The magnitude of the magnetic field can be measured indirectly through the gyroresonance emission. Free electrons gyrate in the presence of a magnetic field due to the Lorenz force and emit radiation in the radio spectrum. This spectrum can be measured directly and used to calculate back the original magnetic field present in the solar gas.
 With increased density comes the high temperature, because the volume of the gas is decreasing. At some point, there is enough energy to produce a sustainable thermonuclear reaction and the energy dissipation counteracts with continuing collapse.
Binary stars are two stars that rotate around their common center of gravity. Through the observation, we can determine the period of rotation, i.e. time of one full turn of one start around another. This is enough information to calculate the stellar mass, therefore the answer is d.
Both measurements are designed to provide information about the brightness of a star. Apparent magnitude introduces a measure of how bright is a start when observed directly from Earth. Originally it concerned only the visible spectrum, but later the scale was increased to accommodate stars that emit mostly in invisible spectrum. Brighter stars have smaller apparent magnitude. An absolute magnitude is equal to the apparent magnitude of a star as if it were put 10 parsecs away from Earth. Therefore, the apparent magnitude depends on the distance to the star and the absolute magnitude does not.  ...Download file to see next pagesRead More

...might have ended up with a very different way of keeping track of time, and we most probably would have called it something other than a month” (Miles & Peters, 2001). The Christian celebration of Easter is calculated by determining the first Sunday following the first occurrence of a ‘full’ moon subsequent to the beginning of the Spring Equinox. The reason for this is that Christians had traditionally used the light of the ‘full’ moon to aid in their pilgrimage to their holy lands for Easter. Though the moon is the closest object to Earth and has been explored by man, questions remain regarding its exact origins and whether or not life ever existed on or within it or if it could sustain life. It was discovered more than...

General Questions for Marketing

...Marketing entails the 4 Ps and the C for in the middle. Describe in detail and use examples showing why companies must put more and moreemphasis on the customers. According to Dick Lee (n.d.), “putting the customer in the middle of the business circle” will determine the marketing orientation needed for the company, in order to exceed customers’ satisfaction (cited in Thompson, n.d.). International companies of today such as General Electric, Ford, and Procter & Gamble are becoming customer-oriented to have sustainable competitive advantage in terms of competition and long-term profitability. In other words, the customer is their boss and their superior. Therefore, a marketing orientation that covers all four directions...

...?Studying the Sun The Universe is a vast embodiment of unknown knowledge in which our tiny planet is apart of the giant picture, which makes individual humans insignificant in the grand scheme. However, humans are natural inquirers when it comes to the unknown. Civilization has come up with technology, which allows us to examine far and diverse celestial objects. Sometimes, however, observation cannot merely occur at just the visible level. Scientists are interested in the composition of these objects, especially stars due to the fact that nuclear fusion allows them to create denser elements in the core, which can serve as an indicator for how old the star is. One of these methods is through the use of spectroscopy. Spectroscopy... the Sun...

Johannas Kepler

...epistemology was profoundly concerned with astronomical practice, with methodological issues, and with the results of their application to the serious problems of late-renaissance astronomy. Kepler not only was able to ask questions in a way that no one had before asked, but he was able to provide answers to those questions that even now are worthy of continued study. From this perspective, Kepler was less the last great cosmologist of the classical tradition that includes Ptolemy and Copernicus; more was he the first cosmologist of the modern tradition. In the middle of the sixteenth century, fourteen centuries after the death of Ptolemy (c. A.D. 100-170), his Almagest still dominated...

...learned from this article, began some 4.6 billion years ago 'as rock and ice particles' revolving around the sun crashing and merging spawned into a bigger which generated huge terrestrial building blocks. These matters collided to form planets, including the Earth. Amidst this chaos, another matter the size of Mars, hit our planet with the force of 'trillions of atomic bombs', adequate to liquefy it in the end. The debris rapidly assembled itself into a sphere, and since then the history of the earth began. Moreover, I learned from this article that the earth began to cool with the formation of the moon as a natural satellite but the earth remained in an extreme condition for about 700 million years. Astronomers refer...

... Geological activities of earth Earth is geologically and biologically active because of two energy sources; one internal and one external. The internal energy source is earth’s molten core while the external energy source is the sun. Earth is the only planet which is having both geological and biological activities. “However, considering the fact that the solar system began as a cloud of gas and dust that was near absolute zero we might wonder where the earths internal heat came from to drive the plate tectonics.” (The Heat History of Earth) It is a confusing question for the scientific world to find out the relation between earths internal activities with solar energy. If earth’s internal activities are related to solar energy... Geological ...

.... Almost all of the students recognized evolution and The Big Bang Theory with their personal religion. God created the universe flawed, God created evolution to throw of unbelievers, and so forth were the main response. The American culture influenced how the students looked at science. Most children are taught about astronomy, biology, and other sciences, but religious beliefs take priority over facts. This is why Intelligent Design was introduced. Intelligent Design explains the science, but still does not refute God or higher power. Coincident or planned, the universe is a mystery. Everyday something new is discovered about space. This generation might have to face the fact that all of the universe’s...

...that continue to illuminate light in the universe. As a result many people all over the universe have been wondering what these stars, how far and their arrangement in the sky. These intimate questions have led to emergency of Astronomists who can help people try to understand what is happening in the universe. Unlike the ancient people who intimately familiarized themselves with night sky the modern people do not have that time thus the need for assistance from the specialists in sky matters. It is also important to note that the as the stay stars move in the sky they maintain the same pattern hence prompting the specialists come up with constellations. As far as astronomy is concerned there are...

The humans are made of carbon, they eat carbon and furthermore, the civilization is built on carbon. Carbon’s ability to form four bonds simultaneously means that it can be combined with itself and other elements to make a huge number of different molecules (Przyborski, 2013). 3.- What arguments could you make against sending messages via radio or spacecraft into interstellar Space?
