to grind lenses. He invented the telescope and improved it further on. With his improved telescope‚ he could see ships in the sea two hours away. His telescopes were then supplied to the navy. Galileo then turned his telescope towards celestial objects. He observed the moon’s surface and saw that it was not as smooth as the naked eye saw it to be. The surface of the moon was actually uneven‚ rough‚ and full of cavities. He looked at Jupiter through his telescope and saw 3 stars aligned with the planet

the spyglass and the telescope. In 1609‚ Galileo built the first version of his telescope. He is often incorrectly credited with the invention of the first telescope. Galileo only improved the telescope and made his own. He modeled his telescope by the ones that were made in other parts of Europe. The first telescope was made by Hans Lippershey. The telescopes that were in other parts of Europe could magnify up to three times. Once Galileo Galilei heard about the telescope he started‚ right away

significant because Herschel sought information that was different than what other astronomers were studying at the time. What was the motivation that led to the discovery? William Herschel was frustrated with the small telescopes he was using. He couldn’t afford larger telescopes‚ so he built one himself. He was observing a Nebula when he discovered Uranus. What questions were asked? How can he see it? What if it is a planet? What are we going to name it? What did his work do for England?

for being out of bed. But then again‚ Filch is a bit of an idiot. We headed up to the top of the astronomy tower‚ glancing at the lunar chart Professor Turing had posted to be sure that it was’t a full moon. Thankfully‚ it wasn’t. We carried our telescopes‚ secure in their bags with the lens caps fasted on‚ to the top of the tower. We both wanted to run outside and start searching the sky for planets‚ but‚ of course‚ we had to wait for them to cool down. While we waited for the ten minutes to pass

CH 2 -According to Aristotle‚ larger‚ heavier objects were supposed to fall to the ground faster than smaller‚ lighter objects. Galileo performed a number of experiments to Aristotle’s pronouncements‚ that two objects of different weight dropped from the same height fall down at exactly the same rate. -Copernicus published his findings in 1543‚ the same years as his death‚ in a text entitled (On the Revolutions of the Celestial Spheres). -Heliocentric theory was proposed by Aristarchus of Samos

radio waves are larger than optical waves‚ radio telescopes work differently than telescopes that we use for visible > light (optical telescopes). Radio telescopes are dishes made out of conducting metal that reflect radio waves to a focus point. Because the wavelengths of radio light are so large‚ a radio telescope must be physically larger than an optical telescope to be able to make images of comparable clarity. For example‚ the Parkes radio telescope‚ which has a dish 64 meters wide‚ cannot give

His advanced instrument allowed him to view things no one before him had seen (Westfall‚ 1985). Using the newly improved telescope he discovered Jupiter’s four largest moons‚ the rings of Saturn‚ the phases of Venus‚ and the irregular moon (Galileo‚ 2010). He took his eye to the heavens because he wanted to provide evidence of interpretation of the Bible. However‚ his sightings

Allan Rex Sandage was an American observational cosmologist‚ who seen as one of the most influential astronomers of the 20th century. He rightfully earned the nicknames “Mr. Cosmology” and the “Super Hubble”‚ as continued and refined the work of Edwin Hubble and made many discoveries of his own along they way‚ including discovering the first quasar and producing the first reasonable estimate for the Hubble Constant (h0). Throughout his career‚ some of Sandage’s notable awards include the Helen B

NASA has found many planets out of our solar system. Those planets are called exoplanets. In addition‚Nasa has confirmed 3‚397 exoplanets And also 2‚531 other solar systems. NASA has launched a telescope into space and it is called spitzer. Therefore‚ using the spitzer telescope to find a lot more exoplanets. There is a lot of exoplanets outside our solar system and NASA plans to find a lot more. Some astronomers say that people may be able to live on other planets that are the same size as
