On This Day August 18

French astronomer Pierre Jules César Janssen discovered helium on August 18, 1868, while analyzing the chromosphere of the sun during a total solar eclipse in Guntur, India. Because helium was found in the Sun before it was found on Earth, its name comes from the Greek word for Sun, helios. Helium is the only element that was discovered in space before found on Earth.
