<h3>What do galaxies look like at different wavelengths and what can we learn from this?</h3>

<p align="justify">Evolution of galaxies is imprinted in their spectrophotometric properties. Strong starburst events or periods of quiescent star formation that took place during lifetime of a galaxy result in consequent generations of stars which we can observe now. The contributions of different types of stars to fluxes at different wavelengths vary a lot. In certain spectral regions, there may also be a contribution from the emission of the gas and dust in the interstellar medium. In some galaxies, nuclei possess different levels activity creating specific features in their spectra.</p>

<p align="justify">Our project will shed the light on galaxy formation and evolution from the studies of their spectrophotometric properties at different wavelength. We compile a sample of hundreds of thousands of galaxies using only publicly available data from archives, databases, and resources of the International <a href="http://ivoa.net/">Virtual Observatory</a>.</p>

<p align="justify">These web-pages will be updated regularly. The first release of our galaxy catalogue containing ultraviolet-to-infrared spectral energy distributions complemented with the results of the analysis of their optical spectra available from the <a href="http://www.sdss.org/">Sloan Digital Sky Survey</a> is planned for April 2016.</p>

<p align="justify">At this stage, we provide the first scientific result of our study emerged at the catalogue construction phase, <a href="relations/">a universal ultraviolet-optical colour-colour-magntude relation</a> of non-active galaxies.</p>
