Believe it or not, we can (kind of) measure the air pressure of early Earth! Blue-green algae's response to different nitrogen pressures may tell us what fossils to look for and what those fossils tell us about ancient air pressure.

A crater on Mars may be a future landing site Rock formations on the Jezero Crater on Mars give us clues that there were probably active rivers there at some point.

Here on Earth, scientists study layers of sediment like dirt and sand to better understand how rocks form. The same contextual clues geologists use to explain how sedimentary rocks form on Earth can also be applied to extraterrestrial planets. Recent READ MORE

What Could Have Created the Ancient Martian Rivers? Researchers created a new model for climate cycling on early Mars, aiming to explain the soil patterns that have been observed on the planet.

by Larissa L. Cavalcante Blue Marble Space Young Scientist Program Water is essential for life. When searching for life in the universe, the first thing researchers do is “follow the water”. Mars is no exception. Finding evidence of water on Mars READ MORE

The Information Flow of Life Our genes are the software and our traits are the hardware, one pushing the development of the other.

From chemistry to biology to social networks, specific shared principles should guide how information is organized and how it cycles through these stacks. If this theory of common principles can be demonstrated, we would gain a deeper understanding of the flow of information through life.

Saturn’s Moon Enceladus May Have Conditions For Life In a last scientific hurrah, the Cassini spacecraft has detected that hydrogen is being ejected from the moon’s ice-covered ocean
