What 3 things did Galileo discover with his telescope?
What did Galileo discover?
- Craters and mountains on the Moon. The Moon’s surface was not smooth and perfect as received wisdom had claimed but rough, with mountains and craters whose shadows changed with the position of the Sun.
- The phases of Venus.
- Jupiter’s moons.
- The stars of the Milky Way.
- The first pendulum clock.
Why is Galileo’s telescope important?
While the scientific doctrine of the day held that space was perfect, unchanging environments created by God, Galileo’s telescope helped change that view. His studies and drawings showed the Moon had a rough, uneven surface that was pockmarked in some places, and was actually an imperfect sphere.
What telescope did Galileo invent?
Galileo’s Telescope: The first, which he constructed between June and July of 1609, was a three-powered spyglass, which he replaced by August with an eight-powered instrument that he presented to the Venetian Senate.
Who really invented the telescope?

When did Galileo invent the telescope?
1609
Galileo Galilei (1564-1642) was part of a small group of astronomers who turned telescopes towards the heavens. After hearing about the “Danish perspective glass” in 1609, Galileo constructed his own telescope.
What is Galileo’s proportional compass?
The sector, also known as a proportional compass or military compass, was a major calculating instrument in use from the end of the sixteenth century until the nineteenth century. It is an instrument consisting of two rulers of equal length joined by a hinge.

What did Galileo invent answer?
Galileo invented Thermometer in 1593. He discovered the thermometer with the help of the principle, which he had developed.
Why did Galileo invent the thermometer?
In 1593, Galileo Galilei invented a rudimentary water thermoscope, which for the first time allowed temperature variations to be measured. It was perhaps the first crude clinical thermometer, as it was designed to be placed in a patient’s mouth for temperature taking.
Hans Lippershey, credited with invention of the telescope. The first person to apply for a patent for a telescope was a Dutch eyeglass maker named Hans Lippershey (or Lipperhey). In 1608, Lippershey laid claim to a device that could magnify objects three times.
How did Galileo use the telescope?
Early telescopes such as Galileo’s were designed to use the principles of refraction, or the bending of light rays as they pass from one medium, such as air, into and out of another medium, such as glass. The convex objective lens, located at one end of the telescope’s tubular body, gathered the light from a distant object.
What was Galileo’s first telescope?
Galileo’s first telescope was basically a tube containing two lenses. His first attempt was a three-power instrument; this was followed by one that magnified objects approximately nine times. He showed the latter device to the Venetian senate, hoping to impress them with its commercial and military potential.
What telescope did Galileo use?
Galileo’s Telescopes. The basic tool that Galileo used was a crude refracting telescope. His initial version only magnified 8x but was soon refined to the 20x magnification he used for his observations for Sidereus nuncius. It had a convex objective lens and a concave eyepiece in a long tube.
