ESA's Gaia Mission Is Beginning To See Things More Clearly
2014-02-06 13:37:15

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency’s (ESA) billion-star surveyor mission is slowly beginning to see more clearly. ESA’s Gaia launched on December 19, 2013, and since then it has been preparing for its mission to gather loads of data on stars that surround us. Gaia took a test image of a dense cluster of stars in the Large Magellanic Cloud as part of a “fine tuning” test to get the spacecraft into focus. The new image is allowing ESA...

[ Watch The Video: Journey to a Billion Suns Trailer ] ESA A new planetarium show, Journey to a billion Suns, premieres today in Hamburg, Germany, to tell the fascinating story of mapping the Milky Way, from ancient times to ESA’s recently launched Gaia mission. The 45-minute, 360 degree full-dome planetarium spectacular was produced by Stargarten in cooperation with ESA and planetariums across Europe. Gaia was launched on 19 December and will soon start its five-year...

[WATCH VIDEO: Gaia Scanning The Sky] Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency's (ESA) Gaia spacecraft is ready for departure to its launch site in French Guiana. Gaia will be embarking on a five-year mission to map the stars and create a highly accurate 3D map of our Milky Way galaxy. ESA said the spacecraft has completed final preparations in Europe and is ready to depart to its final pit stop on Earth before launch. The billion-star surveyor...

Methuselah Star Birth Certificate
2013-03-08 08:38:30

April Flowers for redOrbit.com - Your Universe Online The ink is drying on a brand new birth certificate for a star that's been around for a very long time. New calculations using NASA'S Hubble Space Telescope have enabled a group of astronomers to take an important step closer to reconciling the age of this star, and the age of the Universe. "We have found that this is the oldest known star with a well-determined age," said Howard Bond of Pennsylvania State University in University...

ESA's mission to measure the precise positions of a billion stars reached an important milestone on September 3 with the delivery of its first primary mirror. The second primary mirror is near completion and scheduled to arrive at the Toulouse test and integration center of prime contractor EADS Astrium during October. Gaia will carry two identical telescopes, each fitted with four mirrors (M1 to 4). A further two mirrors (M5 and 6) will send the light from these dual instruments...

Gaia, ESA's next-generation star mapper, will be carried into space by a Soyuz-STB/Fregat launch vehicle from Europe's Spaceport in French Guiana. David Southwood, ESA's Director of Science and Robotic Exploration, signed the contract for the launch with Jean-Yves LeGall, Chairman and CEO of Arianespace, at ESA Headquarters in Paris yesterday. The mission builds upon the heritage of precision stellar mapping exemplified by ESA's now- completed Hipparcos mission. Gaia will map 1000 million...

Austin, TX -- Having the sharpest pictures always is a big advantage, and a sophisticated radio-astronomy technique using continent-wide and even intercontinental arrays of telescopes is yielding extremely valuable scientific results in a wide range of specialties. That's the message delivered to the American Astronomical Society's meeting in Austin, Texas, by Mark Reid of the Harvard-Smithsonian Center for Astrophysics, a leading researcher in the field of ultra-precise astronomical position...

It has been ten years since the release of the Hipparcos and Tycho catalogues, the first astrometric catalogues produced from observations in space. The Hipparcos catalogue has since been re-processed and fine-tuned, providing the best map of our galaxy to date. ESA's Hipparcos (High Precision Parallax Collecting Satellite), launched in 1989, was the first, and so far only, space-based astrometry mission. Designed to determine the position and distance of more than 100 000 stars, its accuracy...
