## Transcript

[0:46] SPEAKER_00: Welcome to Science Is Not Boring by Kidopoly.com.
[0:50] SPEAKER_00: I'm Mira! And I'm Finn! Hey Finn, did you know that every single day about 44,000 kilograms of space rock and dust falls onto our planet?
[1:02] SPEAKER_00: Wait, 44,000 kilograms?
[1:05] SPEAKER_00: That is like the weight of ten huge elephants falling out of the sky.
[1:09] SPEAKER_00: Are we going to get squished?
[1:12] SPEAKER_00: No, don't worry.
[1:13] SPEAKER_00: You don't need a hard hat.
[1:15] SPEAKER_00: Almost all of that space stuff never reaches the ground.
[1:19] SPEAKER_00: But where does it go?
[1:20] SPEAKER_00: Does it just vanish?
[1:21] SPEAKER_00: It burns up.
[1:23] SPEAKER_00: And when it does, it creates one of the most beautiful sights in the night sky.
[1:28] SPEAKER_00: Today we are talking about shooting stars.
[1:31] SPEAKER_00: Oh, I love shooting stars.
[1:33] SPEAKER_00: I always try to make a wish when I see a bright streak in the sky.
[1:37] SPEAKER_00: Well, get ready for a mind-blowing fact.
[1:39] SPEAKER_00: A shooting star is not a star at all.
[1:42] SPEAKER_00: The stars we see at night are giant balls of burning gas, like our sun, up to a few thousand light years away.
[1:49] SPEAKER_00: So if it's not a star, what is zooming across the dark sky?
[1:53] SPEAKER_00: It's usually a tiny piece of space rock or dust, called a meteoroid, often no bigger than a single grain of sand.
[2:01] SPEAKER_00: A grain of sand?
[2:02] SPEAKER_00: How can something that tiny make such a huge bright flash?
[2:06] SPEAKER_00: Because it is moving unbelievably fast.
[2:10] SPEAKER_00: These little space crumbs hit our atmosphere at average speeds of about 30,000 miles per hour.
[2:19] SPEAKER_00: That's way faster than a rocket ship.
[2:21] SPEAKER_00: Exactly.
[2:22] SPEAKER_00: And because it's zooming through the air so fast, it squishes the air in front of it.
[2:28] SPEAKER_00: This creates intense friction and pressure, heating the tiny rock up to 3,000 degrees Fahrenheit.
[2:35] SPEAKER_00: 3,000 degrees?
[2:37] SPEAKER_00: That would melt almost anything.
[2:39] SPEAKER_00: So it basically turns into a tiny fireball.
[2:42] SPEAKER_00: Yep, it vaporizes, glowing white hot about 60 miles above our heads.
[2:48] SPEAKER_00: Once it hits the atmosphere and glows, scientists call it a meteor.
[2:53] SPEAKER_00: So where do all these space crumbs come from in the first place?
[2:57] SPEAKER_00: Is space just super messy?
[2:59] SPEAKER_00: Kind of.
[3:00] SPEAKER_00: Many of them come from comets.
[3:02] SPEAKER_00: Comets are like giant dirty snowballs orbiting the sun, and as they travel, they leave behind a trail of dusty debris.
[3:11] SPEAKER_00: Oh, like dropping breadcrumbs in the forest.
[3:13] SPEAKER_00: Exactly.
[3:14] SPEAKER_00: And when Earth's orbit ploughs right through that trail of crumbs, we get a meteor shower.
[3:20] SPEAKER_00: For example, there's a wild one in late June called the June Buotids.
[3:25] SPEAKER_00: Bootids?
[3:26] SPEAKER_00: That's a funny name.
[3:28] SPEAKER_00: Are they fast?
[3:29] SPEAKER_00: Actually, they are known for being very slow-moving meteors, hitting the air at around 18 kilometres per second, and they are famous for surprise shows.
[3:39] SPEAKER_00: Surprise shows?
[3:41] SPEAKER_00: What happens?
[3:42] SPEAKER_00: Usually you might see only one or two an hour.
[3:45] SPEAKER_00: But in 1998, Earth hit a really dense patch of comet dust from Comet Pons Winnicki, and suddenly people saw up to 100 meteors an hour.
[3:56] SPEAKER_00: Okay, so a grain of sand burns up.
[3:59] SPEAKER_00: But what if a bigger rock falls?
[4:01] SPEAKER_00: Like, what if it's the size of a baseball?
[4:04] SPEAKER_00: If a space rock survives the fiery trip through the atmosphere and actually hits the ground, it gets a new name.
[4:11] SPEAKER_00: It's called a meteorite.
[4:14] SPEAKER_00: And that brings us to an incredible story from October 9th, 1992.
[4:19] SPEAKER_00: Ooh, I love a good story.
[4:21] SPEAKER_00: Where did it happen?
[4:22] SPEAKER_00: In a town called Peakskill, New York.
[4:25] SPEAKER_00: An 18-year-old girl named Michelle Knapp had just bought her first car.
[4:31] SPEAKER_00: A red 1980 Chevy Malibu for$400.
[4:35] SPEAKER_00: Haha, a 1980 Chevy Malibu?
[4:38] SPEAKER_00: That sounds like a cool retro ride.
[4:41] SPEAKER_00: She thought so, but that evening she was hanging out at home when suddenly she heard a deafening crash outside.
[4:50] SPEAKER_00: She said it sounded like three cars smashing into each other.
[4:54] SPEAKER_00: Oh no! Did someone crash into her new car?
[4:57] SPEAKER_00: She ran outside to the driveway, and there was a huge hole punched straight through the trunk of her car.
[5:03] SPEAKER_00: And underneath the car, buried in the gravel, was a weird football-shaped rock.
[5:09] SPEAKER_00: A space rock hit her car.
[5:11] SPEAKER_00: How big was it?
[5:12] SPEAKER_00: It weighed 26 pounds.
[5:15] SPEAKER_00: Scientists calculated that this rock had been flying through space at about 25,000 miles per hour before the atmosphere slowed it down.
[5:24] SPEAKER_00: Wait, it slowed down?
[5:26] SPEAKER_00: How fast was it going when it actually hit the car?
[5:29] SPEAKER_00: It slowed down to about 164 miles per hour when it slammed into the Chevy Malibu.
[5:35] SPEAKER_00: Oh, and Finn, you'll love this part.
[5:38] SPEAKER_00: When Michelle got close to the rock, it was still warm to the touch, and it smelled awful.
[5:44] SPEAKER_00: Ew! What did a space rock smell like?
[5:48] SPEAKER_00: It smelled strongly of rotten eggs.
[5:50] SPEAKER_00: That's because of the sulphur inside it.
[5:53] SPEAKER_00: Scientists found out the rock was 4.4 billion years old.
[5:58] SPEAKER_00: 4.4 billion years floating in space?
[6:01] SPEAKER_00: Just to end up smashing into a car in New York?
[6:04] SPEAKER_00: That is the unluckiest car ever.
[6:06] SPEAKER_00: Actually, it was incredibly lucky.
[6:09] SPEAKER_00: Because it became the famous Peak Skill meteorite car.
[6:13] SPEAKER_00: Collectors bought the broken car from her for$10,000.
[6:17] SPEAKER_00: Okay, a£26-pound rock is heavy.
[6:19] SPEAKER_00: But what is the absolute biggest meteorite ever found?
[6:23] SPEAKER_00: Was it the size of a house?
[6:25] SPEAKER_00: Get ready for this.
[6:27] SPEAKER_00: The biggest intact meteorite on Earth is called the Hoba meteorite.
[6:32] SPEAKER_00: It was discovered in the African country of Namibia in the year 1920.
[6:38] SPEAKER_00: 1920?
[6:39] SPEAKER_00: How did they find it?
[6:40] SPEAKER_00: Did someone see a massive fireball?
[6:43] SPEAKER_00: Nope, it fell a long, long time ago.
[6:46] SPEAKER_00: A farmer named Jacobus Hermanus Britz was just ploughing his field with his ox.
[6:52] SPEAKER_00: Suddenly, his plough screeched to a halt with a loud metallic scraping sound.
[6:57] SPEAKER_00: A metallic sound?
[6:59] SPEAKER_00: Under the dirt?
[7:00] SPEAKER_00: Yes.
[7:01] SPEAKER_00: He started digging and digging and realised he hadn't hit a buried tractor.
[7:06] SPEAKER_00: He had hit a solid slab of iron from outer space that was about nine feet across.
[7:11] SPEAKER_00: Nine feet across?
[7:13] SPEAKER_00: Wait, how much did it weigh?
[7:15] SPEAKER_00: It weighed an astonishing 60 tonnes.
[7:18] SPEAKER_00: That's as heavy as about ten adult elephants packed into one giant block of metal.
[7:24] SPEAKER_00: 60 tons falling from space?
[7:26] SPEAKER_00: It must have made a crater the size of a whole city.
[7:29] SPEAKER_00: You'd think so, right?
[7:31] SPEAKER_00: But here is the wildest part of the Hober meteorite story.
[7:35] SPEAKER_00: It left almost no crater at all.
[7:37] SPEAKER_00: What?
[7:38] SPEAKER_00: How is that even possible?
[7:39] SPEAKER_00: A 60-ton rock hitting the dirt should make a massive hole.
[7:43] SPEAKER_00: Scientists believe it fell less than 80,000 years ago, and because it was unusually flat on both sides, it hit the Earth's atmosphere at a very shallow angle.
[7:53] SPEAKER_00: Like skipping a flat stone across the water at a pond.
[7:56] SPEAKER_00: Exactly.
[7:57] SPEAKER_00: The atmosphere acted like water, slowing it way down to terminal velocity before it just thumped into the ground in one giant piece.
[8:06] SPEAKER_00: You can still go to Namibia today and sit on it.
[8:09] SPEAKER_00: Sitting on a 60-ton piece of space iron.
[8:14] SPEAKER_00: That is so cool.
[8:15] SPEAKER_00: I want to find a meteorite in my backyard.
[8:18] SPEAKER_00: It's pretty rare, but scientists study them because meteorites are the ultimate time capsules.
[8:24] SPEAKER_00: They tell us exactly what the solar system was made of 4.56 billion years ago, just slightly before Earth formed.
[8:33] SPEAKER_00: So when we look up at a meteor shower, we are watching ancient history burning up in the sky.
[8:38] SPEAKER_00: Exactly! And speaking of burning up, did you know shooting stars can be different colours?
[8:44] SPEAKER_00: Really?
[8:45] SPEAKER_00: Like a rainbow?
[8:46] SPEAKER_00: What makes them change colours?
[8:48] SPEAKER_00: It depends on what kind of metal is inside the rock.
[8:51] SPEAKER_00: If the meteor has a lot of a metal called magnesium, it glows bright green.
[8:57] SPEAKER_00: If it has sodium, it glows yellow or orange.
[9:00] SPEAKER_00: A glowing green fireball?
[9:02] SPEAKER_00: That sounds like something from an alien movie.
[9:04] SPEAKER_00: No wonder people make wishes on them.
[9:07] SPEAKER_00: Actually, the tradition of wishing on a shooting star is super old.
[9:11] SPEAKER_00: An ancient Greek astronomer named Ptolemy believed that the gods occasionally got curious and opened a crack in the sky to look down at Earth.
[9:20] SPEAKER_00: And when they opened the sky, the stars slipped out.
[9:24] SPEAKER_00: That's what he thought.
[9:25] SPEAKER_00: Since the gods were already looking down right at that moment, it was the perfect time to quickly ask for a wish.
[9:32] SPEAKER_00: Haha, that's a lot better than wishing on a rock that smells like rotten eggs.
[9:36] SPEAKER_00: Alright Finn, time for the quiz.
[9:39] SPEAKER_00: Are you ready?
[9:40] SPEAKER_00: Okay, I'm ready.
[9:42] SPEAKER_00: Hit me with your best space facts.
[9:44] SPEAKER_00: First question.
[9:46] SPEAKER_00: How hot can a meteor get when it zooms into our sky?
[9:52] SPEAKER_00: Next one, what is a shooting star that actually hits the ground called?
[10:01] SPEAKER_00: Question three.
[10:02] SPEAKER_00: What kind of car got smashed by the Peakskill space rock?
[10:09] SPEAKER_00: Here's number four.
[10:11] SPEAKER_00: What was the heavy 60-ton meteorite found in Namibia called?
[10:20] SPEAKER_00: Last question.
[10:21] SPEAKER_00: What colour does a shooting star glow if it is full of magnesium?
[10:28] SPEAKER_00: Great job! Let's see how you did.
[10:31] SPEAKER_00: The first answer is, it heats up to an amazing 3,000 degrees Fahrenheit.
[10:37] SPEAKER_00: For question 2, a rock that survives the trip to the ground is called a meteorite.
[10:43] SPEAKER_00: Number 3, the answer is it was a red, 1980 Chevy Malibu.
[10:50] SPEAKER_00: Question 4.
[10:51] SPEAKER_00: That massive chunk of iron is known as the Hober meteorite.
[10:55] SPEAKER_00: And the final answer is, magnesium makes a meteor glow bright green.
[11:01] SPEAKER_00: I still can't believe a grain of sand can light up the whole sky.
[11:04] SPEAKER_00: Or that a huge iron rock skipped across the atmosphere like a stone on a pond.
[11:10] SPEAKER_00: Science is full of wonderful surprises.
[11:12] SPEAKER_00: Next time you look up at the night sky, just think about all the ancient history flying around up there.
