 | The space-borne telescope, COROT (Convection, Rotation and planetary Transits), has just completed its first year in orbit. The observatory has brought in surprises after over 300 days of scientific observations. ...> Full Article |
 | Inch by power-conserving inch, drivers on Earth have moved the Mars rover Spirit to a spot where it has its best chance at surviving a third Martian winter -- and where it will celebrate its fourth anniversary (in Earth years) since bouncing down on Mars for a projected 90-day mission in January 2004. ...> Full Article |

 | New Mexico Tech's Magdalena Ridge Observatory (MRO) is already making its mark in the annals of MROastronomy research after being recently tasked by NASA to make detailed observations of an asteroid that is now given a 1 in 75 chance of hitting Mars on January 30, 2008. ...> Full Article |
 | Astronomers have at last found definitive evidence that the universe's first dust – the celestial stuff that seeded future generations of stars and planets – was forged in the explosions of massive stars. ...> Full Article |
 | Researchers have dated the earliest step in the formation of the solar system -- when microscopic interstellar dust coalesced into mountain-sized chunks of rock -- to 4,568 million years ago, within a range of about 2,080,000 years. ...> Full Article |
 | Using observations from ESO's VLT, astronomers were able for the first time to reconstruct the site of a flare on a solar-like star located 150 light years away. The study of this young star, nicknamed 'Speedy Mic' because of its fast rotation, will help scientists better understand the youth of our Sun. ...> Full Article |
 | A team of astronomers has discovered a cosmic explosion that seems to have come from the middle of nowhere—thousands of light-years from the nearest galaxy-sized collection of stars, gas, and dust. ...> Full Article |
 | A furious rate of star formation discovered in a distant galaxy shows that galaxies in the early universe developed either much faster or in a different way from what astronomers have thought. ...> Full Article |
 | Jupiter's moon Europa is just as far away as ever, but new research is bringing scientists closer to being able to explore its tantalizing ice-covered ocean and determine its potential for harboring life. ...> Full Article |
 | MIT will lead a $375 million mission to map the moon's interior and reconstruct its thermal history, NASA announced this week. ...> Full Article |

 | Somewhere deep below Saturn's cloud tops, the planet rotates at a constant speed. Determining this interior period of rotation has proven extremely complicated. Now, with new Cassini results, a team of European scientists have taken an important step forward. ...> Full Article |
 | Research by a team of astronomers, including a Michigan State University professor and his students, has found that two halos of stars - not just one - rotate around our Milky Way galaxy. ...> Full Article |
 | New observations by NASA's Cassini spacecraft indicate the rings of Saturn, once thought to have formed during the age of the dinosaurs, instead may have been created roughly 4.5 billion years ago when the solar system was still under construction. ...> Full Article |
The first stars to form in the early universe may have been "dark stars" fueled by an altogether different engine than the stars visible in the night sky now, according to a team of physicists that includes professor Katherine Freese of the University of Michigan.

 | Scientists have discovered that our sun's 'atmosphere' is asymmetric, thanks to two champion spacecraft. ...> Full Article |
 | A team of astronomers have used the NASA/ESA Hubble Space Telescope to detect, for the first time, strong evidence of hazes in the atmosphere of a planet orbiting a distant star. The discovery comes after extensive observations made recently with Hubble's Advanced Camera for Surveys (ACS). ...> Full Article |
 | Five satellites launched last February to probe magnetic storms around the Earth will move into prime observing position next month, but they already have produced important new information on the interactions between the solar wind and the Earth's magnetic field. ...> Full Article |
 | It has been 35 years since humans last walked on the moon, but there has been much recent discussion about returning, either for exploration or to stage a mission to Mars. However, there are concerns about potential radiation danger for astronauts during long missions on the lunar surface. ...> Full Article |
Measures to protect astronauts from health risks caused by space radiation will be important during extended missions to the moon or Mars, say researchers in a paper currently online in Experimental Neurology.

 | Scrutiny by NASA's newest Mars orbiter is helping scientists learn the stories of some of the weirdest landscapes on Mars, as well as more familiar-looking parts of the Red Planet. ...> Full Article |
 | Enceladus, the tiny satellite of Saturn, is colder than ice, but data gathered by the Cassini-Huygens Mission to Saturn and Titan has detected a hot spot that could mean there is life in the old moon after all. In fact, for researchers of the outer planets, Enceladus is so intellectually hot, it's smokin'. ...> Full Article |
 | NASA's Voyager 2 spacecraft has followed its twin Voyager 1 into the solar system's final frontier, a vast region at the edge of our solar system where the solar wind runs up against the thin gas between the stars. ...> Full Article |
 | Scientists have gathered more evidence that suggests flowing water on Mars -- by comparing images of the red planet to an otherworldly landscape on Earth. ...> Full Article |
 | Using the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) instruments on board NASA's Solar Terrestrial Relations Observatory (STEREO) spacecraft, a consortium of scientists has seen, for the first time, large waves of solar material sweeping past Earth. ...> Full Article |
 | The Voyager 2 spacecraft's Plasma Science instrument, developed at MIT in the 1970s, has turned up surprising revelations about the boundary zone that marks the edge of the sun's influence in space. ...> Full Article |
 | A collaboration of over 50 astronomers, The IPHAS consortium, led from the UK, with partners in Europe, USA, Australia, has released today (10th December 2007) the first comprehensive optical digital survey of our own Milky Way. Conducted by looking at light emitted by hydrogen ions, using the Isaac Newton Telescope on La Palma, the survey contains stunning red images of nebulae and stars. The data is described in a paper submitted to the Monthly Notices of the Royal Astronomical Society. ...> Full Article |
 | The Sun is minimally active right now, but this quiet state of affairs won't last for long. Over the next few years, the number of solar flares and eruptions known as coronal mass ejections will increase until reaching solar maximum in 2011 or 2012. Such eruptions can impact Earth, disrupting satellites, communications, and even power grids. Some predict the next solar cycle will be the most intense in 50 years. As a result, scientists are striving to understand the mechanism behind solar eruptions in hopes of eventually being able to predict them in a space "weather forecast." ...> Full Article |
