The Milky Way and Beyond
Did you know our Solar System is just a tiny part of something much bigger? We live in a galaxy called the Milky Way, and it’s filled with stars, planets, and mysteries!
Let's explore the Milky Way!
Let’s take a journey through the Milky Way and discover what galaxies are, how they’re formed, and what makes them so amazing!
What is a Galaxy?
A galaxy is a giant group of stars, planets, gas, and dust, all held together by gravity. Inside a galaxy, there are also comets, asteroids, and even black holes! Galaxies come in all shapes and sizes—some look like spirals, while others are round or even messy blobs!
Meet the Milky Way
Our galaxy, the Milky Way, is shaped like a big, spinning disk with a bulge in the middle. If you could zoom way out into space, it might look like a glowing whirlpool! It’s so huge that even though light moves super-fast, it would still take 100,000 years for light to travel across the entire Milky Way!
Fun Fact: If you scaled the Milky Way down to the size of a dinner plate, our Solar System would be smaller than a tiny speck of dust!
Galaxies Everywhere!
The Milky Way isn’t alone. There are billions of galaxies in the universe! Some, like our neighbour the Andromeda Galaxy, are pretty close, while others are so far away, we can barely see them with telescopes. There are three main types of galaxies:
Spiral Galaxies: Like the Milky Way, with swirly arms and lots of stars.
Elliptical Galaxies: Round or oval-shaped, and full of older stars.
Irregular Galaxies: Messy and unshaped, like cosmic blobs!
How Do Galaxies Form?
Galaxies form when gas and dust come together over billions of years, slowly growing into massive collections of stars. Sometimes galaxies crash into each other and combine, creating even bigger galaxies!
Make Your Own Galaxy Model!
You can make a model of a spiral galaxy at home using a paper plate, some glitter, and a marker. Draw the swirly arms of the Milky Way on the plate, add stars with glitter, and put a black dot in the middle for the supermassive black hole!
