Galaxy


Bits of paper--a cartoony spiral galaxy

Hi.

Use your imagination again, please.

I re-arranged some cartoon bits of paper "STARS" on a black "space" background to look like a twisty loop of STARS.

This swirling group of STARS represents a GALAXY of STARS. (And remember every STAR is REALLY a SUN--just like our sun except very, very, very far away.

The MILKY WAY is our GALAXY--and our SUN is one of the many, many, many STARS in our GALAXY.

You can see LOTS of other GALAXIES when you look into space on a dark night, but they are SO FAR AWAY that usually they look just like tiny points of light--in fact--they look just like STARS .

Curious scientists have built powerful TELESCOPES to look at some of these other GALAXIES and they have discovered that there are thousands and millions of them.

They have never seen the end of them.

So there does not seem to be any end to space.

There are more galaxies and stars than anyone can count!

And they all SUNS and some other dark stuff that not even the smartest scientists know much about!

Maybe the adult reading you this will take you outside to show you some of the most interesting things about the night sky and maybe you will even look at some of the STARS and galaxies in a telescope!

THAT IS INTERESTING!
