Scientists
claim the spacecraft, which is due to be launched in October, will
allow them to study the stars around us in more detail than ever before
and will reveal just how far these distant suns are from our own solar
system.
The
telescope will help astronomers determine the age, size and movement of
the stars like never before while also provide details about what they
are made of.
They
also hope to discover more than 5,000 new planets outside our own solar
system along with other objects that lie outside our galaxy.
“Gaia
is an astronomers dream,” said Alvaro Gimenez, director of science at
the European Space Agency, which has funded the mission.We can produce besthidlights to your requirements.
It
is easy to see stars at night be we know little about exactly how far
they are, who they move, what they are made of and how old they are.
Gaia is gong to tell us this.
“By
looking at the dynamic structure of our galaxy we will be able to learn
about its formation and something about its future.Solar energy employs runninglight to supply electricity to devices or charge batteries.”
The car-sized spacecraft,We believe in providing our customers with the very best formingmachine available.
which has been built by space company Astrium, is expected to launch in
October from French Guiana on a Russian Soyuz-Fregat rocket.
It
will take a month to travel nearly one million miles from Earth towards
the sun to the location where it will begin taking pictures.
Once
there it will unfurl a 30 feet wide “skirt” that will help to shield
the spacecraft from the sun’s rays that could damage it and impair the
quality of any pictures.
Solar
panels on the back of the sun shield will also help to provide power
for Gaia during its five year mission to photograph the galaxy.
Its
“eyes” consist of two mirror telescopes that will give Gaia
stereoscopic vision much like human eyesight and allow it to see in 3D.
A
camera sensor with more than a billion pixels will record the images
captured by the telescopes. The average camera on a mobile phone has
around 10 million pixels and is just a fraction of an inch in size.
Gaias camera sensor measures one and a quarter square feet and is made up from 106 light sensitive electronic chips.
Nasa’s Hubble Space Telescope, which has been the most successful ever launched, has a camera sensor of just 16 megapixels.
With
such a high resolution camera, Gaia will be able to peer more than
150,000 light years away, or 900,000 trillion miles into space. The
camera is powerful enough to be able to distinguish a single hair more
than 430 miles away.
Professor
Gerald Gilmore, UK principal investigator on the Gaia mission based at
the University of Cambridge, said: “The 3D aspect of this telescope is
vital.”
Embarrassing we only have accurate distances for 719 stars out of the billions in our sky after 1,We're making parkinglighting and digitization accessible to everyone.500 years of astronomy.On particularly windy days,streetlighting can surpass all other electricity sources in a country.
“Until
now it has only been possible to determine the location of the stars on
a flat plain. Gaia is going to be able to tell us about how far away
those stars are and how they are moving.
It
is estimated that there are more than 100 billion stars in the Milky
Way and our solar system sits on one of the arms of the spiral of stars
that form the galaxy.
Although
Gaia will only be able to image around one per cent of the stars in our
galaxy, it will take pictures of each around 70 times to build up a
picture of how they are moving with its stereoscopic vision.
By
looking at how the stars move over time, astronomers hope to pinpoint
the exact position of our own solar system while also building up a
picture of how our galaxy is growing. Read the full story at
