What if one day an ant would say, “I want to know what is going on in the world? I also want to know where everything comes from!” Do you think that an ant, with its size, could learn everything about the Earth? You would probably say, “What an ambitious ant!”
If I am like the ant or in a simple way, if I would like to know the entire thing going on in world or where everything comes from, what things I must know or learn?; what interesting things must I discover?; and how could I discover these things?
In some ways an astronomer is like a tiny ant trying to figure out what is going on in the universe. An astronomer studies the space beyond the Earth’s atmosphere. The space is a mighty big place. The Earth is just a dot compared to the seize of the Sun. The Sun on the other hand, is just a tiny speck in the arm of the Milky Way Galaxy. There are millions of other galaxies in space.
Astronomers are scientists in the field of science called astronomy. Astronomy is the scientific study of everything in the universe beyond the Earth’s atmosphere. Astronomy has different areas of study. There are astronomers that concentrate on the study on the stars and interplanetary dust; other astronomers study the galaxies; while others study the solar system. As most of the people get ready for bed at night, astronomers are just starting their work. Although the stars are still up in the sky during daytime, we cannot see them too clearly. It is because the sun’s light is much brighter than the light of the other stars. This is why most astronomers like to work at night.
The workplace of astronomers is called an observatory. Here, powerful telescopes are used to study stars and other heavenly bodies. The word “telescope” literally means seeing far. The telescope is probably the most important instrument of astronomers.
Observatories are usually built in high places with dry climate. These high places usually are above the densest, dustiest, and dampest part of our atmosphere thus, they provide clearer views of the heavens.
Our galaxy, the Milky Way, is composed of around 100,000 million stars. Some are dwarfs, which are much dimmer than our Sun while some are giants, which are far brighter than the Sun. If our own Sun is so much bigger than Earth that Earth appears as a small dot compared to it, can you just imagine how huge the space is which is occupied by 100,000 million stars? And what’s more, there are millions of other galaxies.
Astronomers have a lot of interesting things to study. There are millions of galaxies that contain millions of stars; some of the stars even have their own planets. Astronomers, just like an ambitious and curious ant, look for clues to answer the question: “How did the universe begin? Where did everything come from?”
Ahhh… I know all these longings would forever remain dreams in my imagination. They’ll remain part of my imaginations for I know that I could never be an Astronomer. Thanks for reading, anyway.
