In this blog we are going to disscusing about what is astronomy tools, studying the universe and most importantly why we need to study universe so lets begin with the first.

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.
Astronomers use observatories equipped with powerful telescopes that help them magnify the view of dim and distant objects in the universe. 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 us Curiosity, Cassini Saturn Mission, and many many others. Those probes also carry instruments and cameras that provide data about their targets.
ok guys we reach to the most asking question why we need to study universe ……….
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.
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. We are a way for the universe to know itself.”
