Liverpool Telescope Successor In The Works
2013-07-02 04:32:37

Lee Rannals for redOrbit.com - Your Universe Online The scientific community is designing a successor to the 2-meter Liverpool Telescope (LT) located on La Palma. The Astrophysics Research Institute of Liverpool John Moores University (LJMU), which owns and operates LT, is developing plans for the new telescope. So far, they've said Liverpool Telescope 2 (LT2) will be a 4-meter class facility. "We've been having productive talks with the Instituto de Astrofisica de Canarias and hope...

ESA's 3D Star-Mapping Satellite Gaia Moving To Launch Facility
2013-06-27 16:09:26

[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...

A Look Into The Gaia Mission
2013-06-24 11:07:16

ESA [ Watch The Video Gaia Sunshade Deployment ] Gaia, ESA’s billion-star surveyor, will be launched into space towards the end of this year. In the meantime, ESA Space Science has launched a new ‘minisite’ focused on the Gaia mission. At www.esa.int/gaia you will find the latest news from the mission, as well as background articles explaining the mission objectives, the spacecraft, its heritage and more. You’ll also find links to in-depth reports and journal entries...

Gaia Mission To Detect Ultra-cool Dwarfs In The Milky Way
2013-02-14 05:47:05

April Flowers for redOrbit.com - Your Universe Online There are small subsets of stars among the hundred billion in the Milky Way called ultra-cool dwarfs, which have a temperature below 2500 Kelvin. Both ultra-cool dwarfs and brown dwarfs exist at these lower temperatures. The lower temperatures indicate that these are some of the most ancient objects in our Galaxy, leading scientists to examine them for information on primitive chemical composition. The Gaia mission, which will be...

Tests Completed For Gaia Launcher Separation and Payload Module Acceptance Vibration
2012-10-30 09:54:41

ESA Testing of the separation of the Gaia Service Module from its Launch Vehicle Adapter has been completed, as have the acceptance vibration tests on the Payload Module. Two more important test campaigns have been completed, taking Gaia closer to launch readiness. The operation of the mechanism that will separate the spacecraft's Service Module (SVM) from the upper stage of its launcher has been verified and acceptance level vibration testing of the Payload Module (PLM) has been...

Instruments Installed, Gaia Ready For Testing
2012-09-17 07:54:53

The payload module of ESA´s billion-star surveyor Gaia is integrated and ready for the next stage of rigorous testing it must undergo before launch next year. Once in space, Gaia will make precise measurements of the positions and motions of a billion stars. The information will be used to create a 3D map of stars in our home Galaxy, the Milky Way, revealing information about its composition, formation and evolution. This latest image shows the payload module in the Astrium...

Heat Dialed Down On ESA’s Billion-star Surveyor
2012-09-10 08:52:12

ESA´s Gaia mission to survey a billion stars has passed a grueling test to prove it can withstand the extreme temperatures it will experience in space when it is launched next year. After arrival at its working position some 1.5 million km from Earth, Gaia will operate at a temperature of —110°C, shielded from the heat of the Sun by a giant shade attached to the spacecraft to keep its instruments in permanent shadow. The focus of the most recent test was Gaia´s...

Gaia's Antenna Checks Out Under ESA Tests
2012-07-03 04:26:06

Lee Rannals for redOrbit.com - Your Universe Online ESA announced on Monday that its Gaia billion-star surveyor's main antenna's test is running on schedule. After launching next year, the antenna will send Gaia's science data to Earth from its location about 930,000 miles away from Earth. Gaia is expected to download 200 terabytes of data over its five year mission, which is the equivalent of nearly 45,000 standard DVDs. The ESA spacecraft will be making precise measurements of...

Gaia Spreads Its Wings
2011-12-08 04:30:17

[ Watch the Video ] ESA´s Gaia star-mapper has passed a critical test ahead of its launch in 2013: the spacecraft´s sunshield has been deployed for the first time. Gaia's sunshield is an essential component of the mission. It keeps Gaia in shadow, maintaining the scientific instruments at a constant temperature of around —110°C. The sunshield is about 10 m across, which is too large for the launch vehicle fairing, so it has been built with a dozen folding panels...

Draco (dragon or serpent) Constellation -- Location: Northern Hemisphere; Coordinates: Right Ascension: 17h; Declination: +65; Source: Creation and dragon myths from Greek, Roman, eastern Mediterranean, Middle East, Indian and Norse cultures Two circumstances lie behind the multitude of myths associated with Draco. First, due to the precession of the Earth, Draco's star Thuban was the pole star approximately 4000 years ago. It would have seemed to ancient sky watchers that the Earth...
