Ocean World Update: Deep-sea Discovery Shines Light On Life In The Twilight Zone

by Keith Cowing

The ocean’s twilight zone is deep, dark, and — according to new research — iron deficient. No sunlight reaches this region 200 to 1,000 meters below the sea surface, where […]

Joint Genome Institute (JGI)-Enabled Research Demonstrates The Existence Of New Methane Makers

by Keith Cowing

Atmospheric levels of methane, a potent greenhouse gas, regulate Earth’s climate. Most methane is produced in environments without oxygen through a process called methanogenesis. Methanogenic microorganisms therefore play a critical […]

Oxygen Produced In The Deep Sea Raises Questions About Extraterrestrial Life

by Keith Cowing

Over 12,000 feet below the surface of the sea, in a region of the Pacific Ocean known as the Clarion-Clipperton Zone (CCZ), million-year-old rocks cover the seafloor. These rocks may […]

Comparative Raman Spectroscopy Of Astrobiology Relevant Bio-samples And Planetary Surface Analogs Under UV–VIS–IR Excitation

by Keith Cowing

We investigated the potential of a laser selection in the broad optical range, from ultraviolet through visible to infrared (excitation wavelengths of 325, 532, 785, and 1064 nm) for combined analysis […]
