Galileo sparked the birth of modern astronomy with his observations of
the Moon, phases of Venus
, moons around Jupiter, sunspots, and the news that seemingly countless individual stars make up the Milky Way Galaxy.
Why is Galileo important to astronomy?
Galileo pioneered the use of the telescope for observing the night sky
. His discoveries undermined traditional ideas about a perfect and unchanging cosmos with the Earth at its centre.
How did Galileo influence astronomy?
He subsequently used his
newly invented telescope to discover four of the moons circling Jupiter
, to study Saturn, to observe the phases of Venus, and to study sunspots on the Sun. Galileo’s observations strengthened his belief in Copernicus’ theory that Earth and all other planets revolve around the Sun.
What did Galileo discover in astronomy?
Of all of his telescope discoveries, he is perhaps most known for his discovery of
the four most massive moons of Jupiter
, now known as the Galilean moons: Io, Ganymede, Europa and Callisto. When NASA sent a mission to Jupiter in the 1990s, it was called Galileo in honor of the famed astronomer.
In what ways did Galileo contribute to astronomy and physics?
With his unprecedentedly powerful telescopes, Galileo was the first to observe the uneven,
cratered surface of the moon
; Jupiter’s four largest satellites, dubbed the Galilean moons; dark spots on the surface of the sun, known as sunspots; and the phases of Venus.

How did Galileo impact the modern world?
He helped created modern astronomy
Galileo
turned his new, high-powered telescope to the sky
. … Galileo also observed the phases of planet Venus and the existence of far more stars in the Milky Way that weren’t visible to the naked eye.
Who first discovered heliocentrism?
And when it comes to astronomy, the most influential scholar was definitely
Nicolaus Copernicus
, the man credited with the creation of the Heliocentric model of the universe.
Who first discovered the planets?
PLANET DIST. FROM SUN (A.U.) ORBIT PERIOD (EARTH-YEARS) | Neptune 30.11 164.79 | Pluto 39.44 248.5 |

Who discovered the moon?
Galileo’s
discovery
When the moon was named, people only knew about our moon. That all changed in 1610 when an Italian astronomer called Galileo Galilei discovered what we now know are the four largest moons of Jupiter.
Who discovered the Earth?
Eratosthenes
then measured the angle of a shadow cast by a stick at noon on the summer solstice in Alexandria, and found it made an angle of about 7.2 degrees, or about 1/50 of a complete circle. He realized that if he knew the distance from Alexandria to Syene, he could easily calculate the circumference of Earth.
What was Albert Einstein’s contribution to society?
In addition to his work on relativity, the physicist laid the scientific foundations for paper towels, lasers, and more common products. Albert Einstein is justly famous for devising his
theory of relativity
, which revolutionized our understanding of space, time, gravity, and the universe.
Why is Galileo called the father of modern science?
Galileo is often considered the father of modern science
because his ideas were not derived from thought and reason alone
. He used the guidance of nature (experiments). This marked a revolutionary change in science—observational experience became the key method for discovering nature’s rules.
What three advancements is Galileo credited with?
Galileo’s discoveries about
the Moon, Jupiter’s moons, Venus, and sunspots
supported the idea that the Sun – not the Earth – was the center of the Universe, as was commonly believed at the time. Galileo’s work laid the foundation for today’s modern space probes and telescopes.
