Like gems hidden in mountains of sand, I have sifted through vast amounts of data which have been gathered by surveys covering wide areas of the sky at particular wavelengths, and found likely star forming cores, hints of circumstellar disk and outflows in regions of massive star formation. The procedural lesson from my masters thesis is that there are discoveries waiting to be made by comparing data sets gathered at different frequencies, and by conducting coordinated multi-spectral surveys of massive star forming regions.
