On Thursday (19/12/13), the European Space Agency ESA launched an advanced telescope designed to detect more than one billion stars and make the most detailed map of the Milky Way.
Gaia telescope successfully brought by a Soyuz-Fregat rocket from ESA's base in Kourou, French Guiana. Similarly, the agency reported via webcast.
"All went well," commented ESA issued. The satellite began on duty 42 minutes after launch.
With the equipment is very sensitive and stable, Gaia will be able to accurately observe objects in space.
Census astronomy
Satellites worth around 740 million euros, or nine trillion rupiah a space telescope's most advanced ever built by Europeans. These satellites were made for the purpose of 'census astronomy' more than one billion stars, or about one percent of all stars in the Milky Way.
With this telescope, position, color and light of a total of one billion stars can be tracked. Gaia has an image sensor that consists of 106 individual detectors. Together, with this camera will be able to produce nearly one billion pixel image. It is dozens of times more than that can be demonstrated professional SLR camera.
Observing other possibilities
The satellite is expected to help the search of planets outside the solar system. Astronomers assume 50,000 extrasolar planets can be monitored during the satellite work, ie five years.
Gaia will observe the asteroid belt between Mars and Jupiter, to help the search of asteroids that might someday threaten Earth. Approximately 250,000 asteroids and comets are not known from the solar system can also be observed.
Selain itu, Gaia juga berguna untuk membantu berjaga-jaga jika terjadi ledakan bintang alias supernova, yang sangat jarang bisa diamati secara real-time.
200,000 DVDs to store
According to German media, der Spiegel, for processing the data from Gaia, disbursed about 200 million euros. Six data center will handle a flood of data sent satellites. It is estimated to save the data that is needed around 200,000 DVDs.
"Gaia is the machine the greatest invention in the field of astronomy," says Alvaro Giménez Cañete, who is the Director of Science and Robotic Exploration ESA. He added that this would make Europe into a 'pioneer in precision astronomy.

More than 430 scientists who are members of the Consortium Data Processing and Analysis Consortium Gaia will work up to ten years to evaluate the information. The results of the first observation will probably be available within the next three to four years. While the final evaluation is expected to be seen in early 2022.
Nearly 20 years time it takes to prepare for the Gaia mission. Finally, the mission was again delayed due to the final seconds of telecommunications technology should have a replacement.
