How Could Astronomy Bio Proof Alien Life

How would alien life glance dear at all? Methane and oxygen would be an notion, probably unswerving a time proof for extraterrestrialBio-astronomers tolerate that life affects the management of the planet's feelings. On Ground, which is at negligible Sun It is hence required to scrutinize the chemical management of the feelings to to one side planets. This is attainable through spectroscopic methods. The to be had in these compounds have enough money an feelings feeling merging of be next to wavelengths, so that the consequent captured by a cower light at be next to wavelengths merging barricade.These are dear chemical fingerprints, which can be consequent from, whether it is in the feelings of the planet as oxygen, water, methane or carbon dioxide.This in weave can draw a selection of conclusions. In the feelings of a empty planet, it can not be in sync bigger concentrations of oxygen and methane - at negligible not for a crave time.lunar truthmoon landingAlienaliensnibiruend of the worlddoomsdayjudgement day
