Two recent discoveries in astrobiology challenge many of our assumptions about an integrated biological community on Earth. At the microbial level, it seems that there may be previously hidden biospheres that exist on Earth alongside our more familiar neighbors. One such community has been found deeply buried underground, while the other lives in the sea alongside more familiar life forms. Potentially among the most important recent discoveries in astrobiology is the finding of deeply buried...

NASA -- Dr. Pan Conrad is on a quest. Her search for signs of life in extreme environments has taken the JPL astrobiologist from the icy realms of the Arctic and the dry valleys of Antarctica to the scorching sands of Death Valley, California. The hunt landed Conrad at the bottom of the ocean with Oscar-winning director James Cameron and a role in his film "Aliens of the Deep." Last year, Cameron invited Conrad and her JPL colleague Dr. Lonne Lane to join him on an expedition to one of the...

A team of researchers, including a photosynthesis expert from ASU, has found evidence of photosynthesis taking place deep within the Pacific Ocean. The team found a bacterium that is the first photosynthetic organism that doesn't live off sunlight but from the dim light coming from hydrothermal vents nearly 2,400 meters (7,875 feet) deep in the ocean. The discovery of the green sulfur bacteria living near hydrothermal vents off the coast of Mexico has significant implications for the...

UNITED NATIONS -- Leaps in technology have made the darkest reaches of the sea much easier to explore, necessitating new rules to govern the precious resources of the deep, researchers said in a report. The report released Thursday said that scientists have begun to focus on the possible human health benefits to be gained from genetic material of "extremophiles," the organisms that thrive under extreme conditions in the deep. Now that so-called "bioprospecting" has become more feasible,...

Santa Barbara, Calif. -- New keys to understanding the evolution of life on Earth may be found in the microbes and minerals vented from below the ocean floor, say scientists at the University of California, Santa Barbara. The UCSB scientists are making new contributions to this field of inquiry in their studies of seafloor hydrothermal fluid discharge into the Earth's oceans, which has been occurring ever since the oceans first formed four billion years ago. Conditions below the sea floor...

Film director and exploration enthusiast James Cameron (Titanic, Aliens) gave Stanford graduate student Kevin Hand a chance to search for "alien" life close to home -- a mere 2 miles below the ocean surface -- as part of Cameron's IMAX documentary, Aliens of the Deep, which opens today. Astrobiology Magazine -- Stanford graduate student Kevin Hand explores the potential for life on Europa, an icy moon of Jupiter, for his doctoral work with geological and environmental sciences Associate...

(AP) -- Photographs taken by a spacecraft orbiting Mars indicate that active volcanoes may still exist on the red planet, further eroding its image as a dead world and offering prime sites to prospect for signs of Martian life. Images from the European Space Agency's Mars Express Orbiter indicate geologically recent volcanic activity in the summit craters of five Martian volcanoes, with some areas showing activity as recently as 4 million years ago. Though long in human terms, 4 million years...

The limits to life have consistently listed carbon-based organisms as central. While methane-consuming microbes are still carbon-based, they do offer novel ways to extract energy even without light or oxygen. Their role in our solar system is a subject of fruitful speculation. Astrobiology Magazine -- A team of University of Minnesota scientists has discovered how iron- and chromium-rich rocks can generate natural gas (methane) and related hydrocarbons when reacted with superheated fluids...

Pompeii Worm, Alvinella pompejana
2014-01-12 00:00:00

The Pompeii worm (Alvinella pompejana) is a species of polychaete worm, or bristle worm that is only found in the Pacific Ocean. It resides at hydrothermal vents, making it an extremophile, and was first discovered French marine biologists of the coat of the Galapagos Islands in the 1980s. It was described by Lucien Laubier and Daniel Desbruyeres as a deep-sea polychaete that could withstand extreme amounts of heat. The Pompeii worm can reach an average length of up to five inches and is...

Bathymodiolus Thermophilus
2013-04-16 18:50:25

Bathymodiolus thermophilus is a species of large, deepwater mussel, a marine bivalve mollusk belonging to the family Mytilidae. The species was discovered at abyssal depths when submersible vehicles began exploring the deep ocean. It occurs on the sea bed, frequently in large numbers, close to hydrothermal vents where hot, sulphur-rich water wells up through the floor of the Pacific Ocean. This is a very large mussel with a dark brown periostracum, growing to a length of about 8 inches....

callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
