These icy bodies contain organic molecules — and don’t fall into any known category of celestial object we’ve seen before.

New research suggests “microlightning” exchanges among water droplets in Earth’s early atmosphere may have sparked the ...

NASA's Curiosity Rover has discovered long carbon chains on Mars. On Earth, molecules like these are overwhelmingly produced by biological processes.

But real lightning would have struck infrequently—and mostly in open ocean, where organic compounds would have quickly ...

The molecules, while not a direct sign of life, still signal the existence of complex chemistry on the Red Planet.

While previous studies say volcanic or atmospheric lightning may have triggered chemical reactions that created organic ...

We may be starting to get a grasp on what kick-started life on Earth – and it could help us search for it on other planets ...

A team of scientists just discovered the longest organic molecules yet seen on Mars, the fourth planet from the Sun and and a ...

Saturn’s largest moon might not be the barren world it seems. Beneath Titan’s icy crust lies a vast ocean of liquid ...

NASA’s Curiosity Mars rover has detected the largest organic (carbon-containing) molecules ever found on the red planet. The ...

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

which are organic molecules that are chemical building blocks of life on Earth and help form cell membranes. But such compounds can also be formed without the presence of life, created when water ...
