Energy Star

interferometers. Discuss major discoveries that were possible after detection of radio waves from space and how they changed our understanding of Universe. Astronomy is all about increasing our understandings about our Universe through observing objects like stars, galaxies and other bodies which exist outside Earth’s atmosphere. Astronomers make observations of these celestial phenomena by collecting electromagnetic radiation. Optical telescopes e.g. the Hubble Space Telescope collect light…

today. Those two things are hydrogen and helium. The temperature it normally stays at is around 15 million degrees celsius. Which is enough heat to reach to are planet earth this day. The sun tends to be a bomb with this much material packed into one star. But yet gravity keeps it together. As time goes the earth will be consumed by the sun. The sun grows bigger and bigger every year. Which will eventually expand to a certain point then earth wouldn't exist.…

Energy performance of the original house is not terribly bad but not satisfied, either. It wastes a huge amount of energy in cooling the living area. Strategies of achieving better passive heating and cooling will be illustrated as following. Reducing cooling energy consumption will be emphasized in designing the new house. The original orientation (315 degrees with living room faces south-west) resulted in excessive heat gain during summer, especially in the afternoon, and insufficient heat…

The Sun and Our Star - Have you ever questioned as to how and why we are able to dry our clothes in the summer, and to be able to heat food and treat our water? - This all thanks to the sun - Without the sun, we all would be dead, it gives us light, heat and energy to heat up the Earth - Most of the energy stays inside of the sun because of its gravitational pull, and all small amounts leave the surface in the form of radiant energy Type of star: Age: Yellow dwarf 4.5 Billion Years…

It is easy to find this constellation because within it are seven very bright stars that make up what we call “The Big Dipper”. The Big Dipper has also been used for navigational purposes for hundreds of years. The reason is, if you line up the two stars that form the back the cup of the dipper and go straight up about 5 times that distance you will see Polaris, a bright star in the Ursa Minor Constellation, and that star is right on top of the north pole. Another interesting body to see in the…

few however, will be able to tell you where these forms of radiation come from. The answer: Pulsars. Pulsars, or neutron stars, are physics sandboxes that provide extreme conditions for humans to experiment with which are not readily available on Earth. Due to this usefulness, the discovery and research of these phenomena should be of the utmost importance. These neutron stars, barely 12 miles across, are troves of undiscovered scientific mysteries. To begin our journey into the mysteries of…

we spend during long space travel, stay in the cold, vacuum universe would let astronauts experience different kind of radiation. These radiation may be some ionized particles as electromagnetic waves traveling with high speed and energy. They could come from nearby stars or even from those that are light-years away. Some of them has higher permeability when they are transmitting in the vacuum. Astronauts’ over exposure to the radiation during the long-term space travel can cause unfavorable…

Energy is the dynamic force that helps with everyday biological functions (Brewer, 2013). The energy that is received throughout the day is affected by the foods consumed such as sugars,carbs, proteins, and other foods ranked on the Glycemic Index. The glycemic index (gi) rates food on a scale of how quickly glucose is released into the body (Brand-MIller, 2014). Foods high on the gi quickly release glucose into the body, while foods low on the gi slowly release sugars over time. When glucose…

different forms of energy and work. Not only does the thermodynamic state define volume, temperate and pressure, it will contain heat sources giving a capacity, and change state. The idea of thermodynamics is for the system to adjust itself back into its original state of an equilibrium. Through expressing the laws of thermodynamics, it is apparent that heat energy is important in the world in order to achieve ultimate equilibrium. When given a system, it is states that energy cannot be created…

environmentally friendly energy is needed sooner rather than later (The Guardian). Fusion energy will be a future energy source, with the ITER machine under construction based on the ‘Tokamak’ concept of magnetic confinement. ITER is predicted to start operating in 2019, with electricity generation to follow thirty-forty years later (ITER). In a fusion reaction, energy is released when two light atomic nuclei are fused together to form one heavier atom. This process powers the Sun and stars…
