The Project: Taking emission spectra from red-shifted galaxies and converting the wavelengths of light into frequencies of sound, which can be played in audio software.

The Light Spectrum

Emission Spectra Variations in emission spectra can be due to: Elemental composition

Emission Spectra Variations in emission spectra can be due to: Elemental composition

Emission Spectra Variations in emission spectra can be due to: Elemental composition Ionization Dust and gas Star formation history Distance from Earth

Convert wavelength to frequency Lower the frequency range Producing Sound

Fourier transforms Red Shift Pink noise Producing Sound Sine oscillations

Looking Forward User friendly Web interface
