Sentences with phrase «around hydrothermal vents»

Suggestions of hydrothermal activity on Europa led researchers to speculate that life there could resemble ecosystems around hydrothermal vents on Earth and would survive on chemosynthesis, extracting energy from chemicals.
The revolutionary discovery in the 1970s of a thriving complex marine ecosystem around the hydrothermal vents of the Galapagos Rift on the ocean floor of the eastern Pacific forever changed our understanding of habitability showing that life could also arise and flourish in the complete absence of sunlight in conditions that were utterly toxic to any other life forms on Earth.
Potential Europan habitats include deep - sea colonies based on heat - loving bacteria like those found around hydrothermal vents on Earth's ocean floor.
The unusual changes in currents may help explain how the larvae of the heat - loving creatures living around hydrothermal vents are dispersed through long stretches of near - freezing waters to reach other warm havens, says Adams.
If an iPhone had the properties of amino acids and such around hydrothermal vents or boiling pools, they we would see it, but anything else and your proposal is ridiculous.
Argonaut octopus; courtesy of Cabrillo Marine Aquarium / YouTube The vast majority of octopus species live along the sea floor — whether that is in the sandy shallows off a tropical coast or in the dark depths around hydrothermal vents.
Other researchers, however, say that the fossil stromatolites were not formed by living organisms, but by physical and chemical processes around hydrothermal vents.

1 Around Hydrothermal Vents The scalding hot, sulfur - laden waters of hydrothermal vents, where ocean water heated by magma reemerges through cracks in the seafloor, are teeming with microscopic life.
The chemotrophic bacteria that live in and around the hydrothermal vents are able to use chemical energy from the mineral - rich water.
