Title:
Southern Lights and Shuttle Glow
Explanation:
A background of distant stars, sinuous and spiky bands of Southern Lights (Aurora Australis) [ http://antwrp.gsfc.…], and the faint glow of charged plasma (ionized atomic gas [ http://www-spof.gsf…]) surrounding the Space Shuttle Discovery's engines [ http://antwrp.gsfc.…] give this photo from the STS-39 mission an eerie, otherworldly look. This image [ http://images.jsc.n…] reflects Discovery's April 1991 mission well - its payload bay (PLB) was filled with instruments designed [ http://images.jsc.n…] to study celestial objects, aurora and atmospheric phenomena, and the low Earth orbit environment around the PLB itself. The aurora [ http://www.geo.mtu.…] seen here are at a height of about 50-80 miles. Aurora are caused by charged particles in the solar wind [ http://www-spof.gsf…], channeled through the Earth's magnetic field [ http://www-spof.gsf…] which excite molecules in the upper atmosphere.
