Andres Cardoso 5/12/2017 ASTM 101 Ranking Task Paper In the Doppler shift ranking task‚ astronomers measure the spectrum of electromagnetic radiation of visible and radio from celestial bodies to determine many attributes of the stars and planets. Some of the attributes that can be observed from measuring the spectrum of electromagnetic radiation are Luminosity distance and Doppler shift. “The equipment work by measuring the wavelength of absorption lines‚ where the larger absorption line means

is the 10th brightest stars (11th as viewed from Earth). Hadar is a blue-white super giant in the constellation Centaurus (Cen). In about 4‚000 years‚ the motion of Alpha Centauri‚ who’s proper name is Rigel Kentaurus‚ will carry it close enough to Hadar that they will appear to be a magnificent double star. Because of the distance away from Earth that Alpha and Beta Centauri are (approximately 90 parsecs)‚ they will be an optical double. As they sit today‚ the two stars look like a pair of eyes

has been contained in a small space. The existence of black holes was first theorized by John Mitchell in 1783. Mitchell accepted Newton’s laws of gravity and suggested that light escaping from the surface of a star would have its speed reduced due to the gravitation pull of the star‚ and therefore if a star’s gravitation pull was strong enough even light would not be able to escape.[1] Using the approximate speed of light he reasoned that if an object was approximately 500 times the mass of the

The Earth and 7 other planets (plus dwarf planets‚ moons‚ asteroids‚ comets‚ etc) are in orbit around the Sun. The SUN and all these things in orbit around it‚ make up our "SOLAR SYSTEM". Everything stays in orbit around the Sun because of gravity. The SUN is a STAR. Energy is being produced inside it‚ due to NUCLEAR

girl and her father looking up at the stars on an autumn night‚ at a beach. Notice that Whitman approves of the father teaching his daughter astronomy. Whitman had very liberal ideas about education that were ahead of his time‚ the 19th century. She sees clouds engulf the stars‚ blocking her view. The voice of the poet reassures her that one‚ the stars will return‚ and two‚ a force exists that is even more eternal than the stars. Whitman really knows his stars. The astronomy in this poem is quite

Regal Carnation Hotel (Guam) Case Analysis Case Introduction The island of Guam is an unincorporated territory of the United States located in the Philippine Sea. Ruled by the Spanish until 1898‚ Guam was ceded to the United States and briefly occupied by Japan between 1941 and 1944. Of strategic significance during the Second World War‚ more than 18‚000 Japanese and 1‚800 U.S. marines died in the U.S. retaking of the island. Following the war‚ the Guam Organic Act of 1950 provided for

understand where planets come from‚ one has to first look at where the planets in our solar system came from. Does or did our star‚ the sun‚ have a circumstellar disk around it? the answer is believed to be yes. Scientists believe that a newly formed star is immediately surrounded by a relatively dense cloud of gas and dust. In 1965‚ A. Poveda stated‚ "That new stars are likely to be obscured by this envelope of gas and dust (1)." In 1967‚ Davidson and Harwit agreed with Poveda and then termed
