a million light years. The work challenges the existence of dark matter, part of the standard model for the evolution of the universe. PhD student and lead author Marcel Pawlowski reports the team´s findings in a paper in the journal Monthly Notices of the Royal Astronomical Society. The Milky Way, the galaxy we...

CHICAGO, April 23, 2012 /PRNewswire-USNewswire/ -- On May 25, 2012, take a mind-blowing tour of the Universe like no other at the Adler Planetarium. Welcome to the Universe is the next adventure departing from the Grainger Sky Theater, the most technologically advanced theater in the world. In Welcome to the Universe, audiences travel a billion light-years and back flying through space, orbiting the Moon, zooming into a canyon on Mars, and soaring through the cosmic web where a million...

Earth Day 2012 – How Will You Show The Love?
2012-04-20 14:02:44

Lee Rannals for RedOrbit.com Whether you're of a religious background and support the idea of creation, or prefer more scientific theology and put your faith in the theory of evolution, one thing remains certain amongst all: Our Earth has been beautifully made. Other planets in our Solar System are bleak and subdued compared to our planet, lacking an ample supply of brilliant colors, and the right conditions to support life. We have a range of geology here on Earth, such as mountain...

Robots Required In Hunt For ET, Engineer Suggests
2012-04-19 06:09:00

A Penn State engineer suggests that finding and identifying extraterrestrial life may require a big leap in robotics. John D. Mathews, professor of electrical engineering, wrote in the current issue of the Journal of the British Interplanetary Society that if there are aliens out there, they may not be eager to meet humans. He said that only by developing self-replicating robotic spacecraft would the human race be capable of efficiently exploring the vastness of the universe. "If...

What Fuels Black Hole Growth?
2012-04-03 04:46:20

"Black holes are very efficient eating machines“¦ They can double their mass in less than a billion years. That may seem long by human standards, but over the history of the Galaxy it's pretty fast,” said Scott Kenyon of the Harvard-Smithsonian Center for Astrophysics (CfA). New research presented by a joint team from the CfA and the University of Utah showed these super-massive star destroyers can balloon in size by absorbing one-half of a binary star system. ...

In a world first, the sounds of Mars and Venus are revealed as part of a planetarium show in Hampshire this Easter. Despite many years of space exploration, we have no evidence of the sound of other planets. While most planetary probes have focused on imaging with cameras and radar and a couple have carried microphones, none of them successfully listened to the sound of another world. Now, a team from the University of Southampton, led by Professor Tim Leighton, has the answer. Using...

Study Discovers How Massive Black Holes Grow So Rapidly
2012-03-25 04:42:56

Black holes that grow to masses billions of times greater than that of our sun most likely reached those sizes by consuming objects from multiple locations at the same time, researchers from the UK and Australia claim in a new study set for publication in the journal Monthly Notices of the Royal Astronomical Society. In a Friday press release, officials with the University of Leicester, who conducted the study along with colleagues from Australia's Monash University, compared the process...

Runaway Planets At 30 Million Miles Per Hour Possible
2012-03-22 13:27:20

Harvard-Smithsonian Center for Astrophysics researchers have determined that some planets are flying around in space at 30 million miles per hour. These hypervelocity planets are produced in the same way as the hypervelocity star that was found seven years ago traveling around the Milky Way Galaxy at 1.5 million miles per hour. "These warp-speed planets would be some of the fastest objects in our Galaxy," astrophysicist Avi Loeb of the Harvard-Smithsonian Center for Astrophysics said in...

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...
