Author defends doctrine of plurality of inhabited worlds by citing current astro- r.or; ical discoveries and by analyzing and refuting objections. Briggs, Michael H. Other astronomers in the universe? Southern str.rs, v. 18, Sept. 1960: 147-151. Author con:dder~ problems raised by the hypothesis that some cosmic radio signals :i.re im.ellige1~tly produced. ----- Superior galactic communities. Spaceflight, v. 3, May l!l61: 109-110. Author suggests that if there are intelligent extraterrestrials on pl&.nets in this galaxy, they may be sc:entifically and technolof!:ically advanced enough to know of both earth and of man as ari intelligent life form. Attempt by them to es- tablish contact might be by radio transmissions, space probes, and emission of radiation in the far infrared. ----- Terrestrial and extraterrestdal life. Spaceflight, v. 2, Oct. 1959: 120-121. Hypothesis for origin of life on earth is given based on three assumptions: (1) intelligent life existed somewhere in t' , universe prior to the beginning of life on earth; (2) interplanetary flight is possible by these inte::lligences; and (3) life- less earth was visited by extraterrestrials who either deliberately and accident- ally left microbes behind when they departed. Variations oI and objections to hypothesis are given. Cade, C. Maxwell. Are we alone in space'i Discovery, v. 24.
