What is the difference between an astronomical telescope and a Galilean telescope?
A Galilean Telescope is also an Astronomical Telescope so it is just a subset of Astronomical Telescopes.
What is length of galilean telescope?
Galileo's telescope was about 92.7 centimeters long. 36.5 inches long.
Why were galilean moons the first objects to be seen with a telescope?
It was the first thing to be seen because that's how it was.
What did gallillao discover by using his telescope?
hediscovered the four moons of Jupiter, (soon named the Galilean moons).
What tool did Galileo use to discover things about space?
In his early career: No telescopes. A log to track planets. Sea-faring devices such as the sextant Later in life: In 1609 Galileo started using the telescope on the 'heavens' Kepler used the Galilean telescope until 1611 he re-invented the refracting telescope (now known as the Keplerian telescope)
Which planet has the Galilean moons orbiting around it?
Jupiter. The "Galilean" moons are the four largest moons, which are so large that Galileo was able to see them orbiting Jupiter even with his relatively modest telescope.
Who Improved the telescope and observed Jupiter's moons?
Galileo was the first to look at the planet Jupiter through a telescope, and to observe the moons of Jupiter (the 4 largest moons are still known as the Galilean moons).
What is so significant about the galilean moons?
They're fairly big for moons, although Jupiter itself is big. The four "Galilean" moons of Jupiter were the first "moons" other than our own Moon to be seen, by Galileo using his new telescope.
What tool do astronomers use to study space?
they use space probes,satellites,and of coarse,telescopes.
Was Galileo's telescope a reflector.?
No: Galileo's telescope was a Galilean refractor, which is to say it has a single large object lens at the top end and a concave eye lens at the other end. This is not a popular type of telescope now because it has a small field of view, and it is only used for cheap telescopes and opera glasses.
Why were the Galilean moons the first objects to be discovered with a telescope?
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!
Where did Galileo invent the telescope?
Galileo didn't actually invent the telescope, though he was one of the first to use it for astronomical observations. At the time he constructed his first telescopes, he was teaching at the University of Padua in Italy.
