Explanation:

Galileo Galilei was the first to use a telescope for astronomical observations. In 1610, he observed the Milky Way and discovered that it is composed of a vast number of individual stars. Edwin Hubble is known for his work on galaxies and the expansion of the universe. Harlow Shapley studied the structure of the Milky Way (e.g., determining the Sun's position in it) but not the first telescopic survey of it as a collection of stars. Jill Tarter is involved in SETI (Search for Extraterrestrial Intelligence). Isaac Newton made contributions to physics (laws of motion, universal gravitation) and mathematics (calculus).
