Spectral Signature of Life • Particularly, spectroscopic observation is a powerful tool to investigate the chemical composition of exoplanets. • Not only on Earth but also in the interstellar space, carbon exists abundantly in several oxidized (e.g., CO2) and reduced (e.g., CH4), forms. This allows ...

This method is most likely to find large planets close to their stars, however. Transits are better suited to finding something more like Earth in size and orbit. So far, 5 ...
