The Sun’s outermost layer, the corona, is only visible to the naked eye during a total solar eclipse! Safe in the Summer Sun. Next Generation Science Standards: K-PS1 Energy. ... the sun. One way is to study the sun's spectrum — that is, break up its light with a prism. It is also the source, one way or another, of nearly all the energy we use on the earth. So if the amount of fusion decreased, then the energy from the sun would go down. Earth and Space: The cycle and patterns of the sun, moon, and stars can be observed.

We believe that is what the Milky Way looks like. The sun rises and sets every day. I think they are fairly shallow (not as deep as they are wide). The sun's surface temperature is about 5,800° Kelvin (about 10,000° Fahrenheit), and Betelgeuse is roughly half that, about 3,000° Kelvin (about 5,000° Fahrenheit).

If the sun became a supernova, the explosion would probably destroy the planets. No obligation or credit card is required. Toggle navigation. How large is the sun? Then how can the sun be burning? So our sun is kept in its path in our galaxy by the gravity of all those other stars. Daedalus (to himself ): Just a few more feathers, and we will be free. That is correct, because some of the light has been scattered away. Then it would get very cold and dark here! Alpha Centauri consists of two stars in orbit around each other. Earth (and we) are about 93,000,000 miles from the sun. How does the sun get its gases? Another way is to look at sunlight and measure how much light is in the blue part of the spectrum, in the yellow, in the red. The energy and light from the sun come from nuclear reactions deep inside the sun that occur at incredibly high temperatures millions of degrees! Not very close! First, let me assure you that the sun is not going to blow up any time soon! ... You are being redirecting to Scholastic's authentication page... GO BACK. Videos … This stream of charged particles can disrupt technology on Earth. But when a very massive star collapses, its gravity can be so great that it will compress its mass to a point — a black hole. On November 5, it’s expected to enter the sun’s atmosphere. The sun is, one way or another, the source of energy for all of us. Learn More . So it will run out of fuel some day — fortunately for us it won't be for a LOOOONG time. We know about them only from detailed mathematical models of the interior of the sun. Elementary science videos for every discipline from SuperScience magazine, using current events to engage your STEM classroom When the magnetic field is at its strongest, it pulls the sun inward. Weather patterns and seasonal changes can be observed and can affect daily activities. They give us our best "guess" of what is going on inside the sun. Always check with your parents before giving out information about yourself, entering a contest or sweepstakes, or buying anything online. It is composed mainly of hydrogen, with about 5%, by number of atoms, of helium and heavier elements. When the sun becomes a red giant, it will be a whole lot hotter in the solar system! The temperature is about 8,000 degrees Fahrenheit in the spot, and about 10,000 degrees at the surrounding surface of the sun! We think that a really big star, once it uses up all its nuclear fuel, will collapse and nothing can stop it. We can use the techniques I described above to measure their temperatures. We think that only really massive, big stars can become black holes. Some of the leftover gas and dust going in orbit around this baby sun became the planets. How big is the core of the sun?
