University Research Most of us have, at some time in our life, looked up at llit stars and asked ourselves questions about them, but few of us have had the opjMirtunity of I)r. Willem .J. buyten, professor and chairman of astronomy, to study the stars through the new $8,000 microscope given to the I’niversity by the national Science foundation and to answer some of the questions which come to the mind of all of us. The new blink microscope will supplement the $$50 microscope buy ten has l een using since 10 23 to study glass photographic plates of the stars. Recently buy ten has been looking for blue stars up to 100,000 light years away, between the Milky Way ami the next galaxy. Blue stars have a temperature up to 100,000 degrees Fahrenheit. The sun in contrast is a yellow star of about 10.000 degrees, while red stars of about $.000 degrees won't show up at the great distances being studied. Motion of intergalactic Stars was studied with the older blink microscope through comparison of plates taken 80 years apart. Now the astronomy department's work is to locate further blue stars. DR. WILLEM J. LUYTEN, professor and choirmon of astronomy, studies photographic plates for the blink comparator which he is using in his motion survey. THE PLATES were made at observotories at the University of Arizona ond in Mexico. Twin Cities’ smoke, soot and haze, plus o lack of necessary telescopes and cameras, mokes it impossible for luyten to moke his own photographs. 23
