The first usage of X-ray telescopes for astronomy was for observing the Sun, the only X-ray source in the sky producing an abundance of signal. Because the Sun is so bright in X-rays, the focusing element can be small, and photographic film can be used as a detection medium. The first X-ray picture of t...

The original telescope as designed by Galileo and others helped people see farther and deeper into space. That was a great advantage, and its original discovery was one of the great accomplishments of our civilization. But the first telescopes only showed what is visible. As time went on, scientis...

In the 19th and early 20th centuries, advances in mirror making, glass production, and lens grinding led to the construction of increasingly larger and larger telescopes, which in turn led to the building of permanent structures to hold these huge instruments. At first these observatories were b...

Of course, those first telescopes weren't perfect. While distant objects did appear closer, they weren't very clear. It took several hundreds of years and a lot of experimentation to get really sharp images through telescopes. And people were always trying to see farther and farther into space, s...

Phoenicians cooking on sand discovered glass around 3500 BCE, but it took about 5,000 years more for glass to be shaped into a lens for the first telescope. Even cavemen must have noticed how water refracts, or bends, the image of objects below the surface, but this probably seemed specific to liquid...

To truly understand what the sky and its lights are all about, human beings eventually realized they couldn't just rely on their eyes. They had to develop tools to help explore what stretched far above them. The telescope was the key invention in the progress to modern astronomy, but it took many thou...

In 1868 Fizeau noted that the purpose of the arrangement of mirrors or glass lenses in a conventional telescope was simply to provide an approximation to a Fourier transform of the optical wave field entering the telescope.

The technology for producing lenses has been known from before recorded history. Early lenses were not made from glass, but carved and ground from rock crystal (quartz).

The credit for the invention of the telescope has been a subject of discussion. In 385 BCDemocritus announced that the Milky Way is composed of vast multitudes of stars[1].
