Astronomy #4: Studying The Universe

“As you can see, astronomy turns out to be a complex subject and it requires several other scientific disciplines to help solve the mysteries of the cosmos.To do a proper study of astronomy topics, astronomers combine aspects of mathematics, chemistry, geology, biology, and physics.

The science of astronomy is broken into separate sub-disciplines. For example, planetary scientists study worlds (planets, moons, rings, asteroids, and comets) within our own solar system as well as those orbiting distant stars. Solar physicists focus on the Sun and its effects on the solar system. Their work also helps forecast solar activity such as flares, mass ejections, and sunspots.

Astrophysicists apply physics to the studies of stars and galaxies to explain exactly how they work. Radio astronomers use radio telescopes to study the radio frequencies given off by objects and processes in the universe. Ultraviolet, x-ray, gamma-ray, and infrared astronomy reveals the cosmos in other wavelengths of light. Astrometry is the science of measuring distances in space between objects. There are also mathematical astronomers who use numbers, calculations, computers, and statistics to explain what others observe in the cosmos. Finally, cosmologists study the universe as a whole to help explain its origin and evolution across nearly 14 billion years of time.”
