Gupta explained that hydrogen atoms may eventually transform into molecular gas, the basic fuel for the formation of stars.

For rapid diagnosis, particular spectral wavelengths of interest can be investigated ... and spectral imaging over a conveyor processing line, hyperspectral sensors introduce new inspection ...

Each library spectrum was formed by combining data from several sources overlapping in wavelength coverage. The SIMBAD database, measured colors, and line strengths were used to check that each input ...

Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When a gas is very hot, it doesn’t emit all wavelengths of light.
