SEEING STARS

The book starts with a question as to how many stars can we see with our naked eyes and that of a telescope.
It goes on with the information that stars look so small because they are very very far away. Also, they twinkle because we see them through air and dust.
Stars are made of hot gases that make the center of a star incredibly hot such as that of the sun. The sun is the closest star to our planet, but not the biggest or the hottest. It would take one over four months to reach Earth.
Chapter 2 of the book talks about the Milky Way. It explains how it got its name and what a galaxy is. Furthermore, it says that the shape of it is spiral. It provides information as well about the solar system. It says that the sun and the solar system travel around the center of the Milky Way. The Milky Way is just one of a hundred billion galaxies.
Chapter 3 deals with constellations and how they were used before as a compass and calendar to tell about direction and day, respectively. Some constellations can be seen a year and for others, all year long.
Chapter 4 enumerates the different kinds of constellations. Among those mentioned are, The Great Bear, The Big Dipper, the Little Bear, Cassiopeia, The Lion, The Swan, Pegasus, Orion, Pleiades and Taurus. For each of the constellation, the book provides a legend as to how each gets its name.
Finally there is a suggestion on how to go stargazing.
