His observations of planetary motion, mostly that of Mars, gave important data for astronomers to come, like Kepler. This helped us construct our model of the solar system we use today. The calculation that if the Earth moves then the stars are at least 700
Basically their whole life depended on the stars. The Mayans used the stars to tell them when to go to war, harvest crops and other events of life. Astronomy is still in its use today especially because of the invention of the telescope by Galileo. Star spectrum is light coming from a star that is broken down into a rainbow. Spectra can tell us what makes up a star just by analyzing it.

Apollo 17 was the eleventh and final mission of the United States' Apollo program, the sixth mission to land humans on the Moon. Launched at 12:33 a.m. Eastern Standard Time (EST) on December 7, 1972, with a three-member crew consisting of Commander Eugene Cernan, Command Module Pilot Ronald Evans, and Lunar Module Pilot Harrison Schmitt, Apollo 17 remains the most recent manned Moon landing and the most recent crewed flight beyond low Earth orbit. After Apollo 17, extra Apollo spacecraft were used in the Skylab and Apollo-Soyuz Test Project programs. Apollo 17 was the sixth Apollo lunar landing, the first night launch of a U.S. human spaceflight and the final crewed launch of a Saturn V rocket. It was a "J-type mission", missions including three-day lunar surface stays, extended scientific capability, and the third Lunar Roving Vehicle.
Cooks first journey was in 1768 and his objective was to observe the plant Venus as it passed between the earth and the sun – this observation would help astronomers to calculate the distance of the sun from earth, he also hoped to find the southern continent. He visited Tahiti where he made observations of Venus, the Society Islands and New Zealand. He mapped most of the two main islands of New Zealand. His second expidition was to either discover the southern hemisphere or prove that it didnt exist. He went below 70 deg latitude that was the farthest any European had ever
The four largest of these were seen by Galileo when he made one of the first telescopes. The way they moved round the planet convinced him that the old idea, that everything moves round the Earth, must be wrong. The following was kindly contributed by Russell Odell The sun contains 99.9 percent of the mass in the solar system. The remaining 0.1 percent make up the other planets and their moons, and Jupiter took most of that mass. If Jupiter were a shell, all the other planets and their moons could fit inside with room to spare.
Leavitt’s discovery of the period-luminosity relation for Cepheid variable stars In the early 1900’s Henrietta Leavitt’s extensive research on Cepheid Variable stars enabled her to determine the relationship between the period and luminosity of stars to determine their distance from earth. Variable stars emit lights in different intensities and are also known as “lighthouse stars”. There is a direct relationship these stars have, which has a significant role in establishing the distance from earth, of stars that are in excess of 100 light years away (Mitchell, 1976, 162). This is the relationship between luminosity and the pulsation period of these stars. With luminosity being a measure of brightness and pulsation period being the time
More than 150 eruptions, most of which have produced fluid basaltic lava flows within the caldera, have been documented since the 17th century. The volcano is monitored by the Piton de la Fournaise Volcano Observatory, one of several operated by the Institut de Physique du Globe de Paris.

[3] The exhibits also included a twelve-inch (305 mm) Zeiss refracting telescope in the east dome, a triple-beam coelostat (solar telescope) in the west dome, and a thirty-eight foot relief model of the moon's north polar region. The Griffith Observatory after renovations,
Consequently, the study of the birth, life, and death of stars is central to the field of astronomy. ] (Netting, 2011) We explore the complexity of the stars and what astronomers use to determine fundamentals of their temprature, speed , rotation, and composition.
