flying along the Milky Way Heather
stargazers
I'm james oberg director the key cassava
plant planetarium in Gainesville Florida
I'm di Maria's astronomer for the
Cincinnati Observatory
this week will be your guide to the
galaxy yep
we're going to show you the Milky Way
something I hardly
ever get to see in Florida how many
times have you seen the Milky waiting
haha the call the Milky Way I see in
Cincinnati is a
filled with chocolate and new get for me
light pollution is a big problem
citylights aluminate signs parking lots
buildings and also the night sky
the more like that we shine up the less
like the stars
shine down even though it's invisible
from cities James and I can share as
sneaky tip to find the Milky Way in your
Sky
let's show you okay let's pretend it's
10 o'clock at night
and we're far from city lights may hand
it's dark out here
now and look at all the summer stars you
can see so many stars that you can't
even count them all
you can also see a band a faint light
stretching from the northeast
up overhead and down to the southwest
this
is the Milky Way when you look at the
Milky Way you're observing
billions and billions of stars most the
stars in our galaxy are stretched out in
a band
all around us with us in the middle
there are so many stars a our line of
sight that they appear as milky clouds
most ancient cultures were just as
fascinated with the Milky Way
as they were with any planet or
constellation you can definitely see why
out in the country it dominates the sky
some bright and famous constellations
can be found along this galactic River
such as Casio Pierre the Queen Cygnus
the Swan
and Scorpius the Scorpion Cassie appear
as one of the most recognizable
constellations
in the summer evenings she sits on her
throne
in the north eastern sky what you mean
those stars that look like the letter W
that's a queen
use your imagination Dean well that
picture certainly helps but
I guess some imagination challenged in
that case
picture this W shape stars as Cassie
apiece crowned sparkling with five
stellar joel's
okay now that I can see now
kickback and look high in the sky almost
straight overhead you'll see three very
bright stars marking the summer triangle
the summer triangle is not an official
constellation
it's really three constellations Lyra
the harp
Cygnus the Swan and a quality Eagle
let's focus on Cygnus since it's
probably the easiest to identify
because its cross like shape in fact
it's also called the northern cross
sicknesses brightest star is Dana which
marks the tale The Swan
sickness is located in an extremely rich
part in the Milky Way
so imagine it flying along the Great
river in the sky
near dead the Milky Way branches into
two channels
leaving a dark region in the middle this
is called the sickness rift
or the northern call sec now face South
here the Milky Way threads between two
xoxo constellations
Scorpius and secretary s Scorpius the
scorpion is
easy to spot with its bright red star
for heart and its curtail
and stinger stars the stars and said the
terrace resemble more about teapot been
a centaur wielding a bow and arrow
when you look between Scorpius and said
it areas you're peering into the center
of our galaxy
in that direction are billions and
billions of stars
and at the very center those is a
supermassive black hole
X-ray satellites have captured amazing
activity around this region called Sajan
teri is a
of course you can see the Milky Way
if you're a citibank and stargazer let's
show you the difference between a rural
sky
and a light polluted skies yaks
what a difference even though the Milky
Way's disappeared
we still have three constellations
clearly visible to guide us
Casio p in the Northeast Cygnus high
overhead
and Scorpius low in the south and that's
where the Milky Way
is even if you can't see it once you
identify Casio p.m.
Cygnus or scorpions scan these regions
on the sky with the not
just a little magnification well stars
will be revealed
so start counting those billions and
billions of stars tonight
as you keep looking up
