Helium discovery
Working in Bailey Hall on December 7, 1905, Hamilton P. Cady and David F. McFarland discovered significant amounts of helium in a natural gas sample from Dexter, Kansas. Cady and McFarland subsequently analyzed more than 40 other gas samples, showing that helium, previously thought to be rare on Earth but abundant in the Sun, was available in ...The discovery of helium's existence preceded its discovery as an element on Earth. In 1868 Pierre J. C. Janssen travelled to India to study a total eclipse and he observed a new line in the corona spectrum, which meant an unknown element was present on the sun. (He named it helium thinking it would be a metal.)The discovery sheds new light on the deepest and most mysterious region of our planet, and hints that helium-3 from the core might escape upward through the …
