The Electrical Measurement of Starlight

Nature volume 52, pages 246248 | Download Citation



THAT the light of a star is able to produce at the surface of the earth a measurable effect, other than the action on a photographic plate, is a fact which was published in these pages in January last year. The light of stars and planets produces two effects—the one photographic and the other electric. The first—which has, of course, been known for many years—is slow in its operation; the second—which was discovered only a year ago in Mr. Wilson's observatory at Daramona, Westmeath—is almost instantaneous.
