A state of the art satellite is being sent into space to monitor the blind zone between the Earth and the sun to warn of incoming asteroids.

Astronomers have previously not been able to spot asteroids in the 'blind zone' due to radiation from the sun blocking information.

But now The European Space Agency intends to launch the Gaia Space Telescope with its key task being to monitor the area between the Earth and the sun and warn of any impending collisions.

One recent asteroid which could have been spotted as it travelled through the 'blind zone' months before it collided with the Earth, was that of the Russian asteroid of February this year which caused a spectacular fireball before smashing into Chelyabinsk, 900 miles east of Russia.

Gerry Gilmore, professor of experimental philosophy at Cambridge University's Institute of Astronomy told the Sunday Times: "Gaia will measure all the asteroids including those between us and the sun which are the really nasty ones because we can't see them."

During its five-year-mission the £800million Gaia will also map the stars with unprecedented precision - giving astronomers the first accurate 3D map of our galaxy and measure distance between the stars.

A spokseman for the ESA said: "During its anticipated lifetime of five years, Gaia will observe each of its 1billion sources about 70 times, resulting in a record of the brightness and position of each source over time.

"Together with the unprecedented accuracy of the astrometric measurements, this will lead to the discovery of planets around other stars, asteroids in our Solar System, icy bodies in the outer Solar System, brown dwarfs, and far-distant supernovae and quasars.

"The list of Gaia's potential discoveries makes the mission unique in scope and scientific return."

The satellite completed final preparations in Europe last year and will take off from a launch site in French Guiana on November 20.
