and more humid regions. Overall‚ I think its offensive that the media has taken skin tone and weight and made them such superficial and dividing elements of physique. It doesn’t matter your weight or color‚ it’s the inside that is important and astronomy has helped me keep sight of that. In a greater sense it has also taught me

volcanoes that exist in the universe. However‚ one extraterrestrial volcano‚ perhaps the most commonly refered to extraterrestrial volcano‚ has developed a bit of name recognition over the years. Olympus Mons‚ one of the many volcanos found on Mars‚ is a giant shield volcano ("Mars | Volcano World | Oregon State University"‚ 2016). To give the phrase "giant sheild volcano" scale‚ Olympus Mons is 374 miles in diameter‚ meaning the extraterrestrial volcano is roughly the size of the state of Arizona

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

As debates rise over whether active SETI should be pursued‚ perhaps the debate should spend some time deciding what messages should be sent into space. Afterall‚ a large part of determining whether humans should actively seek for contact with extraterrestrials lies in deciding if the repercussions of such actions would be positive or negative to the human race; positive or negative that would be in large part due to the messages sent. The importance of the content of messages shows its significance

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

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

whether that star has planet(s) or not. The following methods are used for that purpose. 1. Astrometry 2. Radial Velocity Method 3. Pulsar Timing 4. Transit Method 5. Gravitational Microlensing Astrometry: This is the oldest method used to search extra-solar planets. This planet is basically used to find the mass of thee planet. This method is based on the gravitational effect of planet on its host star. As the planet rotates around its star‚ it applies gravitational force on the star and

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
