00:00.780 --> 00:16.690
web


00:16.690 --> 00:19.370
follow the arc to Artur this and hit a
spike

00:19.370 --> 00:24.020
to spike hey there sorry gazers and in
re guess astronomer for the Cincinnati

00:24.020 --> 00:24.850
Observatory


00:24.850 --> 00:28.390
and I'm James Aubrey director the key
cassava pop planetarium in Gainesville

00:28.390 --> 00:28.939
Florida


00:28.939 --> 00:33.020
we're gonna do a little star hopping
this week and discover new stars

00:33.020 --> 00:36.430
and constellations are jumping off point
will be the Big Dipper

00:36.430 --> 00:40.579
the Big Dipper the most recognizable
star pattern visible most to the year

00:40.579 --> 00:42.320
will be your guide to the heavens


00:42.320 --> 00:46.500
first it all points to the North Star
then shows the way to the bright orange

00:46.500 --> 00:47.050
star


00:47.050 --> 00:50.680
terrace then lead us to the brilliant
blue star spike a

00:50.680 --> 00:53.720
ever will even be a planted along the
way lets show

00:53.720 --> 00:59.330
okay we have our April skies set up to
10 p.m. facing north East

00:59.330 --> 01:02.490
where we see the Big Dipper high above
the North Star

01:02.490 --> 01:06.439
its couples for water it be pouring
right internal dipper

01:06.439 --> 01:10.390
and overflowing onto the ground ball up
if we shoot an arrow through the two

01:10.390 --> 01:12.590
stars on the end of the big dippers Cup


01:12.590 --> 01:16.210
and continue that line in a run smack
dab into the North Star

01:16.210 --> 01:20.408
now let's use the big dippers handle to
find two more wonderful stars

01:20.408 --> 01:24.780
and a planet simply draw an imaginary
line through the handle the Big Dipper

01:24.780 --> 01:28.470
an extended out along the curve or arc
and your

01:28.470 --> 01:32.870
arc your way to the bright star Park
Terrace so in other words repeat after

01:32.870 --> 01:33.380
me


01:33.380 --> 01:37.360
follow the arc to work towards follow
the actor terrace

01:37.360 --> 01:41.860
pay it's pretty catchy thanks just a
little something I came up with are

01:41.860 --> 01:45.370
tourists is the brightest star in the
constellation below tease the herds

01:45.370 --> 01:50.520
his outline looks more like a narrow
kite or an ice cream cone on its side

01:50.520 --> 01:55.370
without doing that scooping ice cream is
falling on your after you

01:55.370 --> 01:59.270
art Park Terrace keep going straighten
out the arc a bit

01:59.270 --> 02:03.170
and to the right you run into the bright
blue star called spike a

02:03.170 --> 02:07.350
spike is the brightest star in the
constellation Virgo the maiden

02:07.350 --> 02:11.009
she's standing operate and covers most
to the eastern sky

02:11.009 --> 02:14.730
their catchy saying to find spike a of
course

02:14.730 --> 02:18.629
first we follow the arc torturous her
then hit a spike

02:18.629 --> 02:21.720
to spike Wow at a lot less catchy


02:21.720 --> 02:25.459
yeah I now but maybe it's so bad you
remember anyway

02:25.459 --> 02:28.690
let's compare arc tourists and Spike it
to

02:28.690 --> 02:32.420
our star the Sun arc turns is relatively
close to us

02:32.420 --> 02:35.450
only 37% light years away Spyker


02:35.450 --> 02:39.520
is about seven times farther around 261
like yours

02:39.520 --> 02:43.530
the Sun on the other hand is only eight
light minutes away

02:43.530 --> 02:46.690
now what size these three stars up


02:46.690 --> 02:50.620
the Sun is about eight hundred
sixty-five thousand miles in diameter

02:50.620 --> 02:53.930
that's large enough for 109 hurts to
struct

02:53.930 --> 02:57.640
and and across its with but that's
nothing compared to spike

02:57.640 --> 03:01.290
which is over seven times wider than our
Sun and our terrace

03:01.290 --> 03:04.880
which is over 25 times wider this


03:04.880 --> 03:08.010
artwork Torres and Spike to spike a
trick works

03:08.010 --> 03:11.400
every spring but this year we have
something extra

03:11.400 --> 03:15.110
you're probably wondering about that
extra point light above spike

03:15.110 --> 03:18.459
it's really bright and a little red so


03:18.459 --> 03:21.709
let's follow the arc torturous spike to
Spyker

03:21.709 --> 03:24.720
and then motor up to mars %ah


03:24.720 --> 03:28.970
the red planet you probably noticed mars
in the evening sky

03:28.970 --> 03:33.629
rising in the east after sunset not only
does it have a distinctive color

03:33.629 --> 03:38.180
but it doesn't went well as much as the
stars do earlier this month marshals

03:38.180 --> 03:39.870
that its closest point to the year


03:39.870 --> 03:44.920
but now the earth stone leaving mars
behind you know mars is almost 60

03:44.920 --> 03:46.250
million miles away


03:46.250 --> 03:50.310
you'll still be able see it in the
evening skies for the restive 2014

03:50.310 --> 03:54.660
since mars a planet it wanders around
the background stars

03:54.660 --> 03:58.250
it just happens to be in the right place
this year to crash are

03:58.250 --> 04:01.739
arc to work tourists and Spike to spike
a party n

04:01.739 --> 04:04.890
adds a little extra spice your evening
star gazing

04:04.890 --> 04:09.120
cell this spring get outside and let the
Big Dipper be your guide

04:09.120 --> 04:12.730
the two stars on the end of the spoon
will take you to the North Star

04:12.730 --> 04:16.279
and the curve stars in the handle will
let you art tartar us

04:16.279 --> 04:19.589
hit a spike to Spyker and motor up to
mars

04:19.589 --> 04:23.169
and as you spin around the galaxy this
week remember to

04:23.169 --> 04:53.719
heat look enough


04:53.719 --> 04:57.830
