The acidity of the atmosphere is increasingly determined by carbon dioxide and organic acids such as formic acid. The second of these impact the growth of clouds and pH of rainwater. But the chemical ...

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, ...

The first building blocks of life on Earth may have formed thanks to eruptions from our Sun, a new study finds. A series of chemical experiments show how solar particles, colliding with gases in 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, ...
