What does your image show - Harvard University However, in November 1609 Galileo pointed his improved telescope with 20x magnification to the moon for the first time. (Simon Marius, a German astronomer, claimed he had discovered the moons first. The invention of the telescope played an important role in advancing our understanding of Earth's place in the cosmos. It's now understood that English astronomer Thomas Harriot, (1560-1621) made the first recorded observations of the Moon through a telescope, a month before Galileo in July of 1609. Galileo, however, was a believer, and Jupiter and its moons were proof that Aristotles model was wrong. Again, this showed that not everything in the heavens revolved around the Earth. These observations, only possible by the magnifying power of the telescope, clearly suggested that the Aristotelian idea of the Moon as a translucent perfect sphere (or as Dante had suggested an "eternal pearl") were wrong.

Explanation: #carryonlearning It was not possible back then to directly see this event because telescopes lacked the necessary optical technology to observe this phenomenon Galileo and the telescope - Explaining Science -- hydrogen atom(s) fuse to become one helium atom, and the total resulting helium has more/less -- than the total original hydrogen, electrons in atoms in Earth's atmosphere fall to lower levels. Three years later, in 1592, he moved to Padua, where, as professor of mathematics, he taught geometry, mechanics, and astronomy. Confusingly, nearly two and a half years later he observed the planet again and was surprised to see the moons had completely vanished.
