Quasars give off nearly 1,000 times the amount of energy that the Milky Way emits. These quasars emit so much energy that astronomers speculate that the most probable power source for a quasar is a supermassive black hole, according to Sloan Digital Sky Survey.
The supermassive black hole that sits at the center of a quasar is surrounded by a rotating ring of gas. This mass of gas then falls into the black hole and is heated to millions of degrees. The heated gas then emits very powerful thermal radiation that spans the visual spectrum. According to Sloan Digital Sky Survey, quasars are the brightest objects in the universe. The closest quasar to Earth is around 800 million light-years away. Because of this, it is possible to assume that the last quasar died out 800 million years ago.Learn More
Bananas are considered to be a good source of energy and are prized by recreational and endurance athletes alike. Due to bananas being a good source of potassium, minerals, vitamins and other nutrients, along with their portability, bananas are popular with cyclists, hikers and other athletes, according to researchers at Appalachian State University's Human Performance Lab.Full Answer >
Heat, light, sound and electric energy are all forms produced in a lightning strike. The bottoms of clouds typically become negatively charged, while the earth beneath them becomes positively charged. When the potential difference between the two becomes sufficient to break down the electrical resistance of air, lightning strikes occur.Full Answer >
The sun gives off solar energy. The sun is a star that is a furnace in which hydrogen nuclei undergo fusion to produce helium along with rarer and heavier elements.Full Answer >
While most energy comes from the carbohydrates an individual consumes, a body can't use that energy unless it has plenty of protein, Fitday indicates. So protein's role is more of a supporting one; protein doesn't directly provide a body with energy.Full Answer >
