The
image below shows a breathtaking view of
the core of our galaxy, the Milky Way, as seen by the VISTA telescope from the
European Space Agency. With the naked eye, you’d probably
see the center of the Milky Way—with countless stars and cosmic dust
clouds—occupying a small patch of a few inches.
However,
thanks to the VISTA telescope we got one of the most detail portraits of the
Milky Way EVER produced which has allowed astronomers to catalog a staggering
84 million stars. After seeing this image, ask yourself. are we
alone in the Milky Way? The above image is just a small, reduced—thumbnail version
of the original image which has a mind-boggling resolution of 108,500×81,500—or if you prefer 9 gigapixels, occupying
24.6 gigabytes. If for some reason you want to download the 24.6-gigabyte image you can
do so by clicking here. Check out the ENTIRE
9-gigapixel image—and zoom in on those stars—by clicking

displayed at full resolution and is best appreciated using the zoom tool.
In
order to obtain this image, ESO’s VISTA telescope—which stands for Visible and
Infrared Survey Telescope for Astronomy—snapped thousands of images of the sky
after which astronomers compiled them into one 9 gigapixel mosaic. The Vista
telescope is one of the LARGEST visible and near infrared telescopes on the
planet, and it just showed us how cool it really is which this mind-bending
image.
The
image you are seeing is crystal clear because the VISTA telescope boasts a stunning infrared camera which
enables it to peer through the dust clouds that obscure the view of other
telescopes. In order to understand how powerful the VISTA telescope really is, here below is a comparison between an
image of the Milky Way—the same image—as seen from an infrared telescope and a
visible telescope.
Pretty
amazing right? Just imagine what else is out there? The Milky Way galaxy is really
unique, it’s beautiful and this image makes you love our cosmic home even more, right?
But this image wasn’t taken just for aesthetic purposes. In fact, this massive image has
allowed scientists and astronomers to identify numerous cosmic
objects in space that are worth researching further.
This
image allowed astronomers to identify 84 million stars in the Milky Way. Our cosmic home—the Milky Way—is part
of a supermassive structure interconnected by over 800 galaxies located at
around 1000 million light years away. Our galaxy is part of an intergalactic highway that
stretches some 500 million light years across and contains around
100,000,000,000,000,000 Suns, dubbed by scientists as Laniakea.
Oh and, just a fun fact here, did you know that astronomers maintain that there are around 500 billion galaxies in the known universe, which means there are around 50,000,000,000,000,000,000,000 (5×1022) habitable planets. Astronomers argue that just inside our Milky Way Galaxy, there are some 400 BILLION STARS.
