While air is a gaseous delight unique to Earth, a team of astrophysicists have made a satisfying discovery: the direct observation of atomic oxygen on Venus’ dayside, confirming that the element crucial for our existence exists on both sides of the hellish planet.
On April 20, 2021, the spiritedly-named MOXIE experiment on Mars extracted 5 grams of oxygen from the Martian atmosphere, demonstrating a potential future capability of an established human presence on the Red Planet—and in o
We may some day be able to produce power from thin air—all thanks to bacteria living in dirt. Microbiologists at Australia’s Monash University have identified an enzyme within a bacteria found in soil that can produce electricity using nothing but hydrogen from the atmosphere.
