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)
Galileo Galilei invented the telescope, which revolutionized our understanding of the cosmos by allowing us to see distant objects more clearly and in greater detail. This tool played a crucial role in advancing astronomy and changing our perception of the universe.

Jons Jacob was the man to discover Selenium.
Galileo believed Venetians would be interested in the telescope due to their strong maritime culture and reliance on navigation. The telescope could enhance their ability to observe distant ships and identify potential threats or trade opportunities. Additionally, Venice's status as a center of trade and science made it a conducive environment for innovative technologies like the telescope. Galileo saw the device as a practical tool that could provide significant advantages in both commerce and defense.

they use space probes,satellites,and of coarse,telescopes.

All you have to know is who Galileo Galilei is. He is a man from thousands of years ago who studied space. I really don't know. I'm in 5 grade and this is what we are learning. Well, yo momma will tell ya
My dear friends its the telescope! That was the first instrument (tool) to use to study space and astronomy. For your information.. ( FYI) Galileo was the first man to invent and use the telescope. By the way I'm in the 5th grade but we learn a lot of good astronomy stuff in class. I'm pretty smart
The first tool used to observe space was the telescope, invented in the early 17th century. The earliest known version was created by Hans Lippershey in 1608, but it was Galileo Galilei who significantly improved the design and used it to observe celestial bodies like the moon and Jupiter's moons in 1609. This marked a pivotal moment in astronomy, allowing for detailed observations of the universe beyond the capabilities of the naked eye.
The very first tool used for space exploration was the telescope, invented in the early 17th century. Galileo Galilei famously used a telescope in 1609 to observe celestial bodies, including the Moon, Jupiter's moons, and the phases of Venus. This groundbreaking instrument allowed humans to expand their understanding of the cosmos and laid the foundation for future astronomical studies. The telescope marked the beginning of scientific inquiry into space beyond the observable limits of the naked eye.

A tool is something that helps you build or unbuild things.
It was used to remove penises from the male body.
A tool for pulling things out is a pry bar or a claw hammer.
A tool invented by Galileo (who invented telescope) to help his math students solve problems. Go to google images for picture.
