Analyzing the spectrum of a star, or galaxy, can provide some useful information, including the temperature of a star, whether a star or galaxy is moving towards us or away from us, and the chemical composition.
Spectroscopy is still used today to identify the elements present in an unknown sample.
Spectroscopy allows one to study the interaction between radiation and matter as a function of wavelength (λ) and frequency (ν).
finding radiation by matter
no,it is reflection spectroscopy
Ultraviolet Electromagnetic Radiation
Mass spectrometry, UV/Vis spectroscopy, NMR spectroscopy CNMR spectroscopy, Infra red spectroscopy
Several variations of Raman spectroscopy have been developed.· Surface Enhanced Raman Spectroscopy (SERS)· Resonance Raman spectroscopy· Surface-Enhanced Resonance Raman Spectroscopy (SERRS)· Angle Resolved Raman Spectroscopy· Hyper Raman· Spontaneous Raman Spectroscopy (SRS)· Optical Tweezers Raman Spectroscopy (OTRS)· Stimulated Raman Spectroscopy· Spatially Offset Raman Spectroscopy (SORS)· Coherent anti-Stokes Raman spectroscopy (CARS)· Raman optical activity (ROA)· Transmission Raman· Inverse Raman spectroscopy.· Tip-Enhanced Raman Spectroscopy (TERS)· Surface plasmon polaritons enhanced Raman scattering (SPPERS)
Infrared spectroscopy cannot be used quantitatively. The sample preparation is also complex. It may be robust as the sample preparation may affect its results.
It can be used for element identification and can used in Atomic spectroscopy and can be used to help "atoms with low ionization potentials become ionized."
X-ray spectroscopy is used for detecting of breakable bone in body(2)it also for internal structures
The purpose of stellar spectroscopy is to determine the chemical composition of stars, the temperature and some other characteristcs..
The method is the spectrography.

Telescopes, spectroscopy, and a "Voyager" space probe.
Sodium chloride was used as crystal in infrared spectroscopy; but his hygroscopicity is a major disadvantage.
