"Life and the Physical Universe" was the topic of Dr. Harlow Shapley's lecture at the Jefferson Physical Laboratory last night, where he gave the last of a series of talks on Cosmogony. His address dealt mainly with the question of the evolution of the stars. The evolution of the sun as one of the stars followed, and during this process came the birth of the planets of which the Earth is one.

The appearance of life on the Earth led to the question: is there life on other planets? Life can only exist under favorable circumstances and is dependent upon temperature, atmospheric conditions, oxygen, and water. Dr. Shapley pointed out that if life does exist on other planets in our solar system, it must be of a very different nature.
