Extrasolar planet

1. How does the force of the Earth’s gravity 250 miles above the surface of the Earth compare to the force of gravity at the surface of the Earth? Is this surprising? The force of the Earth’s gravity 250 miles above has less pressure and less gravity because gravity pulls everything to the center of the Earth, so the farther the distance; the less gravity. The force of the Earth’s gravity 250 miles above the surface has about 90 percent of what the force of gravity is on Earth’s surface.…

Would you like to move to Mars? The problem in the article “Would You Move to Mars” by Lauren Tarshis, is that the Earth’s climate is changing. The NASA is trying to find clues that will make them find something living so the earth people can move to mars without wearing spacesuits. My opinion is that Earth is better than Mars, even though the climate on Earth is changing. There is a lot of reasons that I would not want to move to Mars, because it is not fun there. When you want to go outside…

in a Day by Ray Bradbury, the main conflict is between the children, William and Margot, and the people that assume responsibility for what happens during the story include the teacher, the classmates, William, and Margot. The children are on the planet Venus, where they are waiting for the Sun to appear for the first time in seven years. One girl, Margot, is from Earth, so she remembers the image of the Sun better than anyone else. This prompts envy among her peers, especially in a young boy…

would be regarded as humans, followed by macroscopic life, microscopic life, and abiotic systems such as stars, planets and molecules. Further presupposed by Bostrom, it would be arrogant to assume humanity is the pinnacle of intelligence, whereby it is certainly possible that life outside of…

The Earth is an ordinary planet speeding around an average star. Nothing at all is remarkable about it, except for the fact that it harbors life. Though millions of other planets with similar conditions to Earth exist, scientists have yet to find another planet occupied by any sort of intelligent beings. This led Enrico Fermi to pose the question, “Where is everybody?” (Fermi) Perhaps, the answer to this questions is that extraterrestrials exist, but simply undetected. Assuming that life…

described the motion of the planets across the sky. Kepler's 1st Law: The Law of Orbits, Kepler's 2nd Law: The Law of Areas, and Kepler’s 3rd Law: The Law of Periods. Kepler's laws were derived for orbits around the sun, but they apply to satellite orbits as well. In retrospect, the reason that the orbit of Mars was particularly difficult was that Copernicus had correctly placed the Sun at the center of the Solar System, but had erred in assuming the orbits of the planets to be circles. Thus,…

Neptune is one of the four large planets in our Solar System known as Gas Giants. It is the eighth planet in order from the Sun, and was seen through a telescope for the first time on the 23rd of September 1846. Keeping to the traditional naming system used for all the previous planets, Neptune was given its name based on the Roman god of the sea, in reference to Greek and Roman mythology. General Information: Neptune has a vivid blue colouration to its layer of cloud cover. Higher…

There hasn’t been any sun for seven years. How do you think you’d manage that? “All Summer in a Day” by Ray Bradbury is about several young children who have experienced just that. Margot, the protagonist of this chilling story, is the only child that remembers what the sun looked liked. Most of the kids were envious of Margot, making fun of her quite often. Margot eventually turns into a wallflower, a hopeful, but a dispirited little girl who knows she’s a bit different from the rest. This…

observed an intriguing celestial object that is known today as the Dumbbell Nebula or M27 as Messier named it in his catalogue of unclear nebulous objects. As many other similar objects were observed, astronomer noticed their similarity to the disk of a planet and that explains the reason behind their name, Planetary Nebulae (PNe). However, the nature of these objects stayed mysterious until 1864 when William Huggins was able to obtain the first spectrum of a PN, the Cat’s Eye Nebula. This…

this book was intimidating at first, deGrasse Tyson offers the easiest explanations of what he talks about. Such information the book contains are: the hunk of matter, we live on called Earth and its relationships to the sun, asteroids, and other planets. The book deGrasse Tyson writes also dives into the unknown world of dark matter and energy, light, what’s between the galaxies, and stars. Throughout the book, deGrasse Tyson explains how the spiritual beliefs people hold can be explained using…
