In classical Greece, astronomy was a branch of mathematics; astronomers sought to create geometrical models that could imitate the appearances of celestial motions. This tradition began with the Pythagoreans, who placed astronomy among the four mathematical arts (along with arithmetic, geometry, and music).

Or they could look at the Summer Triangle to know when Summer or Spring were coming as well. The stars allowed farmers to plan ahead and form agriculture, and constellations made it easier to recognize and interpret the patterns in the sky.
What is astronomy in simple words?
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 . It also includes objects we can only see with telescopes or other instruments, like faraway galaxies and tiny particles.
How did astronomy begin?
The Ancient Greeks developed astronomy, which they treated as a branch of mathematics, to a highly sophisticated level. The first geometrical, three-dimensional models to explain the apparent motion of the planets were developed in the 4th century BC by Eudoxus of Cnidus and Callippus of Cyzicus.
Who made discoveries in astronomy?
Galileo Galilei
The astronomer (also mathematician, physicist and philosopher) turned the new observational tool toward the heavens, where he discovered the four primary moons of Jupiter (now known as the Galilean moons), as well as the rings of Saturn.

What is the most important thing for astronomers to research?
They observe astronomical objects such as stars, planets, moons, comets and galaxies – in either observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, solar astronomy, the origin or evolution of stars, or the formation of galaxies.
Who discovered black holes?
Albert Einstein first predicted the existence of black holes in 1916, with his general theory of relativity. The term “black hole” was coined many years later in 1967 by American astronomer John Wheeler.
What are the importance of stars?
The reason why stars are so important is because they have helped humans navigate through Earth . When it was dark these stars would light up the sky giving people light . In addition stars are very important because they make life on Earth.
Why was the knowledge of the seasons so important to early farmers?
Early farming societies were at the mercy of the seasons. In order for a group of people to sustain a successful farming culture, they needed to come up with accurate ways of predicting when spring would occur (to know when to plant) and when the first frost could be expected (to know when to harvest).
How do scientists use constellations?
constellation, in astronomy, any of certain groupings of stars that were imagined—at least by those who named them—to form conspicuous configurations of objects or creatures in the sky. Constellations are useful in assisting astronomers and navigators to locate certain stars.

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.
What did Galileo Galilei do for astronomy?
Galileo sparked the birth of modern astronomy with his observations of the Moon, phases of Venus, moons around Jupiter, sunspots, and the news that seemingly countless individual stars make up the Milky Way Galaxy.
What astronomers do?
Astronomers study planets, stars, and other celestial bodies. They use ground-based equipment, such as optical telescopes, and space-based equipment, such as the Hubble Space Telescope. Some astronomers study distant galaxies and phenomena such as black holes and neutron stars.
Who discovered DNA?
Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.
Who invented the Internet?

White stars are hotter than red and yellow. Blue stars are the hottest stars of all.
How did hunter-gatherers use technology to improve their chances of survival?
How did hunter-gatherers use technology to improve their chances of survival? They were able to increase their food supply by inventing tools. They crafted special spears helping them kill game at greater distances. They used stone, bone, and wood to make more than 100 different tools.
How does the seasons affect agriculture?
Growing seasons will be longer. Increased temperatures could result in heat stress for some crops and increased yields for others. Changes in temperature may result in changing zones of crop production, so farmers may have to change the crops and crop varieties that they grow.
How did agriculture change the face of culture in the Fertile Crescent?
How did agriculture change the face of culture in the Fertile Crescent? (How did the ability to grow crops help them?) Growing crops better allowed them to feed themselves better and sell to each other, and they could stay in one area better instead of moving around looking for food.
Did the Greeks create the constellations?
The Greek constellations today
Astronomers officially recognize 88 constellations covering the entire sky in the northern and southern hemispheres. Among these 88 patterns listed in modern times, 48 constellations originated in ancient Greece.
How do ancient Greeks name stars within the constellation?
The ancient Greek tradition was to name stars by their position within a constellation. For example, Ptolemy refers to one star by the description “the reddish one on the southern eye,” a star we now know as Aldebaran in the constellation of Taurus the Bull. But these descriptions could get quite involved.
How have various cultures explained the constellation Gemini?
Gemini is Latin for “twins,” although the twins identified with the constellation depend on the culture, according to Encyclopedia Britannica. In Egyptian astrology, the constellation was identified with twin goats, while Arabian astrology said it was twin peacocks.
Why was astronomy important in the Renaissance?
