Chandra's Previous Numbers Game Results - 2005Question 16: Some of the X-rays detected by Chandra from supernova remnants are produced by electrons spiraling in magnetic fields. These electrons have energies of 10 trillion electron volts more. How does this energy compare to the maximum energy produced by electron accelerators on Earth? (September 15 - November 2, 2005)Question 15: The X-rays from Saturn s rings are primarily due to fluorescence following absorption of solar X-rays by water ice in the rings. About what thickness of ice does it take to absorb the solar X-rays? (June 28 - September 15, 2005) Question 14: The diameter of the pulsating red giant star Mira varies from about 200 to 400 times the diameter of the Sun. If such a star were located at the position of the Sun, how far out in the solar system would it extend at maximum diameter? (May 2 - June 28, 2005) Question 13: A typical aurora on Jupiter has a peak power of about 30 trillion watts. How does this compare to the total peak power output of all the electricity generators in the U.S.? (March 2 - May 2, 2005) Question 12: Approximately how many stars form each year in the Milky Way Galaxy in the current era? (January 26 - March 2, 2005) |
