All Jewish holidays begin at sundown because the Jewish people believe that the day begins in the evening and ends the next evening. Yom Kippur begins at sundown on the day before the date specified on the Jewish calendar for the holiday and ends an hour after sunset on the specified date. Fasting and prayer lasts for the entire 25-hour period, and observers often spend much of the time in the synagogue.
Yom Kippur, or the Day of Atonement, is the holiest day of the year for the Jewish people. It's a very culturally significant holiday, and even secular Jews often attend synagogue on Yom Kippur. The holiday is always celebrated on the tenth day of the seventh month, which on the Jewish calendar is Tishri. This month falls between September and October. The dates of Jewish holidays differ every year because the Jewish calendar is not strictly a lunar calendar. The Jewish calendar compensates for changes in the lunar cycle by adding a month when necessary.Learn more about Our Sun

The sun's radiation interacts with Earth's atmosphere and lifeforms to act as the main source of energy. Solar radiation travels in straight waves. Earth's axis is usually angled to let this energy into its atmosphere so that it can reflect from the surface; if the sun's energy is unable to reach Earth because of its orbit, then ice ages occur.Full Answer >
The sun formed from a collection of gas and dust that pulled together by mass gravitation; the extreme pressure caused by this great mass produced a nuclear fission reaction that fueled the sun and continues to keeps it burning. The primary elements that make up the sun are hydrogen and helium. Scientists theorize that the shock wave from a large supernova drew together the dust particles that became the sun.Full Answer >
The sun's energy comes from thermonuclear fusion reactions. Because the sun's gravity is so strong, hydrogen atoms fuse together to form helium. When they do so, they release a tremendous amount of energy.Full Answer >
