A possible key to the mysteries of intergalactic space lies in the recent discovery of a globular cluster, a unified system containing tens of thousands of stars, at problaby an enormous distance from the Milky Way plane.
This cluster may be one of the exceedingly few objects known to lie between the galaxies. It is located six degrees from the South Pole of the sky in the constellation of Menss.
The life of planetary nebulae has been found by Fred L. Whipple, instructor in Astronomy, to be, on the average, about 30,000 years. These bright bodies with their large and rapidly expanding gaseous envelopes, develop in the manner of exceptionally slow novae.
