Analysis of our Solar System
Analysis of our Solar System On a hot summer night, as you are sitting outside enjoying the evening, you tilt your head back and look into the night sky. You begin to wonder what is really out there? How far away are the stars? Are they stars or are they planets? We live in a part of the night sky called the "Milky Way Galaxy." Our galaxy can be seen with the naked eye on a clear summer night. It resembles a ribbon stretched across the night sky. During the summer is when the Milky Way is at its fullest with the stars so clustered together they look like one white mass. Our galaxy is a gigantic agglomeration of stars and planets whose numbers will probably never been known. Currently we estimate this number to be about thirty billion. Scientists have estimated that the radius of our galaxy if it were to be travelled, would take us about fifty thousand light years and the thickness to be about fifteen to twenty light years. We live in small part of the Milky Way Galaxy, which is referred to as a solar system. Our solar system is made up of nine planets and 31 moons, which orbit the centre of galaxy. At the centre of our galaxy is our Sun, which is approximately twenty-five thousand light years from our solar system. These nine major planets in order from the centre are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Mercury is the planet

A geo-stationary orbit is when the satellite appears to be stationary. It is when the satellite is always in the same position in respect to the Earth. 3a) A comet is a mixture of ices and dust, that for some reason did not become planets when the Solar System was formed. Comets are invisible, except when they pass near the Sun and have highly eccentric orbits, and can often disappear for millennia at a time. They have long tails, made up of plasma and dust sized particles that can stretch for up to 10 million km. b) Comets have highly eccentric orbits, which can take them far beyond Pluto. Sometimes they will be seen, and then disappear for thousands of years before being sighted again. c) Comets travel fastest nearest the Sun, often travelling up to 15 miles a second. 4a) The Sun produces energy through nuclear fusion. This is when hydrogen atoms are

When one begins to study satellites he or she is bound to find out that orbits are an important part of the whole study. An orbit is the path of a body through space and has many functions. An orbit is what keeps a satellite alive. They control the speed, distance, and the height of where a satellite is and how long it will remain there. There are so many basic questions out there about launching satellites and what happens after they are launched. Learning about orbits will help one answer these questions and at the same time will give him or her better understanding of how they work. Types of orbit There are many types of orbits and they work in a variety of ways. One type of orbit is known as a north-south orbit. These orbits are also called polar orbits because they pass near the north and south poles. With a polar orbit a satellite will be able to pass every spot on the earth's surface. This fact makes them a favorite for military spy satellites. There are two other important types of orbits and they are known as synchronous orbits. Synchronous simply means "matched in time." A geosynchronous orbit is always directly above the equator. The orbit time is matched in time with the spin of the earth. A sun-synchronous orbit circles the earth in a north-south direction. Each time the satellite passes overhead the sun is always in the same position. There are many other types
Star Wars: The Phantom Menace.
Star Wars: The Phantom Menace: (1999, Rated , 133min, Twentieth Century Fox, Directed by George Lucas; Cast: Liam Neeson, Jake Lloyd, Natalie Portman, Ewan McGregor, Pernilla August, Samuel L. Jackson, Ray Park. Voices: Ahmed Best, Frank Oz, Anthony Daniels, Kenny Baker). 'Star Wars', when you hear or read that name, what comes to your mind? Adventure and excitement, dazzling special effects, which is enough to send your jaw dropping. Star Wars is one of the all-time classic movies, which people love. The original trilogy somehow captured viewers' imagination like no other movie possibly could, taking them on a wild ride through spectacular places and meeting unforgettable characters and creatures. George Lucas surprised us all by producing a collection of great films and now after all these years he surprised us again by making a new film. "Star Wars: Episode 1--The Phantom Menace," set many years before the goings-on in the original trilogy. This is when the evil Darth Vader is nine-years old. Star Wars fans across the nation waited sixteen years this and they shouldn't be disappointed as I thought that it was a great movie. "The Phantom Menace" is that it is perhaps the most visually astounding motion picture I have ever seen, far more exciting than the previous "Star Wars" movies, due to excessive visual effects. Words really can't describe the visual experience of
The Universe and Nuclear Fusion
Physics Homework – Nuclear Fusion Mrs Smirk Martha Brown Nuclear Fusion . What was the Big Bang? The big bang is the theory that once upon a time all the matter in the entire universe was compacted into one single small ball. The ball then exploded and shattered apart, throwing matter all across space and time. This theory is supported by the fact we know that all the galaxies are moving away from us faster and faster. The further away it goes the faster it gets. This makes us believe that the matter is still moving from the original explosion. . What is background radiation and what does it show? Background radiation, is just that – radiation in the background. It comes from all sorts of things like rocks, certain food sources, buildings and even that which is manufactured by us through various industries using it. Different types of radiation come from different parts of the world as there are different rock forms and bases. You also get cosmic rays of background radiation from the sun. . Describe in detail the life of a star Birth A star starts off as a cloud of dust and gas (specifically hydrogen). The cloud starts to clump together due to gravity. The cloud gathers together over thousands of years and spins slowly. The fast rotational force causes heat energy to form and increase the energy of the whole structure. As the heat increase and the
Production of Electricity Through Trash
________________ Introduction Currently, the world is facing a huge demand for electricity and companies are not able to produce enough to meet that demand. That is why we face power cuts. The reason why companies are not able to keep up with the demand is that we are running out of non-renewable sources. Our main source, oil, will run out in the next 50 years. Soon we will have to change to renewable sources. There are many renewable sources that we could depend on but they all have drawbacks. The advantage of using renewable sources is that they do not pollute the environment. Converting trash into electricity is a brilliant idea as it solves many problems at once. It helps us reduce pollution, the amount of land taken up by landfills and also the energy shortage. It is one of the simplest ways to recycle trash and lots people can help by giving their trash. Types of Trash Trash is anything that we discard or no longer have any use for. There are many types of trash and they are mainly categorized into these 5 types. . Biodegradable waste: This includes things like kitchen waste, food, vegetable peelings and paper. 2. Recyclable materials: Paper is also included into this group but other non-biodegradable items such as plastic, glass and metals fall into this. 3. Inert waste: These are materials that are not necessarily harmful to all species but they are harmful to
Planning for Lunar Observations Coursework
Astronomy Coursework-Planning In this coursework I will be observing the moon and its lunar features. I will observe over a number of dates and draw/replicate the image I see as accurately and precisely as possible. When drawing my observation I will be clearly highlighting major features such as the Kepler Crater, the Sea of Crises and the Caucasus Mountains. Plan/Design I hope to do my observations every day. This is because as my data will not be completely accurate (as these observations are made by naked eye, and not using any equipment such as binoculars, telescopes of cameras) so I will not be able to cross-check my information, so any in-accuracies in my data will hopefully be corrected and thus my overall end result will be more reliable. As stated before, I will produce labelled drawings for each evening showing all lunar features seen with the naked eye. My observations will be taken at both Norwich, England (Lat 52.6500° N, Long 1.2800° E) and Darmstadt, Germany (Lat 49.8667° N, 8.6500° E). All my observations will be taken in the Northern Hemisphere. Unfortunately I will not be able to go to any major close hills and the countryside on all of my observations, however on some I will be able to get quite far away from houses and any light pollution and obscuring objects. At the time of my observations I will assess the light pollution on the Antoniadi
Physics - Meteorite Craters Research
Research – Impact Craters The Meaning of Asteroid and Meteorite Asteroids are rocky or metallic objects mainly found orbiting the Sun in a region called the asteroid belt between Mars and Jupiter. Some are large - the biggest is Ceres with a diameter of nearly 600 miles (950km) - and are sometimes called minor planets or planetoids. There are millions of small asteroids. It is thought that asteroids are material leftover from the time that the planets formed. (From source 1) An asteroid is a rocky object in space that's smaller than a planet — they're sometimes called minor planets or planetoids, according to NASA. Other sources refer to them loosely as "space debris," or leftover fragments from the formation of the solar system. Asteroids have no atmosphere, but many are large enough to exert a gravitational pull — some have one or two companion moons, or they form binary systems, which is two similarly sized asteroids orbit each other. https://solarsystem.nasa.gov/deepimpact/images/Cratering_Diagram.jpg Meteorites are usually categorized as iron or stony, iron meteorites are composed of about 90% iron. Stony meteorites are made up of oxygen, iron, silicon, magnesium and other elements. (From source 2) Some meteoroids survive passage through Earth's atmosphere and hit the ground. These are called meteorites. (From source 3) How Impact Craters are Formed When an
What Is The Life Cycle of a Star?
TRIPLE SCIENCE Biology Ms. Xuereb Paulos Zerezghi 9AM What Is The Life Cycle of a Star? Stars are an astounding factor of our universe. To many, they are known to be ‘the lights of the universe’. They are much bigger than that. They even are born, they live and then they die. Stars are hot bodies of glowing gas that start their life in a big cloud of gas and dust known as a Nebula. This is the birthplace of stars as the gas and dust is what makes up a star. Our sun, i n fact was born in a nebula 5 billion years ago. Stars differ in mass, size and temperature, widths ranging from 450x smaller to over 1000x larger than that of the Sun. Space (where stars are) may seem empty, but actually it is filled with clouds of gas and dust. This gas and dust is known to be called interstellar medium. The gas atoms are mostly hydrogen (H2) and are not very spaced apart. The dust is mostly carbon and silicon. The stars that are blue have more heat are normally more scorching than the red stars which are less cool. The life span of a typical star covers millions of years that can even reach tens of billions of years. This means we can never fully observe the life of a star; from its birth to life to death. Our Sun is a perfect example of a star, and there is an

Mine, with the STS-135 mission seal, I bought from the Kennedy Space Center souvenir stand on Friday, a few hours before Atlantis took to the skies. I certainly won't need it to remember my first (and last) shuttle launch--something that's been thoroughly seared into my memory--but it will be a nice, frequent reminder of the incredible feelings of that day. It's been tough to articulate those feelings--where they came from, and why. But I think I've managed to trace them back to a single source: the four astronauts inside Atlantis. As of today,
