A new study is challenging long-held beliefs about the origins of life and the building blocks that led to the first genes ..

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.

Humanity’s search for life on Mars has taken a significant step forward with the discovery of organic molecules that resemble key building blocks of life on Earth. Since landing in 2012, NASA’s ...

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

The discovery of these organic molecules offers crucial insights into potential biological processes on early Mars, but to be clear, it’s not evidence of past or present life.

According to astronomers, there are approximately 200 billion trillion stars in our observable universe — chances are, there’s life out there somewhere.

The meteor fragments returned by OSIRIS-REx shed light on the entwined history of water and the chemical ingredients of life in the solar system.

In samples NASA brought back from the asteroid Bennu, scientists have discovered of organic compounds, including key building blocks of life like amino acids.

Scientists have detected organic compounds and minerals necessary for life in the samples collected by the OSIRIS-REx mission from a near-Earth asteroid named Bennu.

Researchers have detected organic compounds and minerals necessary for life in unprecedented samples collected from the near-Earth asteroid Bennu, adding evidence to the idea that asteroids likely ...

Amino acids, or molecules that combine to form proteins, are some of the building blocks of life. The researchers found 14 of the 20 amino acids that are used in biology to build proteins, and 19 ...
