New research suggests that amino acids, the fundamental components of life, may have arrived on Earth carried by interstellar ...

Our solar system formed from a molecular cloud, which was composed of gas and dust that was emitted into the interstellar medium (ISM), a vast space between stars. On collapse of the molecular cloud, ...

In the beginning, there was soup. One leading explanation for how life arose on Earth is that simple chemicals in water, a primordial “soup,” formed in the hot, tumultuous early world and ...

Grab-and-go missions to asteroids have provided some of the most scientifically valuable samples since the Apollo ...

In 1929 British biochemist John Haldane (1892-1964) put forth the theory that the early atmosphere of Earth contained no free oxygen. Haldane and Soviet biochemist Aleksander Oparin (1894-1980) had ...

A key molecule for life may have formed in the cold, far-reaches of space, alongside budding stars and planets. Amino acids are the building blocks of proteins, making them vital for life on Earth.

While life on Earth is relatively new, geologically speaking, the ingredients that combined to form it might be much older than once thought. According to research published in ACS Central Science, ...

Life on Earth is complex and varied, but every living organism on the planet builds its proteins from the same set of 20 amino acids. All proteins in a human body, for example, are made up of some ...

Earth didn't always harbor life. But around 4 billion years ago, something in the environment changed, and systems with biological properties began to emerge. Many scientists believe a lively dance of ...
