What is Astronomy All About?
One in the oldest sciences, astronomy can be a branch of science that deals with celestial objects such as stars, planets, comets, nebulae, and galaxies. It dates back towards time on the ancient Greeks, who sought to develop theories about the universe. Amateur astronomy can also be a fun hobby for those interested in what lies beyond the Earth.
You can find various fields within astronomy. These consist of cosmology, astrometry, planetology, radio astronomy, and mathematical astronomy. Cosmology refers to the study from the universe as a whole, including how the universe was formed. Astrometry refers for the review of excellent distances. Planetology refers towards analyze of planets within our solar system and other planets that orbit distant stars. Radio astronomy refers to the study of radio telescopes to investigate the universe. Mathematical astronomy refers on the analyze of the universe using numbers, calculations, and statistics.
Astronomers work closely with scientists in other related areas. For instance, astronomers may conduct research with experts from mathematics, chemistry, geology, biology, or physics. Some astronomers specialize inside the area of physics and are called astrophysicists.
Numerous astronomers have played a key role in advancing the field throughout the years. Some from the most well-known astronomers consist of Ptolemy, Galileo Galilei, Copernicus, Johannes Kepler, Tycho Brahe, Isaac Newton, Albert Einstein, William Herschel, Edmond Halley, Willem de Sitter, Edwin P. Hubble, Thomas Gold, Georges-Henri Lemaitre, Carl Sagan, and Stephen Hawking.
Amateur astronomers can make significant contributions on the field of astronomy. Some amateur astronomers choose to build their own equipment in order to observe space phenomena. They usually focus on exploring the moon, the planets, the stars, comets, meteor showers, as well as deep space objects like star clusters, galaxies, and nebulae. Amateur astrophotographers spend their time taking pictures on the sky at night. Quite a few amateur astronomers rely on conventional telescopes and radio telescopes to make their discoveries.
Astronomy continues to be a fascinating science that offers something for both amateurs and professionals.
