-
Galileo was an Italian astronomer, physicist, and mathematician. He improved the telescope and made observations that supported the Copernican heliocentric model. Galileo's discoveries, including the moons of Jupiter and the phases of Venus, challenged traditional astronomical beliefs.
-
Kepler, a German astronomer and mathematician, formulated three laws of planetary motion. His laws describe the elliptical orbits of planets around the Sun. Kepler's work laid the foundation for Isaac Newton's theory of universal gravitation.
-
Newton was an English physicist, mathematician, and astronomer. He formulated the laws of motion and the law of universal gravitation. Newton's work in celestial mechanics explained the motion of planets and objects in the universe.

Herschel was a German-born British astronomer. She discovered several comets and cataloged star clusters and nebulae. Caroline Herschel was the first woman to receive formal recognition for her scientific contributions.
-
Hubble was an American astronomer and cosmologist. He provided evidence for the expansion of the universe and formulated Hubble's Law. Hubble's observations helped establish the concept of the Big Bang and the existence of other galaxies.
-
Rubin, an American astronomer, provided evidence for the existence of dark matter. Her observations of galaxy rotation curves showed that galaxies were held together by unseen mass. Rubin's work revolutionized our understanding of the universe's composition.
-
Sagan, an American astronomer and science communicator, popularized astronomy through his TV series, "Cosmos." He conducted research on planetary science, exobiology, and the search for extraterrestrial life. Sagan's contributions inspired millions to develop an interest in astronomy and space exploration.

Ghez is an American astronomer known for her groundbreaking research on the center of the Milky Way. She led a team that provided strong evidence for the existence of a supermassive black hole at the galaxy's core. Ghez's work contributed significantly to our understanding of black holes and their role in galaxy formation.
