He was on to a brilliant idea about how parallax can be used to estimate some astronomical distances.
Galileo was unable to resolve the rings of Saturn as individual objects with his telescope. They appeared to him as "ears" or handles attached to the planet. The true nature of Saturn's rings was not understood until later observations with more powerful telescopes.
Galileo Galilei was born in Pisa, Italy, in 1564, so he was Italian.
The Parallax View was created on 1974-06-14.
The parallax effect becomes unnoticeable after 1,000 light years.
Parallax Error Beheads You was created on 2008-10-20.
astoronomy
The Jovian moons. Galileo had little evidence for the heliocentric theory, which was later (in the 18th century) generally accepted as correct after the laws of motion and the law of gravity showed that the Sun is by far the most massive object in the solar system and therefore must be at the centre. Galileo did not have the other major piece of evidence supporting the heliocentric theory, which is the parallax shown by relatively close stars as the Earth moves round its orbit. Parallax is extremely small and was impossible to observe in Galileo's time, and this was used to support the idea that the Earth is at the centre. Bessel made the first measurements of parallax in the 19th century.

parallax is a planet
Galileo I am not so sure he was the first, but he is the most famous.
they look at the star in, say, spring, then fall or summer then winter. we have to be on opposite sides of the star to see the parallax, so it takes about a year
So Galileo was this really cool guy that had something to deal with space.
Because Galileo had first contemplated a career in medicine but he didn't like working that job, but he had became interested in mathematics after attending a lecture on geometry. He followed a teaching career that began in Florence and he was later appointed chair of the Mathematics Department at the University of Pisa in 1589.
Parallax - comics - was created in 1994.
Parallax Software was created in 1993.
Advent Parallax was created in 2008.
Parallax bars are used in photogrammetry and remote sensing. with the use of the principles of parallax and refraction, parallax bars are used to measure the heights of buildings and other features.
