Observatory of the Carnegie Institution have established that Mira, the remarkable variable star dis-Jeovered by David Fabricius in 1596, in the constellation Cetus, is the second largest known star, thereby displacing the noted Betelgeuse for that honour. With an angular diameter of about 250,000,000 miles, it is exceeded only by Antares, the chief star of the constellation Scorpio, with a diameter of 400,- 000,000" miles. is larger It shout 25. per cent, than Betelgeuse fir the constellatic yn, which was measured for the first time about four years ago.
Appearing as but a speck in the! sky to the naked eye, the measure ments of Mira were made by. Dr. Francis G. Pease with the 20-foot Michelson interferometer attached te the observatory's 100-inch tele scope, the same with which the first measurements of Betelgeuse were obtained.
Apnouncement of the measure. ment. was made to-day by th Carnegie Institution, on the basis of advices from Mr. Wilson, "The results indicate," the announcement says, "an angular diameter for 8t Mira of about six-hundredths of a second of are, cent. larger than Betelgeuse. most probable value of the distance ig 165 light years mining this Jaistance, the diameter of the star sistance proposed by the League of, Nations, on the ground that the:
