invented the field of formal logic
, and he identified the various scientific disciplines and explored their relationships to each other. Aristotle was also a teacher and founded his own school in Athens, known as the Lyceum.
Why is Aristotle important in astronomy?
Aristotle came to be
known for putting forward the physical model of the heavens
. Ptolemy was also interested in deploying his model of the heavens to describe its physical reality. However, his most important work was the mathematical models and data he used for predicting the motion of heavenly bodies.
What did Aristotle believe about the elements?
He believed that the
four elements were hot, dry, wet, and cold
, which could then combine to form the elements that other philosophers believed in: earth, air, water, and fire. Aristotle born in 384 B.C. in Stagira, believed in 4 elements earth, air, fire, and water which he also called the “simple bodies”.

What did we discover in space?
Astronomers spotted the brightest light in the universe, found
new planets circling distant stars
, and detected a collision between a black hole and a neutron star that warped the fabric of space-time. In our own solar system, scientists also discovered new moons and evidence of violent collisions from the past.
