The invention of the telescope played an important role in advancing our understanding of Earth's place in the cosmos.
While there is evidence that the principles of telescopes were known in the late 16th century, the first telescopes were created in the Netherlands in 1608..
Time and other observations could be made with this dial using starlight using the positions of the stars.
Astrolabes, which could locate and predict the movement of heavenly bodies like the Moon, planets, and stars, were first developed in the 11th century BC and were refined throughout the ages..
History of telescopes can be traced all the way back to the 700 BC, where ancient empires of Assyrian, Egypt, Babylon and Greece all experimented with the lenses made from polished crystals..
Early Application:
The first astronomers created calendars from changes they saw in the Moon.
Some ancient people around 5,000 years ago set up large stones to mark the movement of the Sun and other stars.
One of those old observatories is Stonehenge in what we now call England..
The sundial dates back to early antiquity when it was a particularly prestigious instrument.
This instrument, which has constantly evolved over the centuries, both in its form, its precision and its uses, was mainly intended to indicate solar time.
It can also give the dates of the solstices and equinoxes..
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..
Origins of Astronomical Instruments: Ancient Astronomical Tools.
Ancient astronomers used a variety of ancient astronomical tools to identify and calculate astronomical phenomena and objects.
Some examples of astronomical instruments used by ancient astronomers include sundials, astrolabes, or quadrants and sextants..

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..
True astrolabes were made before 400 A.D. and were highly developed in the Islamic world by 800 A.D. and were introduced to Europe from Islamic Spain (al-Andalus) in the early 12th century.
The first astronomical clocks were built in the 13th century..

One extremely important reason ancient astronomy was significant was that it allowed ancient people and civilizations to keep track of the passage of the seasons.
This, by extension, meant they could better time when to plant or harvest crops..
Although the Warren Field calendar was actually discovered from the air in 1976, it was only unearthed by the National Trust for Scotland in 2004. Even so, it took us almost another decade to determine that it was something absolutely epic—“the beginnings of recorded time,” as an archaeological team from the University of Birmingham called it. The .
With its rings circling a central point, the armillary sphere was a distant relation to the celestial globe. There were two different types of spheres—observational and demonstrational. Ptolemy was one of the first people to use one. The rings were divided to allow the reader to turn them as well as to establish latitude and longitude. Along with a.
The celestial globe dates to a time when astronomers believed that the stars were on a globe of their own that circled the Earth. As that imagined globe moved, the stars moved, too. The celestial globes that were created to map that heavenly orb are absolutely stunning. Some of the earliest globes were made by the ancient Greeks, and the idea remai.
Also known as the Poetica Astronomica, Hyginus’s star atlas was one of the first depictions of the constellations. Although its authorship is debated, it is sometimes attributed to Gaius Julius Hyginus, who wrote between 64 BC and 17 AD. Others claim that the work has similarities to another piece by Ptolemy, suggesting that a different Hyginus wro.
The Chankillo astronomical site in Peru is so complex that we only discovered its true function in 2007 with the help of a computer program designed to align solar panels. Stretching 300 meters (980 ft) along the hilltop, the site is made up of 13 towers arranged in a straight line. As a fort, it was an incredibly poor choice of location, without d.
Named for the German town where it was discovered in 1999, the Nebra sky diskis the oldest depiction of the cosmos ever found. It had been buried alongside a chisel, two axes, two swords, and two arm rings. Although this Bronze Age burial site dates to about 3,600 years ago, researchers acknowledge that the artifacts may be even older. Clearly depi.
Sundials have been reduced to little more than kitschy garden accessories today. But at one time, they were necessary for telling time and tracking the movement of the Sun across the sky. One of the oldest sundials was found in the Valley of the Kings in Egypt. Dated to between 1550 BC and 1070 BC, this sundial is a piece of limestone with a semici.
Brought to Europe at the turn of the 14th century, the volvelle was a weird sort of astronomical instrument that remained one of the key tools for scientists and physicians. Layered circles of parchment were held together by a single tie in the center that allowed the user to move all of the circles to calculate everything from the Moon’s phases an.
Not much is known about Abu Mahmud Hamid ibn al-Khidr al-Khujandi, except that he was a mathematician and astronomer living in the area that’s now Afghanistan, Turkmenistan, and Uzbekistan. However, we do know that he was responsible for building one of the largest astronomical instruments of the era—the mural sextant near Rayy. The mural was done .
Amazingly
Some of these ancient scientific instruments have been preserved through the millenniaAnd can be visited today. Each provides a window into how our ancestors made sense of the world around them.

The Astrolabe
Considered the mathematical jewel of the Medieval Age
Was until the end of XVII century the primo astrological instrument. It also demonstrates the celestial mechanism and the apparent movement of the stars. Set for 41° latitude. 1.77″ in diameter. (Note:
The miniatures and keyrings are the same size device for each type.)
This ancient Chinese observatory contains early astronomical technology, including exotic instruments such as the azimuth theodolite and the armillary sphere, both used to measure stellar distances. These sacred hoops have been built by American Indians for as many as 5,000 years. Among other purposes, they served as astronomical calendars.

With the developments of ancient astronomy, ancient astronomical mechanical instruments were extensively used for measurements, computation, and demonstration. These instruments represented the combinational achievements of astronomy and mechanical engineering technology at the subjects’ eras.
