Show Do Stars Explode? The appearance of a new star in the constellation of Perseus, and its rapid expansion into a nebula, which has been going on for some time past, have revived among astronomers the theory that some nebulae may be formed by explosion. About 1870 Prof. Eickerton of Canterbury college, New Zealand, showed that if two stars should graze one another the anraded parts, if relatively small, would have so high a temperature that they would at once become nebulous, and that the nebula so formed would under certain conditions, condi-tions, continue to expand until dissipated dissi-pated in space. The present expanding expand-ing nebula has been growing at the extraordinary rate of several thousand miles a second and is, in many ways, one of the greatest fielestial wonders of the time.
