Alien lifeforms probably won’t look anything like this. Life is pretty easy to recognize. It moves, it grows, it eats, it excretes, it reproduces. Simple.…
Using new geochemical models, SwRI scientists found that CO2 in Enceladus’ ocean may be controlled by chemical reactions at the seafloor. Integrating this finding with…
This infographic compares the characteristics of three classes of stars in our galaxy: Sunlike stars are classified as G stars; stars less massive and cooler…
This infographic shows the key results from a study that has revealed the interstellar thread of phosphorus, one of life’s building blocks.Thanks to ALMA, astronomers…
