Is astronomy the fifth wheel?

Many people see astronomy as the fifth wheel in physics. And it’s true. But we are the steering wheel!

Was astronomy always science based?

Astronomy was not always science-based. As soon as science found its way into astronomy and supplanted astrology, physics was the natural branch of science to described the objects observed in the sky. Advances in optics made the science of astronomy actually possible early on and able to grow steadily for 400 years. Physics principles were readily applied to understand orbital motion of planets which you may have heard as Kepler’s Laws. The estimation of distances using brightness was made possible by inverse square equations. The separation of light into a spectrum (spectroscopy) made it possible to identify elements from afar as well as detect the expansion of the universe by Doppler shift. Without physics and the scienticic method, astronomy would solely be rooted in myths and supertition.

What are some questions you want to study in astronomy?

Why Study Astronomy?

Looking at the stars and galaxies helps us understand how our universe came into being and how it works. For example, knowledge of the Sun helps explain stars. Studying other stars gives insight into how the Sun works. As we study more distant stars, we learn more about the Milky Way. Mapping our galaxy tells us about its history and what conditions existed that helped our solar system form. Charting other galaxies as far as we can detect teaches lessons about the larger cosmos.There is always something to learn in astronomy. Each object and event tells a tale of cosmic history.

What are the disciplines of astronomy?

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.

What are the main targets that astronomers study?

So, what are the main targets that astronomers study? Let's start with stars — the heart of astronomy studies. Our Sun is a star, one of perhaps a trillion stars in the Milky Way Galaxy.The galaxy itself is one of countless galaxies in the universe. Each one contains huge populations of stars. Galaxies themselves are collected together into clusters and superclusters that make up what astronomers call the "large-scale structure of the universe".

What do astronomers study?

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.

How do astronomers use telescopes?

Astronomers use observatories equipped with powerful telescopes that help them magnify the view of dim and distant objects in the universe. Astronomy tools, like the armillary sphere, were used by early astronomers and new tools came about as the study of astronomy evolved. They also use instruments called spectrographs that dissect the light from stars, planets, galaxies, and nebulae, and reveal more details about how they work. Specialized light meters (called photometers) help them measure the varying stellar brightnesses. Well-equipped observatories are scattered around the planet. They also orbit high above Earth's surface, with such spacecraft as Hubble Space Telescope providing clear images and data from space. To study distant worlds, planetary scientists send spacecraft on long-term expeditions, Mars landers such as Curiosity, Cassini Saturn mission, and many, many others. Those probes also carry instruments and cameras that provide data about their targets.

What does astronomy tell us about the universe?

Each object and event tells a tale of cosmic history. In a very real sense, astronomy gives us a sense of our place in the universe. The late astronomer Carl Sagan put it very succinctly when he stated, "The cosmos is within us. We are made of star-stuff.

How did astronomy start?

That's actually how it got started — by people looking at the sky and charting what they saw. "Astronomy" comes from two old Greek terms astron for "star" and nomia for "law", or "laws of the stars".
