Who was the first person to build an astronomy radio telescope?
Karl Janksy, a Belll Labs engineer, develloped a sort of rotating antenna device- resembling a movable bridge-not a radar dish, some time in the thirties, the idea of possubly tuining in on intelligent lilfe from out there fueled the popular radio magazines- such as short wave craft, Mr. Gernsback had some wild ideas- but was correct that Radio contact was far more likely-0 cheaper ( but no $l2.50 ham receiver in depression dollars) , and probably safer than the experiments of Goddard ( rocket scientist who also had patents on the Tunnel that bears his name and is l00 years old this year! Open for l00 years , started in l905. completed in l9l0.
2009 is being celebrated as the international year of astronomy in honor of something that happened 400 years back What?
Many historians explain that Galileo was the first person to use a telescope. In 1610 Galileo discovered Saturn's rings. He also observed Jupiter's four moons and viewed the different phases of Venus. This lead to the study of sunspots and various celestial activities. Even though Galileo is credited with being the first to make practical improvements and enhancements to the use of the telescope, he was not the inventor, and therefore not the first person…
He built his first telescope and started to make observations. He discovered the phases of Venus and sunspots. He built his first telescope in 1609. Galileo's taught mathematics and actually made a few discoveries in physics. When he heard about the inventor of the telescope and he wanted to improve it.
Which italian scientist born in the 16th developed telescopes and used then to make revolutionary observations about your solar system?
None of them. The first telescopes were developed in 1608 by three Dutch opticians. You may have been thinking of Galileo, who built his telescope based on their descriptions, and who may have been the first person to use a telescope to observe the stars. His observations of Jupiter the following year did revolutionize astronomy.
