The ET (External Tank) is the largest element of the space shuttle, and when loaded, it is also the heaviest. It consists of three major components: the forward liquid oxygen (LOX) tank an unpressurized intertank that contains most of the electrical components the aft liquid hydrogen (LH2) tank; this is the largest part, but it is relatively light, due to hydrogen's very low density. Those 2 chemicals funnel out of the engine and when combined energy is released.
How massive can a star be? Estimates made from distance, brightness and standard solar models had given one star in the open cluster Pismis 24 over 200 times the mass of our Sun, making it a record holder. This star is the brightest object located just to the right of the gas front in the above image. Close inspection of images taken recently with the Hubble Space Telescope, however, have shown that Pismis 24-1 derives its brilliant luminosity not from a single star but from three at least.
Where can educators (including homeschoolers) get free math and science teaching materials? Where can they attend training workshops? And where can they get hands-on demonstrations to illustrate classroom activities? NASA's Educator Resource Centers, which are located around the country.
