Astronomy with the Świat Głuchych — World of the Deaf #1

Stars, galaxies, comets, black holes… in one word - space. What is? How it works? What do we know about him?

Imagine a big city with skyscrapers, traffic, lights on all sides and ubiquitous advertisements; but let’s forget about it. Imagine you’re out of town on a beautiful night. The sky is clear. The moon is not shining either. There is peace around you. It’s so dark you can’t blink because you can’t see your own hand. There is perfect darkness around you.

Will you count the stars?

And now you look up to the sky. What do you see? A huge number of stars. Stars – you are trying to count them. You have already counted 10 stars. You keep counting. You already have 20, 50. Will you be able to count them all? No. You start to get confused in counting because you don’t know which ones you’ve already counted and which you haven’t. What’s more, the longer you look at the sky, the more stars you see. Why? Your eyes adjust to the dark, you see more and more. It seems impossible to count all the stars. You stop counting and continue to stare in amazement at the beautiful sky full of stars. And maybe you are asking yourself: what’s further? What is the cosmos?

Have you ever seen such a sky? If so, you are really lucky. Unfortunately, it is getting harder and harder to see a sky full of stars. There are fewer and fewer places that are really dark, free from artificial light. And unfortunately, the number of such places will decrease. Thanks to the development of technology, we know more and more about the universe. The current knowledge of the cosmos is incomparably greater than that of astronomers 100 years ago.

Strange times for astronomy

We live in strange times – on the one hand, we know more and more about the universe. On the other – more and more people live in cities and NEVER see the stars, know nothing about them. When the earthquake in Los Angeles cut short of electricity in 1994, frightened people called emergency numbers saying there was “a huge silvery cloud” above the city. And what was this “cloud”? This was our galaxy, the Milky Way. You can see it on the photo. Was there any cause for concern? No. It’s just that these people saw the starry sky for the first time in their lives! More and more people know less and less about space. And the universe is beautiful and terrifying at the same time. We know more and more about the cosmos, we understand it more and more, but the more we know, the more mysterious it is and the more questions we have. The universe begins about 100 km above our heads and ends so far that man will NEVER be able to get there.

Cosmos in sign language

That is why we are happy to announce that Deaf’s Word Foundation starts a new series of videos that will explain many issues related to astronomy. You will learn, among others:

  • How does the star work?
  • What is a galaxy?
  • What is the difference between a planet and an planetoid?
  • How is a comet different from an asteroid?
  • What is a black hole?

And many others…

Do you like this idea? I encourage you to watch the next episodes. And now… I wish you many dark nights with cloudless skies — perfect conditions for observing the stars. Good luck. Bye!
