this is the esocast cutting-edge science
and life behind the scenes of Easter the
European Southern Observatory exploring
the universe's ultimate frontier with
our host dr. J aka dr. Joe Liske Orion
the Hunter is one of the most striking
constellations in the sky and is a
familiar sight to amateur and
professional astronomers are like the
Orion Nebula is faintly visible to the
naked eye as a didn't glow in the
hunters sword this swirling cloud of gas
and dust is 1,500 light-years from earth
and has fascinated astronomers since the
earliest days of the telescope appealing
to the eye as a small cluster of
blue-white star surrounded by mysterious
mist the negatives vast dusty regions
have long hidden from humanize an
enormous stellar nursery full of young
hot stars
the visible and infrared survey
telescope for astronomy or Vista has
taken a spectacular new image that
reveal some of the nebulas buried
secrets vista is the latest addition to
easels Paranal Observatory in Chile and
it's the largest survey telescope in the
world with a mirror measuring 4.1 meters
in diameter
it's dedicated to mapping the sky in the
infrared part of the spectrum by looking
in the infrared instead of visible light
mist is able to appear straight through
the obscuring gas and dust in your eye
nebula
that's because in the infrared at about
twice the wavelength of visible light
the dust in the nebular turns largely
transparent giving us a clear view of
the young stars that lie within
no other telescope has ever been able to
not only see through the dust to reveal
the hidden features buried within the
Orion Nebula but also to show its huge
extent an amazing detail in a single
image at the very heart of the nebula by
the four brilliant stars forming the
trapezium a group of very hot young
stars pumping out fierce ultraviolet
radiation that is clearing the
surrounding region and making the gas
glow observing in the infrared also
allows vista to reveal many other young
stars in the central region that cannot
be seen in visible light in this dusty
region of the nebula gas jets shot out
by young stars at around 700,000
kilometers an hour have collided with
the surrounding gas and dust exciting it
and sculpting strange red shapes
normally invisible these curious risks
provide important clues for astronomers
as they try to understand how stars are
born and what happens in their early
years as impressive as this image is it
is just the beginning of what Vista will
review with its unparalleled ability to
survey the sky both quickly and deeply

this is dr j signing off for the esocast
join me again next time for another
cosmic adventure
you're about the only person around it
doesn't have TV coverage of the food and
the man got the black up now you're
gonna be the start of the TV picture now
they'll yes we are going
baby pictures
one all
wait
