NASA’s upcoming James Webb Space Telescope (JWST) will be used to study two of the most fascinating moons in our Solar System – Europa and Enceladus, also known as “ocean worlds” since both have […]

'Strange Life' on Titan? New Organic Molecule Discovery Could Mean It's Possible

Titan, as seen in radar images from NASA’s Cassini spacecraft, is a complex world with methane/ethane rain, rivers, lakes and seas. Could it support life of some kind? Image Credit: NASA/JPL

Saturn’s largest moon Titan is a bizarre place with a thick and hazy nitrogen atmosphere, vast hydrocarbon dunes and methane/ethane rain, rivers, lakes […]

New Findings from Curiosity Hint Ancient Mars Lake 'Favorable for Different Microbial Life'
