Telescopes, were essentially discovered in 1609. Galileo and later Keppler were the first astronomers to use them. They caught on rapidly as observing instruments and for look out purposes., it took the optician's a while to correct the inverted view on some of them, but once done, they took off.
He Invented the telescope, so he could see the sky
The first telescope to be trained at the sky in about 1610 only had an aperture of about 25 mm. Beside Venus, the Moon and Jupiter there wasn't much that COULD be seen. The optical quality couldn't be very great. To see the four brightest (Galilean) moons of Jupiter was really a feat. Even Saturn came in so poorly that the rings were mistaken for jug handles!
James Cook was sent to observe the transit of Venus in 1769. Apart from observing and recording this phenomenon, Cook's exploration was strictly earthbound.
The only definite answer we know is that they were built to house dead pharoahs. It is speculated that they were built for intergalatic transport, to observe the night sky, weird stuff like that.

Galileo
Galileo is the first person that we know of who pointed his telescope up. Or at least, he was the first person who wrote about doing so.
He invented the telescope.
Galileo was the first astronomer to use a telescope to observe celestial objects in detail. This helped him make groundbreaking discoveries such as the moons of Jupiter and the phases of Venus, which provided strong evidence for the heliocentric model of the solar system.
the telescope was shining it was painted a sky blue and decorated with fake diamonds and rubies
a hubble space telescope
Galileo built the first telescope in 350BC. He used it to survey the night sky.
It would take at least 1,000,000 years for the Hubble Space Telescope to observe over the entire sky of 100 billion galaxies in the universe.
