Milky Ways/Galaxies

WALT take effective notes

My Topic: Milky Way/ Galaxies

Key Words:

Elliptical, hydrogen, Lenticular galaxies, irregular galaxies 

Interesting Facts: A Galaxie is a massive group of stars.

The Greek word galaxies means milky.

There could be 180 billion galaxies.

In a Huge galaxy there could be up to 10 trillion stars.

Our galaxie contains about 400 billion stars.

The largest local galaxie is the Andromedd.

Gravity can pull galaxies into new shapes

Any new questions I have:

How have they discovered it is spiral? What if it is not.

How come they called it the Milky Way?

Why do people call it spilled milk?

How come the Milky Way has so many planets and stars in it.

Who found out we were in the Milky Way?

Why do they think we are in the Milky Way? What if we are not?

Does the Milky Way move around or does it stay still?

How come you can not see other galaxy's they are so big?

In comparison what would be the Milky Way and what would we be a sand speck or and the Milky Way a tennis ball?
