Oceans Are Vital for Life On Other Planets
New research published today in the journal Astrobiology shows the vital role of oceans in moderating climate on Earth-like planets. Until now, computer simulations of habitable climates on Earth-like planets […]
Abiotic Ozone and Oxygen in Atmospheres Similar to Prebiotic Earth
The search for life on planets outside our solar system will use spectroscopic identification of atmospheric biosignatures. The most robust remotely-detectable potential biosignature is considered to be the detection of […]
Mars Mineral Could be Linked to Terrestrial Microbes
Scientists have discovered that the earliest living organisms on Earth were capable of making a mineral that may be found on Mars. The clay-mineral stevensite has been used since ancient […]
Prospects for Detecting Oxygen, Water, and Chlorophyll in an Exo-Earth
The goal of finding and characterizing nearby Earth-like planets is driving many NASA high-contrast flagship mission concepts, the latest of which is known as the Advanced Technology Large-Aperture Space Telescope […]
Fuel Cells May Have Answers To Origin of Life on Earth
How life arose from the toxic and inhospitable environment of our planet billions of years ago remains a deep mystery. Researchers have simulated the conditions of an early Earth in […]
Lichen on Mars
Humans cannot hope to survive life on Mars without plenty of protection from the surface radiation, freezing night temperatures and dust storms on the red planet. So they could be […]
