Hydrogen is the most abundant element in the universe, making up 75% of matter by mass and over 90% by number of atoms. This element is found in great quantities in stars and gas giant planets. Lighter than air, hydrogen had been used as a lifting agent in balloons and airships. However, due to its risk of fire its use has been discontinued following the Hindenburg disaster in 1937. Hydrogen isotopes are used in the production of hydrogen bombs. In the solar wind, hydrogen’s plasma interacts with the earth’s magnetosphere giving rise to Birkeland currents and the aurora borealis.
