Telescopes

Hans Lippershey

Dec 19, 1608

Hans Lippershey was the first to invent the spyglass. He was the first to present the idea of the telescope. His idea was denied and later Galileo worked with the design and improved it.

Galileo

Dec 19, 1609

Galileo built his own telescopes and used it to discover mountains and valleys on the moon. He worked based on Hans Lippeshey's idea and improved the idea.

Newton

Dec 20, 1680

Newtin built a metal-mirror reflector in the 1680's and then the first reflecting telescope was invented. The reason behind this is because metal mirrors prove an alternative method of gathering light.

Huygens

Dec 19, 1686

Huygen built an open-air telescope. He discovers that the bulges around Saturn are separate rings.

Hadley

Dec 20, 1721

1971 Hadley made a Gregorian reflector with a parabolic mirror. This reflector really improved the quality of the image.

Chester Moore Hall

Dec 20, 1729

Hall figured out how to use lenses of different shapes and different material. By discovering this, the images in the telescope improves.

Spiral Nebula are discovered

Dec 20, 1845

In 1845, Lord Rosse used a really large telescope to see the spiral structure of m51. Larger telescopes and larger mirrors allow one to see more things.

The frist photograph of the moon

Dec 20, 1847

Between 1847 and 1850, the first photo of the moon came from the telescope. With the Harvard Telescope. Data recording became more accurate.

Silver-on-Glass Mirror

Dec 20, 1850

In the 1850's, scientist figure out how to put silver on glass. This discovery made astronomers able to build more highly reflective telescope mirrors.

First permanent solar telescope

Dec 20, 1904

in 1904, The Snow Solar Telescope was built an then moved to Mount Wilson. New technology meant astronomers could learn the sun in that much more detail, and a new style of telescope was indeed needed.

Jansky

Dec 21, 1937

1932 to 1937, the first radio telescope was being built. Astronomers began to get a more complete view of the universe. This technology adavences in phone communication.

Russians

Dec 21, 1976

The Russians built the BTA, which was controlled and position by computers. Asronomers built smaller, more compact telescopes with larger primary mirror.

mulitple mirror telescope

Dec 21, 1979

in 1979, The first Telescope with multiple mirroes began observing. This technology allowed astronomers to combine many images to improve light-gathering ability.

Hubble Space

Dec 21, 1990

Hubble was the first visible-light telescope in space. This technology allowed atsronomers to move aboe the blurring effect of the atmosphere.
