Say what? Helium is pronounced as HEE-lee-em. Helium, the second most abundant element in the universe, was discovered on the sun before it was found on the earth. Pierre-Jules-CÃ©sar Janssen, a French astronomer, noticed a yellow line in the sun's spectrum while studying a total solar eclipse in 1868.
After hydrogen, helium is the second most abundant element in the universe. It is present in all stars. It was, and is still being, formed from alpha-particle decay of radioactive elements in the Earth. Some of the helium formed escapes into the atmosphere, which contains about 5 parts per million by volume.elium is the second most abundant element in the universe, but here on earth, it's rather rare. Most people guess that we extract helium from the air, but actually we dig it out of the ground.
