Previous estimates of molecular oxygen around the Jovian moon topped out at over 2,000 pounds being produced per second. A new measurement suggests it's way lower than that.

The subsurface ocean of Jupiter’s moon Europa may have far less oxygen—and less potential for life—than previously believed, according to data from NASA’s Juno spacecraft ...

The team found that about 13 to 40 pounds of oxygen is generated each second by Europa’s surface. That’s over 1,000 tons per day, about enough to fill the Dallas Cowboys football stadium 100 ...

The measurements indicate that this may amount to only 1.5cm of Europa’s surface per million years, which is less than we had thought. So Europa is constantly losing oxygen due to pickup ...

Like Earth, Europa is believed to have a rocky mantle and an iron core. The findings, published Monday in the journal Nature Astronomy, show Europa's producing around 26 pounds of oxygen every second.

A SpaceX Falcon Heavy launched NASA's Europa Clipper mission Monday to investigate Europa, a moon of Jupiter's that has an icy surface which may have an ocean under it, teeming with life.

"In less than a month, the journey begins. @EuropaClipper is a mission crafted with one overarching goal: to determine if Jupiter’s icy moon, Europa, has conditions suitable for life.
