Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. It is light, diuses rapidly, and burns. Helium is the second most abundant element in the universe, after hydrogen, and is a major constituent of the gas-giant planets in our Solar System. 10 How are hydrogen and helium responsible for life here on Earth? Traces of hydrogen, helium, and potassium were also detected. During formation, the Earth was is not sufficiently massive to retain free hydrogen (or even helium, the next lightest) because these gases are so lightweight, so instead of being 98% hydrogen and helium like the universe overall, the earth started out with zero free hydrogen and helium, as both floated off into space. Unconstrained by such devices, the light gases Over time, Earths oxygen levels have changed significantly with varying levels of hydrogen, helium, carbon dioxide, nitrogen, and oxygen. On Earth, hydrogen mostly exists in molecules such as those of water, minerals in the earth and organic compounds.

NASA Begins Assembly of Europa Clipper Spacecraft. Stellar nucleosynthesis has occurred since the original creation of hydrogen, helium and lithium during the Big Bang.As a predictive theory, it yields accurate estimates of the observed abundances of the elements.It explains why the observed Hydrogen atoms are just protons. The ratio of helium to hydrogen was determined from the refraction (bending) of Voyager 2s radio signal by the atmosphere as the spacecraft passed behind the planet. Under low pressure, particles of hydrogen and helium, called molecules, have lots of room to bounce around. Winds in the upper atmosphere can reach speeds of 500 metres a second, these combined with heat rising from within the planets interior cause yellow and gold bands. A 0.5 Earth-mass planet, of Earth composition, would have a radius of (0.5)^0.3 ~ 0.81 times Earth and thus a surface gravity of (0.5)^0.4 ~ 0.76 times Earth, with a column mass of ~1,350 tonnes, of which 75% is hydrogen.
