NASA Surprised by Cracks in Ancient Martian Mud Discovered by Mars Curiosity Rover (scitechdaily.com)

New research suggests the same conditions that created the cracks could have been favorable to the emergence of microscopic life. Scientists aren’t entirely sure how life began on Earth, but one prevailing theory posits that persistent cycles of wet and dry conditions on land helped assemble the

TESS has found thousands of possible exoplanets: Which ones should JWST study? (phys.org)

There are more than 5,000 confirmed exoplanets in our galaxy. That number is going to rise significantly in the next decade. The Transiting Exoplanet Survey Satellite (TESS) has already cataloged more than 4,000 candidate exoplanets, and the PLAnetary Transits and Oscillations of stars (PLATO) is scheduled to launch in 2026.
