What kinds of tests did Galileo do with his telescope are still debated today.
- His interest in telescopes began in 1609, when he discovered the spyglass and began experimenting with its construction, grinding and polishing his own lenses to perfection. Because of his telescope, he was able to view with a magnification of eight or nine times, allowing him to discern the presence of mountains on the Moon and satellites orbiting the planet Jupiter.

What did Galileo not see?
What if I told you something you already knew? However, Galileo did not go entirely blind until he was 74 years old because he was staring at the Sun through his telescope. He always projected a picture of the Sun onto a flat surface, no matter where he was. Recall that, as Galileo discovered, you should never gaze straight at the Sun.
What did Galileo discover with his telescope?
A shocking discovery was made by Galileo when he directed his telescope towards Jupiter, the biggest planet in our solar system, with his telescope. The planet was surrounded by four “stars” in the sky. Within a few days, Galileo discovered that these “stars” were actually moons of Jupiter orbiting the planet. Galileo was intrigued by the Sun and used his telescope to learn more about it.
What planet did Galileo not discover?
A remarkable discovery was made by Galileo when he directed his telescope towards Jupiter, the biggest planet in our solar system, using his instrument. It was surrounded by four “stars” in the sky. Galileo discovered that these “stars” were actually moons of Jupiter orbiting the planet within a few days after their appearance on the planet. Galileo utilized his telescope to study more about the Sun because he was curious in what he saw.
Who discovered telescope?
Q. What did Galileo fail to notice? Mountains on the surface of the moon.
Who actually invented telescope 1608?
Although it is unclear who was the first to create the telescope, Dutch eyeglass manufacturer Hans Lippershey (or Lipperhey) was the first to patent it in 1608, making him the first person to do so. A kijker (“looker”) was Hans’ invention, and it was capable of magnifying images up to three times in size, according to Hans.
Who did Galileo show his telescope to?
Galileo Galilei demonstrating his telescope to Leonardo Donato in 1609 in a 19th-century picture illustrating the spread of the invention
How many of Jupiter’s moons did Galileo see with his first telescope?
Galileo Galilei, an Italian astronomer, made the discovery of four of Jupiter’s moons in January 1610, which are today known as Io, Europa, Ganymede, and Callisto. Initially, he referred to the various moons by their number designations: I, II, III, and IV.
Did Galileo invent telescope?
Galileo Galilei (1564-1642) was a member of a tiny group of astronomers who used telescopes to see into the stars during the Renaissance. It was in 1609 that Galileo learned about the “Danish perspective glass,” which inspired him to build his own telescope. A three-diameter object was magnified three times by the first telescope he built (and the Dutch ones that inspired it).
When did Galileo discover Jupiter?
Only one discovery has contributed to the demonstration that the Earth is not the center of the cosmos. Galileo Galilei, an Italian astronomer, used a telescope to view Jupiter on January 7, 1610, and discovered a ring of strange fixed stars around the planet.
How did Galileo build his telescope?
Galileo didn’t have any schematics to work from, so he had to rely on his own technique of trial and error to figure out where the lenses should go. It was convex and concave lenses in Galileo’s telescope, but today’s telescopes make use of two convex lenses (as opposed to two concave lenses in Galileo’s telescope).
