Show Hottest of Stars Found by Science Shows 180,000 Degrees; Sun Cool by Contrast. Cambridge, Mass. An unnamed far-off star, whose surface temperature tempera-ture 19 180,000 degrees Fahrenheit, the highest heat ever measured i nywhere, was described to the con- arence on spectroscopy at the Massachusetts Institute of Tech-nology. Tech-nology. The sun's surface Is barely 10,000 degrees Fahrenheit The hottest temperatures previously reported, all on stars, were 35,000 to 40,000 degrees Fahrenheit A blue rainbow the distant star's ultra-violet light revealed the Inferno. This star Is a peculiar pe-culiar object It is a sun surrounded surround-ed by a nebula, which in the telescope tel-escope looks like a halo a star surrounded by something like the ring around the moon. Use New Instruments. It was this ring or nebula which made it possible to read the tem- i .1V. , I.O.i.mmt. cnA energy that they absorb and translate trans-late Into an extra glow "emission lines" in astronomical language. Calculations 9how that the source behind this hidden energy is ultra-violet rays streaming off the surface of the star. These driving rays are exceedingly energetic they are the radiations some astronomers as-tronomers have called the "death rays." They are so named because If the earth's atmosphere did not completely com-pletely screen them out they would be lethal to some small forms of. life. They might even give man a bad time. Though unseen, these rays are quite accurately calculated by the aid of the star tent It Is the calculation cal-culation of their energy which reveals re-veals the enormous heat of the star's surface. Doctor Bowen said that Mr. Zans-tra Zans-tra has observed what he thinks are still higher temperatures running run-ning up to 270,000 degrees Fahrenheit new methods. These were described by Dr. L S.
