This document provides an overview of stars and galaxies. It discusses how stars are born from dense clouds of gas and dust called globules, and how their appearance is determined by temperature, with hotter stars appearing blue and cooler stars appearing red. The document notes that stars die when they run out of gas, with small stars fading away and large stars expanding into red giants. It then gives a brief introduction to galaxies, stating they are composed of stars, gas and dust, and that the Milky Way galaxy contains around 100 billion stars. The document concludes by mentioning there are different types of galaxies and thanking the reader.

3. STARS TEMPERATURE AND
COLORS
 The apperience of stars are acording to their
temperature: Hot stars are Blue, Medium stars are
yellow and cooler stars are red giants. When Red Giants
die completley they turn to black holes and sometimes
they leave little stars called white drwafts.

4. HOW STARS ARE BORN
They had found dark clouds called globules, a globule
grows as it’s gravity pulls sorounding matter into itself. As
the globule keeps getting larger and larger, it keeps up until
it begins to glow red in time in the core zooms up to ten
milloon kelvins. When that happens the core becomes hot
enough.That is called a Prootostar. And thats how a star is
born.

5. HOW AND WHY STARS DIE?
 Stars die when their supply of gass runs out, causing to
get their light run off. “ Little stars” fade away when
they die but a big star begins to die it starts to go cooler,
red and bigger. That is called a Red Giant . Eventually a
Red Giant pushes its outer layers into space. All is left is
a tiny star known as a white drwaft. A white dwarft is
very dense and heavy for their size. Their weight gives
ten a hube amount of weght. They can be very little but
weght very, very much.

7. THE STARS MOVE
 The stars, the same that the sun, they move even thow
some do it much quicker that sun king. Even thow, they
are far away that their movement is so little for to be
seen, exccept by the carefull observations, with a lot of
years of separation. During all our life and a simple view,
is almost impssible detect some change. One way of to
observe the movementof the stars is teking photos in
times separated and measuring the light change in the
position of the stars.

8. THE LIFE OF THE STARS

9. What's a galaxy ?
 Galaxies are sprawling space systems composed of dust,
gas, and countless stars. The number of galaxies cannot
be counted—the observable universe alone may contain
100 billion. Some of these distant systems are similar to
our own Milky Way galaxy, while others are quite
different.
 Galaxies with less than a billion stars are considered
"small galaxies." In our own galaxy, the sun is just one
of about 100 billion stars.

10. OUR GALAXYE
 The milky way is a galaxy that belongs to our solar
system, where is the planet earth . Is seen as a bright
silver band that crosses the space. This composed by a
nucleus, the flattened, which arising numerous arms in
spiral, one big number of stars and all type of
interstellral matter, like gas and powder. Measured about
100.000 years of light.
