Hydrothermal vent

There are 67 moons that orbit Jupiter but the four largest are Io, Europa, Ganymede and Callisto. The man who found the moons, was Galileo Galilei who was born in Pisa in 1564, in 1581 he went to the University of Pisa to study medicine. But was sidetracked by mathematics, in 1609 is when he built his first telescope but it wasn’t no ordinary telescope. This telescope Galileo built he could discover uncharted territory. To Galileo it seemed plainly obvious that the universe was not the perfect…

that had to evolve in perpetual darkness. The Challenger Deep in the Mariana Trench is very cold, and highly pressurized which forces all of the living things that live there to adapt to its conditions. The floor of Challenger Deep features hydrothermal vents formed by spreading tectonic plates which release hydrogen sulfide and other minerals which are consumed by the basophilic bacteria which are then consumed by other microorganisms, which are consumed by fish. Crabs, Anglerfish, Ghost fish…

Humanity has an inherent drive for superior understanding of our Solar system and to find environment similar to that of planet Earth which could contain life. As consequence, there have been several space missions to analyse climate, assess data and search for geological evidences of life. With net expenditure of approximately three billion dollars, the Cassini-Huygens space mission to Saturn system was a joint assignment among finest space agencies; National Aeronautics and Space…

PCR (Polymerase chain reaction) Polymerase chain reaction (PCR) is a laboratory method that is used to form number of copies of a specific region of DNA interested in. The principle of the polymerase chain reaction is based on the natural replication process of DNA and complementary nucleic acid hybridization. The goal of the PCR is to produce required amount of the target DNA region that is be analyzed. PCR amplified DNA is sent for sequencing and visualized by gel electrophoresis. It also can…

industry to directly mitigate the negative impacts as well as enhance any potentially beneficial impacts. Exploration 1. Locating Exploratory technology for deep-sea mining is currently in use and is similar to petroleum exploratory technology. Active vents can be located from the plume, which can be detected up to 10 km away,…

Renowned American author H. P. Lovecraft once wrote, “Blue, green, grey, white, or black; smooth, ruffled, or mountainous; that ocean is not silent”. Presently, the earth is estimated to be around 70% water, yet humanity has only explored less than 5% of the oceans. Imagine what we could learn from the unknowns of the most treacherous depths, and to what possibilities could we utilize all the information gathered? One anomaly quite intriguing is the diverse sea-life, which proceeds to prosper by…

The observation of extremophiles proves the remarkable persistence of life in harsh and forbidding environments, existing under extremely high pressures and temperatures near hydrothermal vents. Such discoveries provide hope in finding life in the severe Martian environment, whether present or past. Many ethicists debate the moral status of microbial communities in consideration of space exploration because such activities could affect…

It is also home to the largest concentration of geysers in the world and one of the biggest hydrothermal systems. Geologists have found evidence of 6 older calderas southwest of Yellowstone that extend into Idaho. The formation of Yellowstone occurred over a more than 2 million year period, but is actually the youngest in the geological history of…

Producers Marine snow- Marine snow is the “rain of food” that slowly falls from the top or middle layers of the ocean zones to the ocean floor. It can also be called detritus. The marine snow is the nutrient that feeds at the bottom of the food pyramid. It’s mostly made up of dead and decomposing animals, dejection, silt and other organic wastes that had been washed into the sea from land. The marine snow got it’s name because it resembles snow with the white fluffy components. As the dead…

it. Other questions that the ash brought were if the land covered by it would be usable afterward as a lot of crops were lost. "Volcanic ash consists of very fine rock and mineral particles less than 2 mm in diameter that is ejected from a volcanic vent". Science Daily After the 1980 eruption scientists realized that volcanic ash won't really cause any serious health issues, the effects might be eye irritation or harder time breathing. The most serious damage can be if the volcanic ash causes…
