Beauty grace mystery this magnificent
spiral galaxy has it all captured by the
nasa/esa Hubble Space Telescope the
galaxy NGC three three four four
presents itself to us face on providing
astronomers with the chance to study its
intricate and elegant structure and with
Hubble's ability to observe the galaxies
over a wide range of different
wavelengths features are revealed to us
that would otherwise remain invisible
[Music]
spiral galaxies are some of the most
spectacular astronomical objects we can
see and each one faces us at a different
angle making strikingly different shapes
in the sky some can be seen a John
giving astronomers an excellent idea of
the galaxies vertical structure others
are seen at an angle providing hints of
the size and structure of their spiral
arms strikingly many are seen face on
fully showcasing their arms and bright
core in all their beauty approximately
20 million light-years away the galaxy
NGC 3 3 4 4 phases directly towards
Earth giving us breathtaking views of
its swirling arms with all the wonderful
instruments on board Hubble we can see
more than just the visible light this
galaxy emits Hubble's instruments have
observed this galaxy in a variety of
wavelengths delivering a more complete
picture of the structure composition and
behavior of NGC 3 3 4 4 then the human
eye could ever see
the whirling arms of NGC 334 for our the
birthplace of new stars these stars are
extremely hot and young so they shine a
brilliant blue they also emit
ultraviolet light which Hubble captures
and allows us to observe clouds of dust
and gas are also distributed throughout
the spiral arms these are seen best in
the red part of the spectrum using
Hubble's narrow band filters to isolate
H alpha and n3 doubly ionized nitrogen
the clouds colored red in this image
provide the reservoir of material which
will one day form new stars at the
center of the galaxy lies the Galactic
bulge shining in yellow orange light
like the Bulge in the Milky Way it is
composed primarily of older cooler stars
which emit red light
Papa lets us admire the beauty of NGC
three three four four invisible light
but it also lets us learn about this
galaxy's secret internal composition all
with light that is around us but that
our eyes cannot see
[Music]
you
now that you've caught up with Hubble
make sure to get the latest from the
ground too
the esocast highlights the best of the
european southern observatory and its
powerful telescopes that observe from
high in the chilean andes at the
southern hemisphere's best known sites
