The Science and Technology Directorate at NASA's Marshall Space Flight Center sponsors the Science@NASA web sites. The mission of Science@NASA is to help the public understand how exciting NASA research is and to help NASA scientists fulfill their outreach responsibilities.
NASA's five THEMIS spacecraft have discovered a breach in Earth's magnetic field ten times larger than anything previously thought to exist. The size of the opening and the strange way it forms could overturn long-held ideas of space physics.
Solar flares are supposed to obliterate everything in their vicinity, yet one of the most powerful flares of the past 30 years has done just the opposite, emitting a beam of pure and unbroken hydrogen atoms. Researchers think this strange event could yield vital clues to the inner workings of solar flares.
From humble beginnings in a Utah beryllium mine to the most advanced laboratories in the world, the mirrors of NASA's next great observatory are taking an incredible journey to space.
This Friday's full Moon is the biggest full Moon of the year. It is a 'perigee Moon' as much as 14% bigger and 30% brighter than lesser full Moons we've seen earlier in 2008.
