HOT GAS --- "A Way Cool Subject"

• NASA launched the “Cosmic Hot Interstellar Plasma Spectrometer” (CHIPS) satellite, developed at UC Berkeley, to carry out observations of extreme UV spectral line emission from the interstellar gas (300,000 K - 1 million K)
   
• CHIPS performs spectral observations at EUV wavelengths (90 - 260 Å) of diffuse emission from hot plasma in the “Local Bubble”

• Spectral resolution must distinguish primary cooling lines, separated by approx. λ/50
