The U.S. National Aeronautics
and Space Administration (NASA) have put together two million infrared
images of Milky Way from the orbiting Spitzer Space Telescope to create a
360-degree portrait of it
In 2003, NASA sent the Spitzer Space Telescope in the space to take pictures of the Galaxy enclosing our planet. After about a decade, it has already taken millions of pictures that will show us how our galaxy looks like.
The Galactic Legacy Infrared Midplane
Survey Extraordinaire (GLIMPSE) team from the University of
Wisconsin-Madison, who compiled the images, described the Milky Way as a
flat spiral disk. When we look to the core of it, which can only be
done using of infrared light, we will see a crowded and dusty region
filled with starts. Our planet on the other hand, is situated in the
outer one-third of the galaxy.
Imaging specialist Robert Hurt of the
NASA Spitzer Space Science Center in Pasadena said in a press release,
that they can show it in a monitor or a billboard as big as the Rose
Bowl Stadium to view it.” But since that would be unachievable, they
have created a digital viewer that anyone can look at.
The mosaic, which is 20 gigapixels big,
uses Microsoft’s WorldWide Telescope visualization platform. It shows
more than 50 percent of all the stars in the galaxy because it focuses
on a band were the plane of the Milky Way is situated. It shows an
exceptional view of the plane of the Milky Way.
“For the first time, we can actually
measure the large-scale structure of the galaxy using stars rather than
gas,” said Edward Churchwell, a professor of astronomy at the University
of Wisconsin-Madison, to Science 2.0. “We've established beyond the
shadow of a doubt that our galaxy has a large bar structure that extends
halfway out to the sun's orbit. We know more about where the Milky
Way's spiral arms are.”
The new image of the Milky Way, which is named GLIMPSE360, is presented Friday in the TED conference in Vancouver.Source
