Satellite Gaia in search of other exoplanets? (C) ESA
Gaia is traveling. The European satellite at this time going through the Earth’s orbit. Inside it carries a heavy burden, whose importance throughout the study and that it will take to complete: the largest telescope in Europe. Great satisfaction of the ESA, but the enthusiasm must be curbed because up to the time when Gaia will not send the first communication with the Earth can not be said that everything went as it should. After the first communication satellite will reach the intended objective, or 1.5 million km from Earth where his adventure begins. Today we learn that the flight is almost half that between one and ten days Gaia can begin to map the Milky Way. And, some say, even to map other exoplanets, are still unknown.
“The launch of GAIA is a great success for the new ESA science. The aim is – the President of the Italian Space, Enrico Saggese – to make accurate and detailed stereoscopic observations of over a billion objects that are part of our Galaxy. The data from the telescopes of Gaia we expect, therefore, the results of particular importance in the field dell’astrometria, considerably better than the results obtained by the Hipparcos satellite. This mission, like those of the past, present and future, he sees a lot of Italian committed in the first person, with the help of ‘industry and research that takes place in our country. “Satellite_ESA_Gaia
“The mission GAIA – says Giovanni Bignami President of INAF – testifies to the excellence of our country in astrophysics. There are 8 INAF institutes and observatories that contribute to the success of the mission to which is added the ASI Data Center (ASDC), where researchers work INAF and ASI. Excellence that is recognized in international fora thanks to the contribution of many young researchers who deserve to be able to carry out their work without having to leave their own country. “
