UMaine Engineering Team To Test Inflatable Habitats For NASA Moon Mission Orono ME (SPX) Apr 04, 2008 
NASA faces many challenges in its quest to establish a colony on the moon by 2020, and providing suitable shelter for the next generation of space explorers is at the top of the list. An inflatable lunar habitat, one of several concepts now on the drawing boards, must be lightweight and flexible enough to minimize packaging size and transportation costs. Once deployed, the expanded structure ... read more |

Black Hole Found In Omega Centauri
Paris, France (ESA) Apr 04, 2008Omega Centauri has been known as an unusual globular cluster for a long time. A new result obtained by the NASA/ESA Hubble Space Telescope and the Gemini Observatory reveals that the explanation behind omega Centauri's peculiarities may be a black hole hidden in its centre. One implication of the discovery is that it is very likely that omega Centauri is not a globular cluster at all, but ... more Northrop Grumman Awarded Five Study Contracts For NextGen Astronomy Missions 
Redondo Beach CA (SPX) Apr 04, 2008Northrop Grumman is a partner on five contracts awarded by NASA to investigate concepts for next-generation space telescopes. The concepts include a powerful successor to the Hubble Space Telescope, three planet finding missions, and a futuristic x-ray space telescope. The study results will be submitted for consideration to the scientific community during the upcoming National Academy of ... more The Source Of The Solar Wind 
Belfast, Ireland (SPX) Apr 04, 2008An international team of scientists have found the source of the stream of particles that make up the solar wind. In a presentation on Wednesday 2 April at the RAS National Astronomy Meeting in Belfast, Professor Louise Harra of the UCL-Mullard Space Science Laboratory explained how astronomers have used a UK-led instrument on the orbiting Hinode space observatory to finally track down the ... more The Sun's Magnetic Fountains 
London, UK (SPX) Apr 02, 2008Astronomers have known for decades that the Sun has a very dynamic atmosphere. Huge fountains of hot gas erupt in the atmosphere, or corona, every few minutes, travelling at tens of thousands of km per hour and reaching great heights. Now a team of scientists have used the Hinode spacecraft to find the origin and driver of these fountains - immense magnetic structures that thread through the ... more Workers Ready Course For NASA's 15th Annual Great Moonbuggy Race 
Huntsville AL (SPX) Apr 03, 2008Each year around this time, John Tripp walks across a lunar surface, pondering the challenges ahead for explorers brave enough to take on its cratered terrain. For now, his "moon" is a winding ribbon of cement footpaths looped around Huntsville's famed U.S. Space and Rocket Center, where Tripp is a construction foreman. By month's end, a half-mile of the paths will be transformed into a ha ... more |

Santa Barbara CA (SPX) Apr 02, 2008An international team of astronomers has found 10 new "extra solar" planets, planets that orbit stars other than our sun. The team used a system of robotic cameras that yield a great deal of information about these other worlds, some of which are quite exotic. The system is expected to revolutionize scientific understanding of how planets form. Two participating astronomers from the U.S. ... more Two New Star Systems Are First Of Their Kind Ever Found 
Columbus OH (SPX) Apr 02, 2008Astronomers have spied a faraway star system that is so unusual, it was one of a kind -- until its discovery helped them pinpoint a second one that was much closer to home. In a paper published in a recent issue of the Astrophysical Journal Letters, Ohio State University astronomers and their colleagues suggest that these star systems are the progenitors of a rare type of supernova. They ... more NASA Scientists Identify Smallest Known Black Hole 
Greenbelt MD (SPX) Apr 02, 2008Using a new technique, two NASA scientists have identified the lightest known black hole. With a mass only about 3.8 times greater than our Sun and a diameter of only 15 miles, the black hole lies very close to the minimum size predicted for black holes that originate from dying stars. "This black hole is really pushing the limits. For many years astronomers have wanted to know the smallest ... more A Vision For Exploration 
Moffett Field CA (SPX) Apr 01, 2008There are many fascinating places in our solar system to explore, but space missions are dangerous and expensive. Sending robots instead of people helps reduce these drawbacks. For this kind of exploration, Professor Bernard Foing looks to the Moon, Mars and beyond, hoping to discover tantalising secrets useful to astrobiologists. Foing is the senior research coordinator at the European ... more |

Huntsville AL (SPX) Mar 31, 2008Bright gray, crater-pocked mountains taller than Mount McKinley. Abyssal craters that could swallow several Grand Canyons whole. Recent radar maps of the Moon's southern pole revealed a dramatic, jagged landscape that astronauts could someday call home. But unfortunately, these radar images didn't provide any new information about something that would make living at the lunar pole much easier ... more A World Of Possibilities Gives Perspective On Life On Enceladus 
Houston TX (JSC) Mar 28, 2008Could microbial life exist inside Enceladus, where no sunlight reaches, photosynthesis is impossible and no oxygen is available? To answer that question, we need look no farther than our own planet to find examples of the types of exotic ecosystems that could make life possible on Saturn's geyser moon. The answer appears to be, yes, it could be possible. It is this tantalizing potential that ... more Ancient Meteorite Impact Crater Found In Britain 
Aberdeen, Scotland (SPX) Mar 28, 2008Evidence of the biggest meteorite ever to hit the British Isles has been found by scientists from the University of Aberdeen and the University of Oxford. The scientists believe that a large meteorite hit northwest Scotland about 1.2 billion years ago near the Scottish town of Ullapool. Previously it was thought that unusual rock formations in the area had been formed by volcanic activity. ... more Astronomers Coordinating International Observatories In White-Dwarf Watch 
Newark, DE (SPX) Mar 28, 2008Judi Provencal is star-struck, but not so much by the glitz and glam of Hollywood. You have to look heavenward through a telescope to see the object of her fascination--to pale stars called white dwarfs, their brilliance faded because all of their nuclear fuel has been burned up. A white dwarf is a star that is "dying," cooling down in the twilight of its life. It's what the sun will ... more
