different pixels, ADU, zoom, and how to get the (x,y) coordinates. We then took this brief understanding of pictures and applied it to the stars. We loaded a picture of nebulae m42. After this we needed to calculate the average number of stars or solar masses. We found the (x,y) coordinates of a position in the center of the nebulae and on the edge of the nebulae. We used the following distance formula to find the distance between the points. After this calculation the answer in pixels needed to
Planets and Solar System "A planet is a celestial body that revolves around a central star and does not shine by its own light " (Grolier, 1992). The only planetary system that is known to man is our solar system. It is made up of nine planets which range in size and make-up. The nine major planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. There are also many other minor planets which are also in our solar system, but they are unimportant
The Solar and Heliospheric Observatory or SOHO for short is a cooperative joint effort by the European Space Agency (ESA) and the U. S. National Aeronautics and Space Administration (NASA). The main mission of this project is to study the internal structure of the Sun, its extensive upper atmosphere, as well as to determine the origin and characteristics of the solar wind. The SOHO spacecraft was launched on December 2, 1995 where then it was directed to go about 930,000 miles sunward from the Earth
The Solar System What are planets? Planets are kinda like asteroid around the sun. There are nine planets in the solar system, Mercury, Venus, Earth ( Our planet ), Mars, Jupiter, Saturn,Uranus, Neptune, and Pluto. The Terrestrial Planets The terrestrial planets are the four innermost planets in the solar system, Mercury, Venus, Earth and Mars. They are called terrestrial because they have a compact, rocky surface like the Earth's. The planets, Venus, Earth, and Mars have significant atmospheres
The Source, Nature, and Generation of the Graviton Field Summary The paper examines the possibility that atomic structures exists as complete self sustaining entities in identical form throughout the Universe, without any form of external input. The paper examines the energy budget of an atomic structure and concludes that gravitational attraction forms an inherent function of the structure in the form of low level quanta ejected from the structure as the final spent particle. It is postulated
in which the solar system and the universe as a whole was viewed began to change. With the controversial conclusions of Copernicus, scientists already began to adopt the idea of a heliocentric solar system. Further advancements in astronomy came about through the research of Tycho Brahe and his assistant Johannes Kepler. The three planetary laws developed by Kepler with the data gathered by Brahe shaped the way in which science viewed the structure and motion of the planets of the solar system in profound
History of Solar Energy Even though most people think solar energy is a recent invention, it has been around for centuries, even in ancient times. Efforts to design and construct devices for supplying renewable energy began 100 years before the height of the Industrial Revolution. Engineers and scientists worried about what would happen to the world’s nations after using up the fuel supply. Most of the environmental visionaries realized that the potential rewards of solar power outweighed
Solar cells Solar cells today are mostly made of silicon, one of the most common elements on Earth. The crystalline silicon solar cell was one of the first types to be developed and it is still the most common type in use today. They do not pollute the atmosphere and they leave behind no harmful waste products. Photovoltaic cells work effectively even in cloudy weather and unlike solar heaters, are more efficient at low temperatures. They do their job silently and there are no moving parts to wear
combustion. These two drawbacks in addition to the growing concern of global warming has pushed for the development of more sustainable sources of energy, namely solar energy and its derivatives (i.e. wind power). Solar energy is appealing for its potential to meet all our demands, while proving to be a pollution free resource.(Bohn, 2009) Solar energy originates from the thermonuclear fusion reactions occurring in the sun. Leaving all the byproducts of the reactions behind in the sun, the energy that
Gravity if one of the four fundamental forces in the universe. Though the fundamental principles of it eluded scientists until Sir Isaac Newton was able to mathematically describe it in 1687 (Eddington 93). Gravity plays a serious part in everyday actions as it keeps everything on the ground; without gravity everything would be immobile unless a force was applied (then it would move infinitely because there would be no force to stop it). Perhaps, the best place to start then would be with such
occurrences include sunspots, solar winds, coronal mass ejections, and solar flares. Sunspots are cool, dark-colored regions of the photosphere related to a shifting magnetic field inside the sun. However, sunspots are only dark in our perspective. A sunspot removed from the bright background of the Sun would glow brightly. Solar wind is the radiation of heat and a steady stream of charged particles. The wind blows about 450 kilometers a second throughout the solar system. Also, the Aurora Borealis
distinguish between mass and weight, one must know the basic definition of the two terms. Mass is typically defined as a measurement of how much matter in in an object or amount of inertia it holds. While weight is a measurement of how hard gravity pulls on the object. The mass always contains the same amount of matter however, the amount an objects weighs may fluctuate due to the gravity. The weight of an object depends on where it is, whereas mass always remains the same; mass does not change given
The Moon is the only natural satellite of Earth. The distance from Earth is about 384,400km with a diameter of 3476km and a mass of 7.35*1022kg. Through history it has had many names: Called Luna by the Romans, Selene and Artemis by the Greeks. And of course, has been known through prehistoric times. It is the second brightest object in the sky after the Sun. Due to its size and composition, the Moon is sometimes classified as a terrestrial "planet" along with Mercury, Venus, Earth and Mars. Origin
2.1 Principle A simple way for distillation water is a solar still which uses sun’s heat to derive evaporation from humid soil and atmospheric air to cool a condenser layer. The energy of sun heats water to evaporation point. When the water evaporates, vapours of water increases, condensing on the glass surface for collection. In a double slope solar still, solar radiation passes both sides of the glass cover. This energy coming from the sun is almost absorbed by the black
that planetesimals are small objects that are formed out of collided grains of dust and are stuck together to become larger objects. The first step in the formation of planets is that a protoplanetary disc was made from the materials of the solar nebula. The solar nebula was supposedly disc-shaped cloud of dust and gas left over from the formation of the sun. Because of this accretion, the smaller sized dust particles begin to gather together due to collisions which form larger bodies of planetesimals
Our solar system consists of eight planets, which can be separated into two categories. Those which reside inside the asteroid belt named the 'Inner Solar System' namely Mercury, Venus, Earth and Mars designated the terrestrial or rocky planets whilst those orbiting beyond the asteroid belt, Jupiter, Saturn, Uranus and Neptune classified as the 'Jovian Planets comprise the 'Outer Solar System'. The term Jovian is derived from Jupiter, which describes the remaining three planets as Jupiter-like.
2.4 Principles of Solar Cooker Naturally, earth has its own energy budget that hits the surface of earth and reflected back to the atmosphere. Figure 2.0.6 show the amount and percentage of earth’s energy budget. Figure 2.4.1: Earth’s Energy Budget In this project, we use three principles which are focusing sunlight to evacuated tube, converting light energy to heat energy and trapping heat energy. 1. Focusing sunlight to evacuated tube: A reflected surface with high specular reflectivity is utilized
happen. In the year 1929, Edwin Hubble made a revolutionary discovery. He learned that the universe is expanding. He saw that the galaxies were each moving away from us. Edwin knew that for one instance of time, almost 14 billion years ago, all of the mass of the universe was contained in a single spot. There had to have been a huge explosion that pushed all the matter away. This explosion is known as the Big Bang Theory. (www.science.nasa.gov) NASA is now monitoring the expansion of the universe in
Background Information Solar chargers use solar energy from the sun to supply electricity to charge devices or batteries. A lot of research has gone into the area of solar charging in recent years and there are many types of solar powered chargers readily available on the market today. Some examples of types of solar chargers include: • Small portable chargers which are designed to charge a variety of mobile phones, tablets or other portable audio equipment. • There are fold out solar chargers available
colonize the planets of other stars, and spread throughout the farthest reaches of the galaxy. However, we can’t just go out and start colonizing the galaxy overnight. First off, we need to take relative “baby-steps” and colonize another planet in our Solar System. The best candidate for this; Mars. Mars is the best candidate because it has water ice on its surface, it’s not as hot as Venus or Mercury, it has an atmosphere to shield from asteroid impacts, and its days are nearly as long as Earth’s. There
