   Apr 22, 2024 · While the chances of finding life elsewhere remain unknown, the odds can be said to be improving. A well-known list of the data needed to determine the likely abundance of life-bearing worlds, though highly conjectural, is known as the “Drake equation.”. Put forward in 1961 by astronomer Frank Drake, the list remains mostly blank.
