Helium is a nonrenewable colorless and odorless gas that is typically recovered in natural gas deposits, like the ones found in Lincoln County, Wyoming. Helium is the most stable element and will not burn or react with others, which is why it is used as a safe gas for filling balloons. It has the lowest melting and boiling points of all elements on the periodic table. At -452 degrees Fahrenheit helium changes from a gas to a fluid. Helium’s uses go far beyond birthday parties. Its inert properties make it popular in various fields, from medicine to space exploration. In healthcare, helium is used in diagnostic tools like MRI machines and surgical lasers. The defense industry uses it for rocket engine testing, surveillance drones, missile guidance, and thermographic cameras. Manufacturers test products such as aerosols for leaks using helium. In nuclear energy, helium serves as a cooling agent in certain reactors. NASA employs helium to separate hot gases from ultra-cool liquid fuel during launch sequences.
