Computing Paths to Asteroids Helps Find Future Exploration Opportunities
Greenbelt MD (SPX) Jul 18, 2014
As left over building blocks of the solar system's formation, asteroids are of significant interest to scientists. Resources, especially water, embedded within asteroids could be of use to astronauts traveling through deep space. Likewise, asteroids could continue to be destinations for robotic and human missions as NASA pioneers deeper into the solar system, to Mars and beyond. NASA is developing the capabilities needed for astronauts to reach Mars in the 2030s. To test these new technologi ... read more

Asteroid Vesta to reshape theories of planet formation EPFL researchers have a better understanding of the asteroid Vesta and its internal structure, thanks to numerical simulations and data from the space mission Dawn. Their findings, published in Natu ... more		Probe is headed for duck-shaped comet, images show New images reveal that the deep-space comet on which mankind plans to land a probe later this year, has an "extraordinarily irregular", duck-like shape, the European Space Agency (ESA) said Thursday. ... more		Twin comets discovered by ESA space probe Rosetta The European Space Agency's Rosetta probe has been gearing up to attempt a comet landing. Recently, the craft discovered something surprising about its intended target, Comet Churyumov-Gerasimenko. ... more
				Diving for pearls with the Hubble Space Telescope Stars forming like a string of blue pearls along two elliptical galaxies could be the result of a galactic merger, according to an international team of astronomers. The structure could reveal rare ... more		Small, faint but plentiful galaxies illuminated the early universe Light from tiny galaxies over 13 billion years ago played a larger role than previously thought in creating the conditions in the universe as we know it today, a new study has found. Ultraviolet (UV ... more

Tempur-Pedic Mattress Comparison & Memory Foam Mattress Review

Sun-like Stars Reveal Their Ages Defining what makes a star "Sun-like" is as difficult as defining what makes a planet "Earth-like." A solar twin should have a temperature, mass, and spectral type similar to our Sun. We also would ... more		Friction from Tides Could Help Distant Earths Survive, and Thrive As anybody who has started a campfire by rubbing sticks knows, friction generates heat. Now, computer modeling by NASA scientists shows that friction could be the key to survival for some distant Ea ... more		Sierra Space clears design milestone for missile tracking satellites in SDA Tranche 2 State Department sanctions North Koreans for role in arms sales Seoul official hints at US-North Korea meeting this year		NASA says it's close to finding alien life, Earth's twin At a panel discussion on the search for alien life, held this week at NASA's headquarters in Washington, the agency's top scientists said they're getting close. ... more
				Sky-gazers can expect one 'Supermoon' per month for the next three months Weather permitting, watchers of the night sky will be set aglow by a Supermoon this evening. A Supermoon is the same, regular moon, only it appears up to three-times bigger than normal. ... more		Out of An Hours-long Explosion, A Stand-In For The First Stars Astronomers analyzing a long-lasting blast of high-energy light observed in 2013 report finding features strikingly similar to those expected from an explosion from the universe's earliest stars. If ... more

Landsat Looks to the Moon Every full moon, Landsat 8 turns its back on Earth. As the satellite's orbit takes it to the nighttime side of the planet, Landsat 8 pivots to point at the moon. It scans the distant lunar surface m ... more		Hubble Spots Spiral Bridge of Young Stars Linking Two Ancient Galaxies NASA's Hubble Space Telescope has photographed an unusual structure 100,000 light years long, which resembles a corkscrew-shaped string of pearls and winds around the cores of two colliding galaxies ... more		The first animals on Earth may have been sea sponges, study suggests Swiss glaciers shrank by a quarter in past decade: study South Asia monsoon: climate change's dangerous impact on lifeline rains		Merging galaxies and droplets of starbirth The Universe is filled with objects springing to life, evolving and dying explosive deaths. This new image from the NASA/ESA Hubble Space Telescope captures a snapshot of some of this cosmic movemen ... more
Ferromagnetism at 230 K found in diluted magnetic semiconductor Diluted magnetic semiconductors (DMS) have received much attention due to their potential application in spintronics, or the storage and transfer of information by using an electron's spin state, it ... more		Astronomers Bring The Third Dimension To A Doomed Star's Outburst In the middle of the 19th century, the massive binary system Eta Carinae underwent an eruption that ejected at least 10 times the sun's mass and made it the second-brightest star in the sky. Now, a ... more		Newfound Frozen World Orbits in Binary Star System A newly discovered planet in a binary star system located 3,000 light-years from Earth is expanding astronomers' notions of where Earth-like-and even potentially habitable-planets can form, and how ... more		Cosmic grains of dust formed in supernova explosion There are billions of stars and planets in the universe. A star is glowing sphere of gas, while planets like Earth are made up of solids. The planets are formed in dust clouds that swirled around a ... more

	Supermassive black hole blows molecular gas out of galaxy New research by academics at the University of Sheffield has solved a long-standing mystery surrounding the evolution of galaxies, deepening our understanding of the future of the Milky Way. T ... more		VLT clears up dusty mystery The origin of cosmic dust in galaxies is still a mystery [1]. Astronomers know that supernovae may be the primary source of dust, especially in the early Universe, but it is still unclear how and wh ... more
