In 1996, a Nasa team announced a Martian meteorite discovered in Antarctica bore signs of past alien life. Specimen ALH84001 ...

The molecules may be remnants of fatty acids, which form cell membranes in Earth’s organisms, though they might have formed through a non-biological process ...

The Curiosity rover detected the largest organic molecules to date on Mars, which may be fragments of fatty acids, or some of ...

Fifty years ago, scientists recovered samples of potential extraterrestrial life, but may have unintentionally destroyed it ...

Unlocking the origins of life starts with understanding how simple space molecules turned into complex building blocks. To do ...

Additional organic compounds, he suggests, could have formed later in Earth’s primordial soup or were delivered to our planet by comets ... to the possibility of life on other planets.

A new study explores the possibility of microbial life in Titan's deep ocean—and why it may be harder to find than we think.

Two NASA rovers on Mars recently made two independent discoveries further indicating that ancient life may have once existed on the Red Planet.

So, if life exists on Titan, it might not resemble the thriving, teeming ecosystems we know. Instead, think of isolated oases — tiny, slow-growing communities, perhaps tucked away in warmer pockets, ...

They’re also trying to figure out how organic compounds fluoresce in subfreezing conditions like those on icy moons thought to harbor habitable environments and the building blocks for life.

The organic compounds, which include decane ... determine whether life ever existed anywhere beyond our planet. Curiosity landed in Gale Crater on August 6, 2012. More than 12 years later ...
