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

Greek Mythology in Astronomy The creatures and deities in Greek mythology are said to have connection with the astronomy and the star constellations. In this fragment of Hesiod’s poem “Nymphs like the Graces‚ Phaesyle and Coronis and rich-crowned Cleeia and lovely Phaeo and long-robed Eudora‚ whom the tribes of men upon the earth call Hyades.” (Hesiod‚ Homeric Hymns‚ Epic Cycle‚ Homerica. 1922) titled Astronomy‚ he mentioned and catalogued many of the constellations based on creatures and gods

Astronomy vs. Astrology This week we were asked to write a paper discussing the difference between astronomy and astrology. Astrology and astronomy grew up together throughout a large portion of human history. 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

I wanted to do Galileo because he is one of the most significant person of Astronomy. Galileo made a huge impact in Astronomy. “You can not teach a man anything; you can only help him find it within himself.” (BrainyQuote.com) That is Galileo’s most famous quote. He has invented a lot of things for example the telescope. Galileo was born February 15‚ 1564‚ in Pisa‚ Italy. He was the oldest of six children. He had three sisters and two brothers.He was one of the most significant person in the history

Introduction: Searching for extra-solar planets is not a very easy task. Because most of the times we find them by not actually looking at them but by the effects they produce mainly on the star around which they are rotating. It is because planets look like just a dull spec of light through a telescope. The distance between us and a nearby planet is very large. In our scale model it will be like looking at a dust particle in Thunder Bay Ontario if we are sitting in Halifax with our telescope. That’s

Q1) Last night you saw the star Betelgeuse exactly on your eastern horizon at 5:47 PM. Two students are discussing their answer to the question "At 5:47 PM tonight where will you see Betelgeuse?" Student #1: The Earth makes once complete rotation about its axis each day so Betelgeuse will rise at the same time every night. It will therefore be exactly on the eastern horizon. Student #2: No. The constellation Taurus rises earlier each month and so it must rise a little bit earlier each night. Betelgeuse

Astronomical Cycles and Their Effects on Planet Earth By Harry Mowat The orbit of the Moon around the sun The Moon orbits around the Earth every 27.3 days. The Moon’s orbit around the Earth is not a circular orbit but more of an eclipse and the orientation or the orbit is not fixed but differs in time. The Earth and the Moon are both actually orbiting the sun (the Moon at a much faster rate) but in the process of that orbit the Moon orbits Earth. This process is the main cause of tide formations
