People across cultures have always been curious about
the stars, planets, moon, and sun. This interest has led
many inventors, scientists or even common people to
build something that would help see what is beyond the
clouds.
The telescope as we know it has passed through
massive transformation since it was first patented in
1608. Galileo constructed his own telescope and used it
to see the moon and its craters as well as the Milky
Way. He was the first to see the rings of Saturn and
some of Jupiter’s moons. Another famous scientist who
made other significant contributions to the
development of the telescope was Johannes Kepler.
Christian Huygens built he most powerful and colossal
telescope of his time in 1655 which could be used to
see and study the solar system in detail. Then, Isaac
Newton built the first reflecting telescope which was
smaller and more portable with the same power. By
1789 the first 6-meter long giant telescope was built
for astronomical observation to see Uranus and its
moons.
As technology and investigation advanced, telescopes
were improved and made possible to see more in
space. By 1845 the M51 nebula, a giant spiral cloud of dust and gas, was discovered. Radio telescopes
appeared on the scene, the images were much clearer and meteors could be seen. Finally, the most powerful
telescopes, Space telescopes, such as the Hubble, made it possible to see incredible images from outer space.
Hubble is going to be replaced soon by the James Webb Space telescope.
