Telescopes in Astronomy Once upon a time‚ we believed the Earth was at the center of our universe. We were seriously mistaken. We have come to find that at the center of most galaxies is a giant black hole that keeps everything together. With the use of telescopes‚ we have made it possible to see the “impossible”. We are able to see the geographic landscape of distant planets and moons. Telescopes have made it possible to measure the speed of light‚ understand gravity‚ and grasp other laws of physics

An adventure into Astronomy Late at night I like to go into my backyard with a telescope and look at the stars that far away in the night sky. The view of thousands of stars feeds me with wonder and amazement about both the stars origins‚ and what treasures they may hold floating around them. All life needs a host star to form around‚ and all life comes from the ashes of these once glorious masses of gas. Astronomy offers us a great view of the universe around us‚ you can join me and others‚

1. The parallax of the star 75 Leo is 0.10 and its apparent visual magnitude is +5.18. The absolute visual magnitude of 75 Leo is +5.14. 2. A G2 I star is larger in diameter and more luminous than the sun. 3. spectroscopic parallax can be used to determine the distance to a star when the spectrum of the star can be used to determine its spectral type and luminosity class. 4. Luminosity class IV objects are known as sub giants. 5. For stars

A Cyclic Universe: A New Model to Rival the Big Bang Theory Phys 1070- Astronomy Topical Essay Motivated by the M-theory‚ space-time ‘branes’ and extra-dimensions‚ scientists Paul J. Steinhardt and Neil Turok introduce a tantalizing alternative to the prevailing standard Big Bang-Inflation model of cosmology. Traditionally‚ the Big Bang-Inflation model features an explosive epoch 15 billion years ago when time and space sprung into existence followed by a fraction of a second of superluminal expansion

8. Meteorites What are impact craters? Impact Craters are depressions on many planetary surfaces. How are craters formed? They are formed by the impact of chunks of interplanetary matter (meteorites) striking the surface. Upon first impact‚ shock waves dissipate the energy of the meteorite through the ground. The ground is compressed rapidly and severely‚ and may be fractured‚ melted or vaporized Next‚ the surface is decompressed‚ and the material is flung violently out from the impact

Mercury : Due to mercury being extremely close to the sun‚ causes its planet to have no atmosphere. If any air was ever around Mercury‚ it would have been within its early years and from that point to now‚ it is gone because of all of the heat being given off of the sun. Mercury has crazy weather issues because of the lack of atmosphere‚ which includes a drastic weather change within day to night.Whenever the sun touches the surface of Mercury‚ that is when the climate reaches its highess at

However‚ the two have been separated for centuries‚ and because so many people mistakenly think that astrology is some kind of science‚ it often happens that the two are even today still confused with one another. Astronomy is the science of mapping the positions and movements of celestial
