Stromatolites

Stromatolites are layered mounds or sheet-like layers of sedimentary rock that were originally forced by growing on a layer of cyanobacteria, a single-cell microbe. Fossilized stromatolites provide a record of ancient life and tidal patterns on Earth. Millions of years ago, seas all over the world would resemble the picture above, which was taken fromContinue reading “Stromatolites” Continue reading

HINS-Light > Purell?

Spectroscopy refers to the interactions between matter and light, or radiated energy, and the dispersion of an object’s light into its various wavelengths (i.e. colors). Dissecting an object’s light through spectroscopy helps modern astronomers determine the physical properties of stars. However, the study of light aids more than just astronomers in scientific battles today. New […] Continue reading
