The name "telescope" was coined for Galileo's instrument by a Greek mathematician, Giovanni Demisiani, [182] [183] at a banquet held in 1611 by Prince Federico Cesi to make Galileo a member of his Accademia dei Lincei. [184] In 1610, he used a telescope at close range to magnify the parts of insects.
Galileo was an American robotic space program that studied the planet Jupiter and its moons, as well as several other Solar System bodies. Named after the Italian astronomer Galileo Galilei, the Galileo spacecraft consisted of an orbiter and an atmospheric entry probe.
He solicited suggestions for a more inspirational name for the project, and the most votes went to "Galileo" after Galileo Galilei, the first person to view Jupiter through a telescope. His 1610 discovery of what is now known as the Galilean moons orbiting Jupiter was important evidence of the Copernican model of the solar system.
The geocentric model held sway into the early modern age, but from the late 16th century onward, it was gradually superseded by the heliocentric model of Copernicus (1473–1543), Galileo (1564–1642), and Kepler (1571–1630). There was much resistance to the transition between these two theories, since for a long time the geocentric ...
Galileo began his telescopic observations in the later part of 1609, and by March 1610 was able to publish a small book, The Starry Messenger (Sidereus Nuncius), describing some of his discoveries: mountains on the Moon, lesser moons in orbit around Jupiter, and the resolution of what had been thought to be very cloudy masses in the sky (nebulae) into collections of stars too faint to see ...
If true, this might predate Galileo's discovery by around two millennia. [9] The observations of Simon Marius are another noted example of observation, and he later reported observing the moons in 1609. [10] However, because he did not publish these findings until after Galileo, there is a degree of uncertainty around his records. [10]
1602-1608 – Galileo Galilei experiments with pendulum motion and inclined planes; deduces his law of free fall; and discovers that projectiles travel along parabolic trajectories. [3] 1609 – Johannes Kepler announces his first two laws of planetary motion. [4] 1610 – Johannes Kepler states the dark night paradox. [5]
Galileo observed the Loki volcano (largest in the Solar System) and a new eruption in the southern region of the moon. I33 102 (63) 17 January 2002 This was the closest of all the flybys of Io. The moon provided a gravity-assist necessary for Galileo ' s ultimate collision course with Jupiter.
