A hydrothermal vent is a fissure in a planet's surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Common land types include hot springs, fumaroles and geysers. Under the sea, hydrothermal vents may form features called black smokers. Relative to the majority of the deep sea, the areas around submarine hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic bacteria and archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp. Active hydrothermal vents are believed to exist on Jupiter's moon Europa, and Saturn's moon Enceladus, and ancient hydrothermal vents have been speculated to exist on Mars.
The chemical precursors of present-day biomolecules could have formed not only in the deep sea at hydrothermal vents, but also in warm ponds on the Earth's surface... They even found that one of the nucleobases, which represent the code of our genetic material, could have originated from the surface of our planet ... Free oxygen did not exist ... DOI ... ....
These cores provide a basis for understanding hydrothermal explosion deposits in sedimentary sequences on the bottom of the lake and supplement recent and ongoing research on hydrothermal fluid systems venting on the lake floor, some of which are among the hottest hydrothermal vents in all of Yellowstone National Park.
The deep water cycle is hidden under the Earth's crust. NASA... No fish plumb its depths ... Or, most of it is ... Scientists already know that water can be dragged down to the mantle by subducting tectonic plates and brought back to the surface by things like volcanic eruptions, hydrothermal vents, and the creation of new crust at oceanic spreading centers.
The findings are evidence against the popular theory that life sprung from deep sea hydrothermal vents. In the enduring theory, it's thought that the heat and mineral-rich water in the hydrothermal vents attracted a huge diversity of microbial life, creating the ideal conditions where live organisms could form.
Digital illustration of microscopic life forms ...The idea is that the right basic ingredients mixed under the right conditions (perhaps like those found in an ancient hydrothermal vent) can form a “prebiotic soup,” from which a cascade of interactions between ingredients could ultimately set the stage for life ...

It teems with the sounds of breaking waves and blowing winds, bubbling hydrothermal vents and calving icebergs , all of which carry farther and travel faster underwater than in air.
In other areas of the MAR, spectacular hydrothermal vents often form where magma provides heat as it rises to the seafloor ... During dives, they expect to explore deep-sea coral and sponge habitats, potential hydrothermal vent and extinct polymetallic sulfide systems, fracture and rift zones, and the water column.
While much of public attention on Yellowstone focuses on its potential to produce large supereruptions, the hazards that are much more likely to occur are smaller, violent hydrothermal explosions ... of hydrothermal explosions, venting, doming, and faulting, GSA Bulletin (2022).
