Astrophysics is a science that studies the composition of the Universe and all its elements such as stars, planets, nebulae and galaxies.

This is an experimental and theoretical science because of the comments being done and assumptions that are taking place. All this work is the work of astronomers.

History

One of the first examples of astronomy is the monument Stonehenge in Wiltshire England. He is considered a sort of observatory of the Neolithic era in which it was predicted stations.

In 1609 Galileo Galilei was the first to use the telescope for astronomical observations and create their own theories. He was condemned for not accepting the geocentric model of the Universe defended by the church.

A Galileo was followed by other great scholars such as Isaac Newton who was the creator of the law of gravity and Edmond Halley who studied the orbits of the planets.

The astrophysics as born with the first observation by J. Frauhofer in XIX, which found that the light from the Sun is able to reflect components of the atmosphere.

To this end, the light from the Sun must pass through a spectroscope that it is an instrument capable of breaking this light into colors that compose key. From this point on astrophysics is a big turnaround mainly due to technological and scientific advances.

Observatories

These are places where they can carry out observations of celestial phenomena. They tend to settle in areas with high and a warm climate in which there is no risk of cloudiness.

At present there has been sent away from Earth telescopes to facilitate the remarks such as the Hubble Space Telescope sent by NASA.

In Spain, there are many observatories, most of them are located in the Canary Islands and Andalusia. Some of them are, for example, the Teide Observatory and the Sierra Nevada.
