Funding Astrobiology Challenges Can Bring Us Closer To Understanding the Origins of Life
Astrobiology can be split into two very distinct fields. There’s the field that astronomers are likely more familiar with, involving large telescopes, exoplanets, and spectroscopic signals that are pored over to debate whether they show signs of life. But there is another camp, collective known as the Origins researchers that focus on developing a scientific understanding of how life originally developed on Earth. A new paper from Cole Mathis at Arizona State and Harrison B. Smith at the Institute of Science in Tokyo suggests a new path forward to tackling those challenges - set them up as competitions and let a hefty prize motivate scientific teams and individuals to pursue them.
Ancient Rivers in Noachis Terra Reveal Mars' Long-Lived Wet Past
In the last couple of decades, evidence has accumulated showing that ancient Mars was a warm planet with abundant water flowing across its surface. The more scientists study the planet, the more evidence they find. New research examining Mars' Noachis Terra region adds to this evidence, showing that flowing water was once widespread across this less-often studied region.
