Drake, W. Raymond. Is our sun inhabited? Flying saucer review, v. 5,
Nov. -Dec. 1959: 15-17.
Author summarizes theori~s on the nature of the sun and speculates that the
heat and light reaching earth from it might be provided by methods other than
nuclear explosion on the sun itself. Habitability would then be within the
realm oi possibility.

Discussion of the thel)ry that there was once a planet in our solar system between

might represent fragments of this exploded planet, author speculates.

In astronomy, the author says, we are faced by contradictions. Not all the
apparent data of the moment can be correct; we do not know which fragments
are right and which are wrong~ Because we cannot experiment with the
universe, we live in a kind of shifting uncertainty, shifting because as the
years pass the balance of certainty of a given piece cf data changes,
Huang, Su-Shu. The sizes of habitable planeh;. Publications of the Astronomical
Society of the Pacific, v. 72, Dec. 1960: 489-493,
Conditions necessary for a habitable planet are reviewed. It is tentatively
concluded that a habitable planet most likely will have a radius lying between
1, 000 and 20, 000 km. It is also suggested that the rate of biological
evolution on a planet may increase with its surface area if other conditions
are equal.
