Astronomy branches
There are two main types of astronomy, observational and theoretical astronomy.
Observational astronomy uses telescopes and cameras to observe or look at stars, galaxies and other astronomical objects.
Theoretical astronomy explains what we see.
It predicts what might happen..
Branches of astronomy
Astronomy has given us essential knowledge about the fundamental forces of the Universe in addition to multiple technology spin-offs and a large body of skills and technologies in optics, detectors, radio receivers and communications, which are essential to space travel..
Early astronomers
If this isn't enough, astronomy also deals with questions and ideas about things we can't even see, such as black holes and dark energy.
Astronomy has increased in popularity over the past two years..
How is astronomy used in everyday life?
Without astronomy, advances in x-ray imaging for the medical industry wouldn't have happened.
This includes many devices such as breast cancer, osteoporosis, heart disease, and dental x-rays.
The development of the charge-coupled device, CCDs, helped reduce exposure to x-rays..
How is astronomy useful?
Computers, satellites and the smartphones they service, Global Positioning System (GPS), energy-efficient solar panels, digital camera sensors, airport security scanners, portable X-ray machines, and Magnetic Resonance Imaging (MRI) scanners are just a few of technological advances that are the legacy of astronomy, and .

Things to learn in astronomy
American astronomer Carl Sagan (1934–1996) may not have been a great scientist in comparison to some on this list, but he is one of the most famous astronomers.
Sagan not only made important scientific studies in the fields of planetary science, he also managed to popularize astronomy, according to NASA Science..

Things to learn in astronomy
Astronomy is the study of everything in the universe beyond Earth's atmosphere.
That includes objects we can see with our naked eyes, like the Sun , the Moon , the planets, and the stars ..

Types of astronomy
NASA astronomers use several kinds of telescopes in space and on the ground.
Each observes targets like stars, planets, and galaxies, but captures different wavelengths of light using various techniques to add to our understanding of these cosmic phenomenon..
What did astronomers use?
Full-scale replica of an armillary sphere built and used by Danish astronomer Tycho Brahe in the late 1500s.
Armillary spheres large and small were used for centuries to study the sky and to teach about the celestial coordinate system, which astronomers used to locate objects in the sky..
What did early people use astronomy for?
People used this intricate knowledge of celestial objects and events to tell time and navigate, but they also used the stars and planets to tell stories, build societies, and most remarkably understand their own human relationship to the universe surrounding them..
What do we use for astronomy?
Telescopes and radio dishes are used from the surface of the Earth to study visible light, near infrared light, and radio waves.
Attached to these telescopes are various tools like special made CCD cameras, a wide variety of filters, photometers and spectrometers..
When was astronomy first used?
The first documented records of systematic astronomical observations date back to the Assyro-Babylonians around 1000 BCE.
From this cradle of civilisation in Mesopotamia – in the southern part of present-day Iraq – astronomers had built up knowledge of the celestial bodies and recorded their periodic motions..

Who first used astronomy?
Monitoring the motions of stars and planets in the sky was the best tool to track time, which was fundamental for agriculture, religious rituals and navigation.

Why astronomy is the oldest science?
Astronomy is the oldest science, with the first observations of the heavens conducted by our early human ancestors.
Historical records of astronomical measurements date back as far as Mesopotamia nearly 5000 years ago, with later observations made by the ancient Chinese, Babylonians, and Greeks..
Why do people use astronomy?
Throughout History humans have looked to the sky to navigate the vast oceans, to decide when to plant their crops and to answer questions of where we came from and how we got here.
It is a discipline that opens our eyes, gives context to our place in the Universe and that can reshape how we see the world..
Why do we use astronomy?
By studying the cosmos beyond our own planet, we can understand where we came from, where we are going, and how physics works under conditions which are impossible to recreate on Earth.
In astronomy, the Universe is our laboratory.
Why is astronomy used today?
Computers, satellites and the smartphones they service, Global Positioning System (GPS), energy-efficient solar panels, digital camera sensors, airport security scanners, portable X-ray machines, and Magnetic Resonance Imaging (MRI) scanners are just a few of technological advances that are the legacy of astronomy, and .
Why was astronomy invented?
Curiosity alone did not inspire the earliest astronomers: astronomy and astrometry were practical sciences too.
Monitoring the motions of stars and planets in the sky was the best tool to track time, which was fundamental for agriculture, religious rituals and navigation..
- Astronomers often use the astronomical unit to describe distances within solar systems because it is convenient and easier to understand.
The astronomical unit (au or AU) is defined as exactly 149,597,870,700 meters (about 93 million mi), which is roughly equal to the average distance between the Sun and Earth. - In Astronomy through the Ages, Sir Robert Wilson tells the story of how our understanding of the universe has evolved through history — of how the sedate and stable star field of ancient times has been replaced by the vast and explosive universe we know today.
