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.
Helium deposits in the earth's crust are thought to have been created by radioctive decay of elements like uranium and thorium. But the largest naturally occuring source of helium is found in natural gas.elium (and the other noble gases that are normally chemically unreactive) are found in volcanic gas emissions. But unless it is really, really large you're not going to be mining it for helium; there just wouldn't be enough to collect there to make it worthwhile.
