Helium can be found in underground deposits in the earth. Helium can also be found in stars and other planets. The helium underground - and extracted from natural-gas - is a by-product of the natural radioactive decay of uranium, though is far too stable to be radioactive itself. It also occurs in very small amounts in the atmosphere.
Even when first discovered and identified, scientists knew there were large amounts of helium in the Sun. Similar to hydrogen (H), helium is usually found as a gas and has no color or smell. Helium is found everywhere in the Universe and is the second most common element, just behind hydrogen. As far as we're concerned, helium is a happy element.
