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 Italian who first used a telescope to study astronomy was Galileo Galilei, born in 1564, the same year as William Shakespeare. Galileo is renowned for his significant contributions to observational astronomy, including the discovery of the moons of Jupiter and the phases of Venus. His work laid the foundation for modern physics and astronomy, challenging the geocentric model of the universe.
Galileo first used the telescope to study planets in 1609, when he heard about the invention of the telescope in the Netherlands and built his own version of it. He observed the planets, including Jupiter and its moons, which led to significant advancements in the field of astronomy.

Galileo Galilei is credited with being the first to use a telescope to study the heavens systematically in the early 17th century. His observations of celestial bodies through the telescope led to significant discoveries in astronomy.
Most famously he improved the telescope. His studied Astronomy with his telescope.

If you have a reasonable telescope, and a chart of the skies, you can start astronomy (note spelling) now.
There are a number of instruments used in the study of astronomy. The telescope is best known, but instruments including satellites, radio waves and simple charts are all used in astronomy.
Robert Hooke was the first scientist to study plant cells.
