Light and Life: Exotic Photosynthesis in Binary Star Systems
The potential for hosting photosynthetic life on Earth-like planets within binary/multiple stellar systems was evaluated by modelling the levels of photosynthetically active radiation (PAR) such planets receive.

Abstract The potential of multi‐spectral investigations for planetary exploration strongly depends on the specific geologic environment and related science questions. In this work, we used a visible‐near infrared spectrometer, a laser‐induced breakdown spectroscopy (LIBS) instrument, and a Raman spectrometer for studying acid alteration of volcanic ...

Perchlorates on Mars enhance the bacteriocidal effects of UV light
Perchlorates have been identified on the surface of Mars. This has prompted speculation of what their influence would be on habitability. We show that when irradiated with a simulated Martian UV flux, perchlorates become bacteriocidal.

Outer space, the final frontier, is a hostile and unforgiving place for any form of life as we know it. The unique environment of space allows for a close simulation of Mars surface conditions that cannot be simulated as accurately on the Earth. For this

Life-Detection Technologies for the Next Two Decades
Since its inception six decades ago, astrobiology has diversified immensely to encompass several scientific questions including the origin and evolution of Terran life, the organic chemical composition of extraterrestrial objects, and the concept of ...

The Astrobiology of Alien Worlds: Known and Unknown Forms of Life
Most definitions of life assume that, at a minimum, life is a physical form of matter distinct from its environment at a lower state of entropy than its surroundings, using energy from the environment for internal maintenance and activity, and capable of

M Dwarf Planet Habitability [PDF]
The habitability of M dwarf planets has been debated greatly, as their parent stars possess both beneficial and detrimental qualities for the development of life.

Is the Pale Blue Dot unique? Optimized photometric bands for identifying Earth-like exoplanets
The next generation of ground and space-based telescopes will image habitable planets around nearby stars. A growing literature describes how to characterize such planets with spectroscopy, but less consideration has been given to the usefulness of ...
