The universe is vast and filled with countless celestial objects. Our
Earth is just one small part of the solar system, which includes the
Sun, eight planets, moons, asteroids, and comets. 
Let us explore the wonders beyond our planet and understand how
Earth fits into the vast universe.
Scientists study space using telescopes and space missions to
learn more about planets, moons, and distant galaxies. 
At night, we can see stars and constellations like the Big Dipper
and Pole Star in the sky.

At night, we see many stars in the sky.
Some are bright, while others are dim.
Stars give off their own light.
Before modern technology and tools like
the magnetic compass, people,
especially sailors and travellers, used
stars to find their way at sea or on land.
Recognizing stars and their patterns was
very useful for navigation in ancient times.

c o n s t e l la t i o ns
Groups of stars sometimes form patterns
that look like familiar shapes. These groups
of stars that form patterns are called
constellations.
For example, one famous constellation is
Orion, which looks like a hunter. 
The stars in a constellation are often
connected by imaginary lines to make the
pattern easier to see

There are two famous star patterns called
the Big Dipper and the Little Dipper. 
A special star called the Pole Star, or
Polaris, is part of the Little Dipper. This
star is unique because it stays in the same
spot in the sky, always pointing North.
These are part of larger constellations, with
the Big Dipper being part of Ursa Major
and the Little Dipper part of Ursa Minor.
