A picture snapped from the International Space Station (ISS) by NASA astronaut Nichole Ayers has captured a lesser-seen view ...

These molecules could have come from the breakdown of fatty acids that existed 3.7 billion years ago before being preserved in sediments laid down by an ancient lake on the Red Planet. While ...

Molecules transfer their kinetic energy to other molecules through conduction. When a fast-moving molecule hits a slower-moving molecule, the slower molecule speeds up (and turns more red) and the ...

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

Using their new approach, they were able to build molecules that emit red, orange, yellow, green, or blue light, which could make acenes easier to deploy in a variety of applications.

The red bricks should form a cross or lowercase “t” shape. Attach four red oxygen bricks to an orange phosphorous brick to make a phosphate group. Photo credit: Sandy Roberts, based on MIT Edgerton ...

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

While the presence of these molecules is not proof of ancient life on Mars, scientists say it shows we could detect chemical signatures of past life, if it ever existed.
