Possibly the world's best-known astronomer, Galileo constructed a simple refracting telescope in 1610 and became the first person to use a spy-glass for astronomy.
The sheer number of stars, the rough surface of the Moon and sunspots astonished him..
Ancient Astronomy.
Astronomy is the study of space, celestial objects, and everything that isn't on Earth.
This includes the study of the movement of stars, where the Earth lies in relation to other planets and celestial objects, and what makes up stars and other planets.Jul 31, 2022.
Thousands of years ago, long before the advent of telescopes, ancient peoples may have used grave sites to enhance their view of the stars.
Thousands of years before astronomers used telescopes to peer at the stars, people may have climbed into dark, stone chambers to help focus their gaze..
All of the stars you can see with the unaided eye lie within about 4,000 light-years of us.
So, at most, you are seeing stars as they appeared 4,000 years ago..

"Because light takes time to get here from there, the farther away 'there' is the further in the past light left there and so we see all objects at some time in the past," explains Floyd Stecker of NASA's Goddard Space Flight Center in Greenbelt, Maryland..

Modern astronomy, astrophysics and cosmology changed beyond recognition over the post-WWII period. In 1945, astronomy meant optical astronomy and the tools of astronomy were optical telescopes. By the 1960s and 1970s however, astronomy was experiencing golden years of innovation and discovery.
People were interested in the celestial bodies and phenomena from the very beginning of humankind. The sunrises and sunsets, the phases of the Moon and the change of seasons were things that moved people to make astronomical discoveries, and this is how astronomy started to develop. Let’s take a dive into the fascinating history of astronomy.
Since then, the pace of advancement has crescendoed rather than slackened. When the history of science gets written, this amazing progress will be acclaimed as one of its greatest triumphs—up there with plate tectonics, the genome and the Standard Model of particle physics. And some major fields in astronomy are just getting going.
