Infrared photosynthesis: A potential power source for alien life in sunless places
A new study explores the potential for photosynthetic life to persist in such sun-starved conditions. The research aims to shed light, as it were, on how organisms could live off of the dim infrared emissions from hydrothermal vents on alien worlds. Tantalizingly, such vents are theorized to exist beneath the surface of Jupiter’s ice-covered, oceanic moon Europa.
“When we became aware of bacteria using infrared light to photosynthesize, we felt very curious about checking the photosynthetic potential with this light because this is one measure of whether life could thrive around hydrothermal vents,” said Rolando Cardenas, a physicist at Central University “Marta Abreu” de Las Villas in Santa Clara, Cuba and a coauthor of the paper published in the May issue of Astrophysics and Space Science…>>>more
