Astronomy
The rising of a star above the horizon. The scientific study of the universe and the celestial bodies, gas, and dust within it. Astronomy includes observations and theories about the solar system, the stars, the galaxies, and the general structure of space. Astronomy also includes cosmology.
Tip Facts change daily in astronomy. Remember that when choosing a book to read, especially if you´re going to buy it. Books older than ten years old may be good for a science history buff, but not for someone who needs to know what is happening in the field right now. If you´re looking for up-to-the minute discoveries, a magazine or newspaper might be best. For current research interests, try to stick with books written in the 90s or later.
