The Cosmic Collision That Made Earth Habitable and Gave Rise to Life

Recent research indicates that Earth formed quickly within three million years of the Solar System's birth, but was initially dry, lacking water and carbon compounds. The planet's volatile content was likely delivered later through impacts, such as the collision with Theia, which also led to the formation of the Moon. This late delivery of volatiles was crucial for making Earth habitable, highlighting the importance of impact history in planetary habitability.

Revealing the Birth of Earth's First Cells

Researchers from The Scripps Research Institute have proposed a plausible pathway for the formation of the membranes of the first cells on Earth, suggesting that a chemical process called phosphorylation may have played a crucial role in the development of protocells more than 3.5 billion years ago. By replicating early Earth conditions in the lab, the team was able to demonstrate that phosphorylation could have been involved in the creation of more complex vesicles, similar to protocells. This finding sheds light on the chemical environments of early Earth and provides insights into the origins and evolution of life, while also offering implications for the study of life on other planets.
