-
Hans Lippershey creates the kijker (Looker), which can magnify up to three times. Zacharias Jansen creates the compound microscope.
-
Galileo makes his own version of a telescope, which magnifies up to 20 times, he drew the moon in detail and even studied the milky way.
-
Kepler developed the Keplerian telescope, it improved the magnification significantly but the images were upside down.
-
The new telescope which was enormous for the time, 12 foot, developed by Christian Huygens. The telescope helped him spot a moon which orbited Saturn which he named Saturni Luna.
-
Christian Huygens was able to give a detailed description of Saturn's ring.
-
Isaac Newton creates the Newtonian telescope, smaller easier and cheaper to build.
-
Chester Hall fixes the colour distortion which Isaac Newton had claimed was impossible. By studying the human eye, he had used refracting rather than reflecting telescopes.
-
William Herschel constructs a 12-meter telescope based on the Newtonian reflector telescope. Herschel solved the poor reflective quality often found in Newtonian telescopes.
-
The giant telescope was used by Lord Rosse for years to study the night sky.
-
Saturni Luna was renamed to Titan by John Herschel.
-
The Yerkes Observatory was meant to be the largest telescope in the world during its time.
-
The telescope Lord Rosse fell into disuse and was dismantled.
-
Radio Telescopy was developed by Karl Guthe Janksy, it was designed to receive a shortwave radio signal at around 20.5 MHz.
-
Bernard Lovell built a huge 250 foot radio telescope at Jodrell Bank in UK.
-
Lord Rosse's telescope was reconstructed.
-
The Hubble Space Telescope was deployed, making it the first telescope to be launched into space.
-
The Compton Gamma Ray Observatory was launched, it was sent to low earth orbit and consisted of 4 telescopes on a single platform.
-
The W. M. Keck Observatory was built from 1990-1996, a twin-telescope astronomical observatory near the summit in Mauna Kea in Hawaii.
-
The Compton Gamma Ray Observatory had it's deorbit.
-
The Herschel Space Observatory was built by the European Space Agency, it was the largest infrared telescope to ever be launched in space.
-
The new James Webb Space Telescope was built and will be replacing the Hubble Telescope.
-
The James Webb Space telescope will be launched.
