- : the study of objects and matter outside the earth's atmosphere and of their physical and chemical properties.
5 types of astronomy
Learn the Night Sky with the Unaided Eye
Astronomy is an outdoor nature hobby, so the best way to begin is to go out into the night and learn the starry names and patterns overhead.
Buy yourself an inexpensive planisphere, which shows the constellations visible at any time throughout the year..
Branches of astronomy
Astronomers study planets, stars, and other celestial bodies.
They use ground-based equipment, such as optical telescopes, and space-based equipment, such as the Hubble Space Telescope.
Some astronomers study distant galaxies and phenomena such as black holes and neutron stars..
How far can astronomers see?
We're looking back in time the further out we go because it takes time for light to travel to us.
So the furthest out we can see is about 46.5 billion light years away, which is crazy, but it also means you can look back into the past and try to figure out how the universe formed, which again, is what cosmologists do..
What can we learn from astronomy?
By studying the cosmos beyond our own planet, we can understand where we came from, where we are going, and how physics works under conditions which are impossible to recreate on Earth..

What do you mean by learning astronomy?
Astronomy is the study of everything in the universe beyond Earth's atmosphere.
That includes objects we can see with our naked eyes, like the Sun , the Moon , the planets, and the stars .
It also includes objects we can only see with telescopes or other instruments, like faraway galaxies and tiny particles..
What is astronomy distance?
Astronomical units, abbreviated AU, are a useful unit of measure within our solar system.
One AU is the distance from the Sun to Earth's orbit, which is about 93 million miles (150 million kilometers)..
What is it called when you study astronomy?
A scientist who studies the objects in the sky, including planets, galaxies, black holes, and stars, is called an astronomer.
These days, the terms astronomer and astrophysicist are used interchangeably, to talk about any physicist who specializes in celestial bodies and the forces that affect them..
What is the meaning of word astronomy?

Why do I want to learn astronomy?
By studying the cosmos beyond our own planet, we can understand where we came from, where we are going, and how physics works under conditions which are impossible to recreate on Earth.
In astronomy, the Universe is our laboratory.
Why is astronomy worth learning?
Astronomy helps us approach the big questions
It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe.” One of the most important aspects of astronomy is its ability to help us understand our place in the universe..
- Astronomy is the branch of science that studies the universe, the stars and the planets.
Astronomy combines aspects of maths and physics to study how the universe was formed and the celestial bodies that are contained within it.
It is the oldest of the natural sciences. - In the past, astronomy has been used to measure time, mark the seasons, and navigate the vast oceans.
As one of the oldest sciences astronomy is part of every culture's history and roots.
It inspires us with beautiful images and promises answers to the big questions.
