Adapted to their very hot but watery environment, these microbes metabolized hydrogen - rich compounds or dead or live organic materials to derive the energy that sustains anaerobic life, including sulfate - reducing bacteria that produce Hydrogen Sulfide (H2S), fermentative bacteria that produce carbon dioxide and alcohol -LRB-- OH), and methanogenic bacteria — the methanogens found in sewage and mudflats today — that produce methane (CH4) gas as a waste hydrogen - rich compounds or dead or live organic materials to derive the energy that sustains anaerobic life, including sulfate - reducing bacteria that produce Hydrogen Sulfide (H2S), fermentative bacteria that produce carbon dioxide and alcohol -LRB-- OH), and methanogenic bacteria — the methanogens found in sewage and mudflats today — that produce methane (CH4) gas as a waste Hydrogen Sulfide (H2S), fermentative bacteria that produce carbon dioxide and alcohol -LRB-- OH), and methanogenic bacteria — the methanogens found in sewage and mudflats today — that produce methane (CH4) gas as a waste product.

The team went back to the drawing board and eventually realized that the 100 - MHz estimate was based on the assumption that the hydrogen gas was hotter than everything else around it.

The cold hydrogen gas map was superimposed on a map of the cluster's hot gas, which was generated using observations from NASA's Chandra X-ray Observatory.

When the star's ultraviolet radiation strikes the gases in the nebula, they heat up, giving out radiation ranging in wavelength from blue — emitted by hot oxygen in the bubble near the star — to yellow — emitted by hot hydrogen and nitrogen.

They routinely create hot plasma jets and gas bubbles that are thought to prevent the cooling of galaxies and regulate the formation of stars, which requires cold hydrogen gas as a building block.

Eventually the hydrogen gas gets dense and hot enough for nuclear reactions to start.

Fusion energy is based on the same process that takes place in the sun, where gravity holds together the hot ionized gas called a plasma and nuclei of hydrogen collide together often enough that they occasionally overcome forces keeping them apart, called the Coulomb forces, to fuse together and create a burst of energy, Synakowski explained.

Theoretical modelling indicate that a hot steam planet could form if it formed in a colder orbit farther from GJ 1214, where lower temperatures would have created an ice - rock composition similar to Jupiter's moon Ganymede, and the planet should have formed too late to accrete a large hydrogen - helium gas envelope.

Stars are massive, glowing balls of hot gases, mostly hydrogen and helium.
