Discussion on Calculating the Sun’s Energy
The sun is the closest stellar object to our planet, a main sequence star (G-2, yellow dwarf). It has long served as a source of inspiration for mankind throughout civilization as the primary source of light and heat; life as we know it would not exist without the sun’s energy. Students will be able to describe the fusion reactions that are necessary for the sun’s existence, measure the sun’s energy output, and compare the sun’s energy to traditional fossil-fuel resources on Earth after completing this course.
Solar wind, helium, hydrogen, fusion, core, sunspot, plasma, solar eclipse, and radiation are some of the terms used in this paper.
Students should be able to: Describe how the sun was formed, as well as its present stage of stellar evolution, after completing this course.
Recognize solar features such as sun spots, solar flares, and eclipses.
Quantify the sun’s energy production and compare/contrast it to other forms of energy utilised on Earth.
Motivation / Introduction
Our solar system revolves around the Sun, which is a G2 main sequence star. The Sun is at least 4.5 billion years old and comprises about 99 percent of all the mass in our solar system; a million Earths might fit inside it! The Sun is an active star with its own atmosphere covered with denser gasses at its core, with a diameter of over 1.39 x 106 km and a mass of 1.99 x 1030 kg (330,00 Earths!). The photosphere is the part of the sun that emits visible light, allowing humans to view the radiant energy despite the fact that it is hidden beneath two more layers of the atmosphere. The chromosphere is seen beyond the photosphere only when the photosphere is obstructed, such as during a solar eclipse. Filters can also be used to photograph the choromosphere. The corona is the Sun’s outermost zone, which stretches millions of kilometers beyond the photosphere. Though the corona frequently appears beautifully during a solar eclipse, the visible light observed in it is only a fraction of what is emitted from the photosphere (see figure 22.2). It appears as spicules in the shape of a starburst that shoot out in all directions from the Sun. Some of this energy can escape the Sun’s atmosphere and flow into space as solar wind, which is made up of protons and electrons.
During the total solar eclipse of 1998 in Antigua, West Indies, the Sun’s corona can be seen. The “diamond ring” effect occurs just seconds before totality and is known as “the diamond ring effect.” Kelly Knight is the photographer for this image.
Light-years (ly) or the astronomical unit (AU) are used to measure distances (astronomical unit: the distance from the Earth to the Sun). BTUs and kilowatt-hours are examples of energy units.

The electromagnetic (EM) radiation (EMR) released by objects includes visible light. Dangerous cosmic rays, X-rays, radio waves, infrared, and ultra-violet radiation are among the wavelengths emitted. The visible spectrum of EMR is only a small fraction of the total spectrum. Processes like hydrogen fusiona thermonuclear reactioncreate EM radiation for our sun. Gasses in nebulae are heated to the point that they incandesce (glow) in the same way that a fluorescent light bulb does. EM radiation from neighboring stars or heat generated by compression of these same gasses could be the sources of heat for luminous nebulas.
QUALITY OF RESPONSE NO RESPONSE POOR / UNSATISFACTORY SATISFACTORY GOOD EXCELLENT Content (worth a maximum of 50% of the total points) Zero points: Student failed to submit the final paper. 20 points out of 50: The essay illustrates poor understanding of the relevant material by failing to address or incorrectly addressing the relevant content; failing to identify or inaccurately explaining/defining key concepts/ideas; ignoring or incorrectly explaining key points/claims and the reasoning behind them; and/or incorrectly or inappropriately using terminology; and elements of the response are lacking. 30 points out of 50: The essay illustrates a rudimentary understanding of the relevant material by mentioning but not full explaining the relevant content; identifying some of the key concepts/ideas though failing to fully or accurately explain many of them; using terminology, though sometimes inaccurately or inappropriately; and/or incorporating some key claims/points but failing to explain the reasoning behind them or doing so inaccurately.
