A study of the subsurface ocean of Titan—the largest moon of Saturn—shows that it’s most likely a non-habitable environment, meaning any hope of finding life in the icy world is dead in the water.

An international team of radiation specialists, biologists and infectious disease experts has found four types of bacteria that are capable of surviving exposure to the hostile Mars environment.

Scientists have discovered, for the first time, water molecules on the surface of an asteroid.

Hidden beneath the heavily cratered surface of Mimas, one of Saturn's smallest moons lies a secret: a global ocean of liquid water.

Imagine exploring a system of life-rich worlds within easy traveling distance of each other. It’s a wonderful dream, but as a new study shows it isn’t likely that life exists in the system. It’s more likely the planets are barren and stripped of their atmospheres.

The integration of biology and spacefaring has led to the development of three interrelated fields: Astrobiology, Bioastronautics, and Space Bioprocess Engineering.

One day, perhaps in the not-too-distant future, a faraway planet could yield hints that it might host some form of life – but surrender its secrets reluctantly.

The future is full of questions for us earthly life-forms. How far can we take our search for life elsewhere? And if we find life beyond Earth, how will it change us?

Astronomers have found a new Super-Earth orbiting a red dwarf star about 137 light-years away. The planet is about 1.55 Earth’s radius and is inside the star’s habitable zone.

If interstellar objects (ISOs) have been coming to Earth for billions of years, could it be that they brought the ingredients for life with them?
