extraterrestrial

Finding life outside the planet Earth several is the ultimate goal of an astrobiologist. Using known astronomical measurements and assumptions the probability of extraterrestrial life existence could be estimated. Equations such as the Drake equation (1961) as stated in the paper of Molina (2019) doi:10.48550/arXiv.1912.01783, Seager (2013) https://www.space.com/22648-drake-equation-alien-life-seager.html and Foucher et al, (2017) doi:10.3390/life7040040 are included in the 'extraterrestrial' package.
