The document discusses the different types of stars found in our galaxy, with around 90% being stable, healthy stars like our Sun. When viewing the night sky with the naked eye, we can see some of the larger, brighter stars that make up about 9% of stars, including giants that have exhausted their hydrogen fuel and hot, blue stars. The Kepler space telescope searched a small area of the galaxy roughly the size of Connecticut to hunt for exoplanets orbiting other stars.

Kepler would be
searching an area
about the size of
Connecticut.

Our whole Solar

would be this big
Imagine, if you shrunk our solar system to a little larger than a
quarter:
How big an area is that?
would span North
America.
