Latest The Universe Stories

Very First Stars Were Not Monstrous
2011-11-11 04:26:06

The very first stars in our universe were not the behemoths scientists had once thought, according to new simulations performed at NASA's Jet Propulsion Laboratory, Pasadena, Calif. Astronomers "grew" stars in their computers, mimicking the conditions of our primordial universe. The simulations took weeks. When the scientists' concoctions were finally done, they were shocked by the results -- the full-grown stars were much smaller than expected. Until now, it was widely believed that...

Researchers Say Nonterrestrial Artifacts Are Hard To Pin Down
2011-11-07 10:23:28

Two Pioneer probes left our solar system carrying plaques about humankind, and two Voyager probes will soon join them to gather information about places far out in our galaxy. We can and will send more autonomous probes into outer space, but why have we never found evidence of other civilizations doing the same? A pair of postdoctoral researchers at Penn State, approaching the problem mathematically, shows that we have not looked in enough places to ensure that no extraterrestrial artifacts...

Alien Hunters Should Look For 'City Lights'
2011-11-04 03:42:51

In the search for extraterrestrial intelligence, astronomers have hunted for radio signals and ultra-short laser pulses. In a new paper, Avi Loeb (Harvard-Smithsonian Center for Astrophysics) and Edwin Turner (Princeton University) suggest a new technique for finding aliens: look for their city lights. "Looking for alien cities would be a long shot, but wouldn't require extra resources. And if we succeed, it would change our perception of our place in the universe," said Loeb. As with...

Researchers Explain How The Milky Way Killed Off Its Satellites
2011-10-18 08:09:33

Two researchers from Observatoire Astronomique de Strasbourg have revealed for the first time the existence of a new signature of the birth of the first stars in our galaxy, the Milky Way. More than 12 billion years ago, the intense ultraviolet light from these stars dispersed the gas of our Galaxy's nearest companions, virtually putting a halt to their ability to form stars and consigning them to a dim future. Now Pierre Ocvirk and Dominique Aubert, members of the Light in the Dark Ages of...

PLAYA VISTA, Calif. and NEW YORK, Oct. 6, 2011 /PRNewswire/ -- The X PRIZE Foundation, the leading nonprofit organization solving the world's Grand Challenges by creating and managing large-scale, global incentivized competitions, today announced Shell as the exclusive presenting sponsor of the X PRIZE Exploration Prize Group, which aims to foster innovation through exploration to improve life on Earth. During the three-year, nine million dollar sponsorship, the X PRIZE Foundation will...

100 Year Starship Conference: Sex In Space
2011-10-05 07:47:02

Experts, gathering at DARPA´s 100 Year Starship conference in Florida which ended Oct. 2, discussed the possibility of making space flights to distant planets within the next 100 years. But the next closest star to Earth -- Alpha Centauri -- is more than 4 light years away and would take any conventional spaceship thousands of years to make the journey. NASA´s Voyager I probe, the furthest-traveled object man has ever put into space, has made it only one percent of the...

Most Ancient Supernovas Are Already Discovered
2011-10-05 06:30:26

Ten-billion-year-old exploding stars were a source of Earth's iron, TAU researchers say Supernovas – stars in the process of exploding – open a window onto the history of the elements of Earth's periodic table as well as the history of the universe. All of those heavier than oxygen were formed in nuclear reactions that occurred during these explosions. The most ancient explosions, far enough away that their light is reaching us only now, can be difficult to spot. A project...

Image 1 - ESA Selects Next Two Science Missions
2011-10-04 11:53:02

The powerful influence of the Sun and the nature of the mysterious 'dark energy' motivate ESA´s next two science missions. Solar Orbiter and Euclid were selected today by ESA's Science Programme Committee for implementation, with launches planned for 2017 and 2019. These two missions are medium-class missions and are the first in ESA's Cosmic Vision 2015-2025 Plan. Solar Orbiter will venture closer to the Sun than any previous mission. It is designed to make major breakthroughs in...

Image 1 - Citizen Scientists May Have Found New Planets
2011-09-22 04:05:00

   Since the online citizen science project Planet Hunters launched last December, 40,000 web users from around the world have been helping professional astronomers analyze the light from 150,000 stars in the hopes of discovering Earth-like planets orbiting around them. Users analyze real scientific data collected by NASA's Kepler mission, which has been searching for planets beyond our own solar system – called exoplanets – since its launch in March 2009. Now...

New Method Could Help Scientists Detect Dark Matter
2011-09-19 13:35:51

  Researchers from Princeton University and New York University have developed a method for detecting the collision of stars with a black hole that could help scientists uncover dark matter. Postdoctoral researchers Shravan Hanasoge of Princeton's Department of Geosciences and Michael Kesden of NYU's Center for Cosmology and Particle Physics simulated the result of primordial black hole passing through a star.  Scientists believe that primordial black holes posses the...

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...
