DEAN:
HEY THERE STAR GAZERS.

00:24.357 --> 00:27.093 align:left position:72.5%,start line:83% size:17.5%
I'M DEAN REGAS, ASTRONOMER FOR THE CINCINNATI
OBSERVATORY.

00:27.193 --> 00:29.562 align:left position:42.5%,start line:83% size:47.5%
JAMES:
AND I'M JAMES ALBURY, DIRECTOR OF THE KIKA

00:29.662 --> 00:31.664 align:left position:22.5%,start line:83% size:67.5%
SILVA PLA PLANETARIUM
IN GAINESVILLE,

00:31.765 --> 00:32.832 align:left position:40%,start line:89% size:50%
FLORIDA.

00:32.932 --> 00:34.601 align:left position:87.5%,start line:83% size:2.5%
WE'VE GOT GOOD NEWS AND SOME EVEN
BETTER NEWS.

00:34.701 --> 00:39.005 align:left position:70%,start line:83% size:20%
THE GOOD NEWS IS THAT THE PERSEID METEOR SHOWER,
TRADITIONALLY THE BEST METEOR SHOWER

00:39.105 --> 00:41.841 align:left position:35%,start line:83% size:55%
OF THE YEAR,
WILL PEAK WEDNESDAY NIGHT AUG 12TH THROUGH

00:41.941 --> 00:43.376 align:left position:30%,start line:83% size:60%
THURSDAY MORNING
THE 13TH.

00:43.476 --> 00:45.845 align:left position:42.5%,start line:83% size:47.5%
DEAN:
BUT THE EVEN BETTER NEWS IS THAT THE MOON

00:45.945 --> 00:48.248 align:left position:87.5%,start line:83% size:2.5%
WILL BE OUT OF THE PICTURE DURING
THE PEAK.

00:48.348 --> 00:52.052 align:left position:70%,start line:83% size:20%
MEANING WE'LL HAVE EXTRA-DARK SKIES FOR WATCHING
THE PERSEIDS THIS YEAR.

00:52.152 --> 00:54.054 align:left position:42.5%,start line:83% size:47.5%
JAMES:
GET PREPARED BECAUSE WE'RE GOING TO SHARE

00:54.154 --> 00:55.922 align:left position:25%,start line:83% size:65%
OUR TIPS AND TRICKS
TO OBSERVING A

00:56.022 --> 00:57.323 align:left position:32.5%,start line:89% size:57.5%
METEOR SHOWER.

00:57.424 --> 01:00.326 align:left position:42.5%,start line:83% size:47.5%
DEAN:
THE BEST TIME TO LOOK FOR THE PERSEID METEOR

01:00.427 --> 01:04.731 align:left position:72.5%,start line:83% size:17.5%
SHOWER IS LATE AT NIGHT ON THE 12TH OF AUGUST,
AND INTO THE EARLY MORNING OF THE 13TH.

01:04.831 --> 01:06.800 align:left position:42.5%,start line:83% size:47.5%
JAMES:
HERE'S RULE # 1 :

01:06.900 --> 01:07.801 align:left position:30%,start line:89% size:60%
HOPE IT'S CLEAR.

01:07.901 --> 01:09.702 align:left position:30%,start line:83% size:60%
BECAUSE IF IT'S
CLOUDY OR RAINING

01:09.803 --> 01:11.304 align:left position:87.5%,start line:89% size:2.5%
YOU WON'T SEE ANY METEORS AT ALL.

01:11.404 --> 01:12.405 align:left position:42.5%,start line:83% size:47.5%
DEAN:
RULE # 2 :

01:12.505 --> 01:15.208 align:left position:70%,start line:89% size:20%
"GET AS FAR AWAY FROM CITY LIGHTS AS POSSIBLE".

01:15.308 --> 01:18.545 align:left position:77.5%,start line:83% size:12.5%
BECAUSE EVEN THOUGH YOU MAY SEE A HANDFUL
OF THE BRIGHTEST METEORS FROM

01:18.645 --> 01:22.782 align:left position:30%,start line:83% size:60%
CITY LOCATIONS,
THE CITY LIGHTS FLOOD THE SKY WITH SO MUCH

01:22.882 --> 01:27.720 align:left position:77.5%,start line:83% size:12.5%
SKY-GLOW THAT NOWADAYS MANY OF THE METEORS
IN A METEOR SHOWER ARE HIDDEN FROM VIEW.

01:27.821 --> 01:29.255 align:left position:42.5%,start line:83% size:47.5%
JAMES:
RULE # 3

01:29.355 --> 01:33.193 align:left position:82.5%,start line:83% size:7.5%
"OBSERVE WHILE LYING ON THE GROUND ON
A BLANKET OR IN A LAWNCHAIR".

01:33.293 --> 01:35.595 align:left position:30%,start line:83% size:60%
IN OTHER WORDS,
KEEP LOOKING UP!

01:35.695 --> 01:37.764 align:left position:32.5%,start line:83% size:57.5%
NO TELESCOPES,
NO BINOCULARS NEEDED!

01:37.864 --> 01:39.632 align:left position:42.5%,start line:83% size:47.5%
DEAN:
RULE # 4:

01:39.732 --> 01:44.337 align:left position:72.5%,start line:83% size:17.5%
"STAY OUTSIDE FOR AT LEAST A COUPLE OF HOURS,
PREFERABLY AFTER MIDNIGHT AND HAVE PLENTY

01:44.437 --> 01:45.338 align:left position:32.5%,start line:89% size:57.5%
OF PATIENCE."

01:45.438 --> 01:46.773 align:left position:42.5%,start line:83% size:47.5%
JAMES:
IF YOU FOLLOW THESE RULES,

01:46.873 --> 01:50.110 align:left position:77.5%,start line:83% size:12.5%
YOU CAN EXPECT TO SEE SEVERAL METEORS PER
HOUR AND MAYBE

01:50.210 --> 01:51.878 align:left position:37.5%,start line:89% size:52.5%
MANY MORE.

01:51.978 --> 01:56.149 align:left position:75%,start line:83% size:15%
SIMPLY LIE BACK AND CONSTANTLY SCAN THE SKY
AND USUALLY WHEN YOU LEAST EXPECT IT,

01:56.249 --> 01:59.119 align:left position:72.5%,start line:89% size:17.5%
A METEOR OR EVEN TWO WILL ZIP ACROSS THE SKY.

01:59.219 --> 02:01.821 align:left position:42.5%,start line:83% size:47.5%
DEAN:
NOW ALTHOUGH SOME ASTRONOMY WEBSITES WILL

02:01.921 --> 02:05.859 align:left position:85%,start line:83% size:5%
TELL YOU THAT YOU MAY SEE 60 METEORS
PER HOUR,

02:05.959 --> 02:11.564 align:left position:75%,start line:83% size:15%
WHICH WOULD BOIL DOWN TO ABOUT ONE A MINUTE,
METEORS REALLY DON'T OPERATE ON A TIME SCHEDULE.

02:11.664 --> 02:16.269 align:left position:77.5%,start line:83% size:12.5%
YOU MAY SEE TEN OF THEM IN TWO MINUTES AND
THEN HAVE TO WAIT FOR 20 MINUTES TO SEE ANOTHER

02:16.369 --> 02:17.770 align:left position:45%,start line:89% size:45%
ONE.

02:17.871 --> 02:20.240 align:left position:72.5%,start line:83% size:17.5%
BUT THAT'S THE FUN OF IT, BECAUSE EACH METEOR
IS A TOTAL SURPRISE.

02:20.340 --> 02:23.610 align:left position:42.5%,start line:83% size:47.5%
JAMES:
O.K., WE'VE GOT OUR SKIES SET UP FOR THE USUAL

02:23.710 --> 02:26.246 align:left position:37.5%,start line:83% size:52.5%
PEAK TIME
TO VIEW: AUGUST 13TH

02:26.346 --> 02:27.881 align:left position:30%,start line:89% size:60%
AFTER MIDNIGHT.

02:27.981 --> 02:32.552 align:left position:75%,start line:83% size:15%
ABOUT HALF WAY UP FROM THE HORIZON YOU WILL
SEE THE "W" SHAPE OF CASSIOPEIA.

02:32.652 --> 02:36.523 align:left position:77.5%,start line:83% size:12.5%
LOOK A LITTLE BELOW CASSIOPEIA AND THAT'S
WHERE THE METEORS WILL APPEAR TO ORIGINATE:

02:36.623 --> 02:37.891 align:left position:17.5%,start line:89% size:72.5%
THE CONSTELLATION PERSEUS.

02:37.991 --> 02:41.828 align:left position:42.5%,start line:83% size:47.5%
DEAN:
I KNOW THAT IS REALLY EARLY, BUT THE METEOR

02:41.928 --> 02:44.864 align:left position:77.5%,start line:83% size:12.5%
SHOWER WILL BE AT IT'S BEST BEFORE DAWN ON
THE 13TH.

02:44.964 --> 02:47.567 align:left position:42.5%,start line:83% size:47.5%
JAMES:
WONDER WHY THEY'RE CALLED THE PERSEIDS?

02:47.667 --> 02:52.438 align:left position:65%,start line:83% size:25%
WELL METEOR SHOWERS ARE NAMED FOR THE CONSTELLATION
FROM WHERE THE METEORS APPEAR TO ORIGINATE.

02:52.539 --> 02:55.241 align:left position:25%,start line:83% size:65%
BUT WHAT EXACTLY IS
A METEOR?

02:55.341 --> 02:58.845 align:left position:77.5%,start line:89% size:12.5%
LET'S TAKE YOU OUT INTO SPACE AND EXPLAIN.

02:58.945 --> 03:00.880 align:left position:42.5%,start line:83% size:47.5%
DEAN:
METEORS ARE THE FLASHES OF LIGHT WE

03:00.980 --> 03:05.585 align:left position:77.5%,start line:83% size:12.5%
SEE WHEN TINY SPECKS OF SPACE DEBRIS SLAM
INTO OUR EARTH'S ATMOSPHERE AND

03:05.685 --> 03:06.686 align:left position:37.5%,start line:89% size:52.5%
LIGHT UP.

03:06.786 --> 03:09.322 align:left position:40%,start line:83% size:50%
YOU SEE,
EVERY TIME A COMET VISITS OUR SUN IT

03:09.422 --> 03:11.291 align:left position:22.5%,start line:89% size:67.5%
SHEDS TONS OF DEBRIS.

03:11.391 --> 03:15.061 align:left position:77.5%,start line:83% size:12.5%
AND EVENTUALLY THIS STUFF GETS SPREAD OUT
ALONG THE COMET'S PATH.

03:15.161 --> 03:18.031 align:left position:42.5%,start line:83% size:47.5%
JAMES:
IF OUR EARTH PLOWS INTO THIS PATH,

03:18.131 --> 03:22.468 align:left position:75%,start line:83% size:15%
THESE TINY PIECES OF COMET LITTER WILL SLAM
INTO OUR EARTH'S ATMOSPHERE TRAVELING MANY

03:22.569 --> 03:24.337 align:left position:27.5%,start line:89% size:62.5%
MILES PER SECOND.

03:24.437 --> 03:28.474 align:left position:77.5%,start line:83% size:12.5%
THE PARTICLES THEMSELVES ARE FAR TOO SMALL
TO BE SEEN BUT THE FRICTION OF THESE PARTICLES

03:28.575 --> 03:30.810 align:left position:77.5%,start line:83% size:12.5%
HITTING THE AIR CAUSES THE AIR SURROUNDING
THEM

03:30.910 --> 03:32.345 align:left position:32.5%,start line:83% size:57.5%
TO HEAT UP AND
YOU SEE STREAKS

03:32.445 --> 03:33.546 align:left position:37.5%,start line:89% size:52.5%
OF LIGHT.

03:33.646 --> 03:35.682 align:left position:42.5%,start line:83% size:47.5%
DEAN:
AND WE CALL THESE STREAKS OF LIGHT METEORS

03:35.782 --> 03:38.651 align:left position:32.5%,start line:83% size:57.5%
OR INCORRECTLY
"FALLING STARS".

03:38.751 --> 03:44.057 align:left position:75%,start line:83% size:15%
THE METEORS WE SEE DURING THE PERSEID METEOR
SHOWER EACH AUGUST ARE DEBRIS FROM A COMET

03:44.157 --> 03:45.291 align:left position:42.5%,start line:83% size:47.5%
NAMED
SWIFT-TUTTLE.

03:45.391 --> 03:48.294 align:left position:42.5%,start line:83% size:47.5%
JAMES:
AND OUR EARTH PLOWS THROUGH ITS DEBRIS FIELD

03:48.394 --> 03:50.630 align:left position:87.5%,start line:89% size:2.5%
ABOUT THE SAME TIME EVERY AUGUST.

03:50.730 --> 03:54.801 align:left position:72.5%,start line:83% size:17.5%
THE PERSEID METOR SHOWER IS ONE OF THE OLDEST
RECORDED METEOR SHOWERS IN HISTORY AND HAS

03:54.901 --> 03:58.238 align:left position:75%,start line:89% size:15%
BEEN SEEN EVERY AUGUST FOR OVER 2000 YEARS!

03:58.338 --> 04:01.608 align:left position:42.5%,start line:83% size:47.5%
JAMES:
NOW LET ME REMIND YOU OF THE SINGLE MOST IMPORTANT

04:01.708 --> 04:03.743 align:left position:25%,start line:83% size:65%
RULE FOR OBSERVING A
METEOR SHOWER,

04:03.843 --> 04:07.947 align:left position:77.5%,start line:83% size:12.5%
WHICH IS YOU MUST CONSTANTLY SCAN THE SKY
AND HAVE PATIENCE.

04:08.047 --> 04:11.017 align:left position:75%,start line:83% size:15%
YOU MAY SEE NO METEORS FOR 20 MINUTES OR SO
AND THEN ALL

04:11.117 --> 04:13.686 align:left position:75%,start line:89% size:15%
OF A SUDDEN 2 OR 3 MAY FLASH BY ALL AT ONCE.

04:13.786 --> 04:15.555 align:left position:42.5%,start line:83% size:47.5%
DEAN:
BUT EACH TIME YOU SEE

04:15.655 --> 04:20.526 align:left position:70%,start line:83% size:20%
A PERSEID STREAK ACROSS THE SKY REMIND YOURSELF
THAT WHAT YOU'RE ACTUALLY SEEING IS A TINY

04:20.627 --> 04:22.562 align:left position:10%,start line:89% size:80%
COMET PIECE IGNITING YOUR NIGHT.

04:22.662 --> 04:26.662 align:left position:37.5%,start line:83% size:52.5%
BOTH: KEEP
LOOKING UP!
