Relating to the analysis of light spectra from stars and celestial objects to determine their composition, temperature, and motion.
From astro- (star) combined with spectral (relating to spectra). Emerged in the 19th century when astronomers began using spectroscopy to analyze starlight.
Astrospectral analysis revealed that the same elements found in Earth's rocks and metals are scattered throughout the universe—proving we're literally made of stardust and share chemistry with distant galaxies.
