Squeaks and I built this awesome observatory recently, and we love using it to look at
the night sky!
If you’ve ever looked up on a dark, clear night, you probably noticed that there are
a lot of things to see.
你能看见月亮 星星 甚至一些行星
You can see the Moon, the stars, and even some planets!
And if you’re really lucky, you might get to see a meteor: a streak of light that bursts
across the sky.
Since the light that meteors make looks kind of like the bright light that stars make,
a lot of people call meteors “shooting stars.”
But meteors aren’t stars at all!
在太空中 恒星是由气体组成出口的大球体 离地球很远
Stars are big balls of gas way out in space, far, far away from the Earth.
But meteors are caused by pieces of rock and metal that are pulled close to the Earth.
It all starts when a small piece of rock or metal breaks away
from something bigger in space.
Most of the time, these pieces are small — not much bigger than a grain of rice.
And some are only about the size of a piece of dust!
当这些小东西向地球跌落时 他们的速度非常快 以至于加热了周围的空气
When the pieces fall toward Earth, they’re going so fast that they heat up the air all
around them and burn up, making the air glow.
That’s the light we see in the sky — it’s a little piece of rock or metal burning up!
We call the falling piece a meteoroid, and the light it makes is the meteor.
当流星体彻底的燃烧 流星便消亡了 光亮也暗淡了
When the meteoroid is completely burned, the meteor is gone, and the light disappears.
If the piece is very small, the light might only last for less than a second.
If the piece is larger, though, the streak might race the whole way across the sky!
And if the piece is large enough, it can make it all the way through the layer of gases…
and hit the surface of the Earth.
If it does, then it gets a new name … a meteorite.
That’s a lot of words that sound almost the same.
但他们完全不同 流星是一条光迹 流星体是
But they’re all different: the meteor is the streak of light, the meteoroid is what
we call the bit of rock or metal as it falls, and the meteorite is what we call it when
it hits the ground.
Thousands of meteorites fall to the ground every year, but most of them are really small,
so we don’t notice them!
And there are even more meteoroids that burn up before they can get to the ground.
During certain times of the year, there are a lot more meteors than usual.
There can be 60 of them in an hour!
That’s called a meteor shower, because there are so many meteors falling through the sky
that it’s almost like we’re taking a shower in them!
I know, that is kind of funny!
Can you imagine taking a shower in falling rocks and dust?
I think I’d rather stick to water instead
Meteor showers happen because of something else in outer space, called a comet.
Comets are usually very far away from the Earth, all the way out at the edge of the
But sometimes one passes close by, right near the path where Earth moves around the sun!
当它经过时 彗星上的一些灰尘脱落了 可以在这
As it passes by, some dust from the comet breaks off, and the dust can stay in that
spot for a really long time.
Every year, when the Earth gets close to the spot where the dust is as it moves around
the sun, lots of the dust falls toward Earth, and each little piece of it creates a meteor.
That’s when we get a meteor shower!
There are a few different meteor showers all throughout the year.
场面壮观的流星雨在一月 四月 五月 七月 八月 十月 十一月和十二月
There are big ones in January, April, May, July, August, October, November, and December,
so there are lots of chances to see them!
In fact, Squeaks and I are about to get to see one of the biggest meteor showers of the
year, called the Perseids.
The best nights to see it are right around August 12.
You can ask a grownup to help you find out when you’ll next be able to see a meteor
然后你需要去找到一个漆黑的地方 抬头 接着欣赏流星雨
Then, all you need to do is to find a dark spot, look up … and enjoy the light show!
Have you ever seen a meteor?
How about a meteor shower?
