A Test for the Detection of Vegetation on Extrasolar Planets: Detection of Vegetation in Earthshine Spectrum
International audience The search for life in extrasolar planets is to be tested first with the only planet known to shelter life. If the planet Earth is used as an example to search for a signature of life, the vegetation is one of its possible detectable signature, using the Vegetation Red Edge du...
