NIST ultraviolet source helps NASA spacecraft measure the origins of space weather
With a brilliant, finely tuned spark of ultraviolet (UV) light, a physicist at the National Institute of Standards and Technology (NIST) helped NASA scientists successfully position a crucial UV sensor inside a space-borne instrument to observe a "hidden" layer of the Sun where violent space weather can originate.Dark spots on the Sun release particles and electromagnetic fields into space. As these particles and fields pass through the Sun's "transition region," 5,000 kilometers above the surface, they can gather considerable steam, resulting in violent episodes of "space weather" that can damage Earth-orbiting satellites and disrupt electronic communications.The powerful magnetic fields in the transition region can be studied indirectly, by observing the UV light emanating from that region. The fields slightly shift the colors (wavelengths) of UV light released by charged atoms (ions) in their vicinity. Measuring how much these wavelengths shift can yield information on the mag
