00:00:04.500 --> 00:00:05.760
It's my mom's birthday.

00:00:05.760 --> 00:00:08.300
I'm going to buy her a real star.

00:00:15.140 --> 00:00:21.480
Girl.  Cousin.  What you doing girl?
Oh nothing, just looking to buy a star. You know what

00:00:21.480 --> 00:00:27.900
I'm saying? A star! You can't buy a star. Yes you can online. Facts, facts.

00:00:27.900 --> 00:00:30.100
So what color are you planning on getting?

00:00:30.260 --> 00:00:33.620
What do you mean? Stars are only one color, white.

00:00:33.780 --> 00:00:39.200
Ha, ha, ha. Wrong. Stars are actually different colors.

00:00:39.880 --> 00:00:43.120
Did...did...did that TV just talk to us?

00:00:43.880 --> 00:00:46.480
Yes. Yes I did.
Now back to what I was saying.

00:00:46.480 --> 00:00:50.420
Stars may appear white, but if you look closely
there's a wide range of colors.

00:00:50.580 --> 00:00:58.800
Such as red, yellow, yellow-orange, white, yellow-white, blue and blue-white.

00:00:58.980 --> 00:01:01.060
Which color would you like to order?

00:01:01.060 --> 00:01:04.540
Pick blue! Pick blue! You know that's my favorite color.

00:01:04.540 --> 00:01:07.136
Yeah, okay, I guess I'll go with blue.

00:01:07.136 --> 00:01:08.229
Excellent choice.

00:01:08.229 --> 00:01:12.138
Although blue is the hottest star, it has the shortest lifespan.

00:01:12.138 --> 00:01:13.420
So what's the coldest?

00:01:13.420 --> 00:01:16.869
You would think that red would be the
hottest star but is actually the coldest and

00:01:16.869 --> 00:01:20.889
has the longest lifespan. The color of a star can determine its surface temperature

00:01:20.889 --> 00:01:24.279
as well as its mass and position in its
lifecycle.

00:01:24.279 --> 00:01:26.109
So, you mean to tell me that

00:01:26.109 --> 00:01:28.540
stars don't last forever?

00:01:28.540 --> 00:01:31.180
Correct.  Stars have a lifespan.

00:01:31.360 --> 00:01:36.000
For example,  the Sun is a yellow, medium-sized star that is halfway through predicted

00:01:36.009 --> 00:01:38.649
cycle of ten billion years.

00:01:38.649 --> 00:01:43.049
Wow, thanks TV lady. I would have never guessed.

00:01:43.280 --> 00:01:47.619
You want to go stargazing later?
