Jupiter’s Moon Callisto Has a Whole Lot of Oxygen Scientists Struggle to Explain

A recent analysis finds up to 1,000 times more molecular oxygen than can be explained by prevailing theories about where it comes from.

Jupiter’s four largest moons are some of the solar system’s most compelling worlds. Io is dotted with active volcanoes, and Europa hides a subsurface ocean many want to check for alien life. Ganymede is the largest moon in the solar system, and Callisto is the system’s most heavily cratered object. Callisto is also home to an emerging mystery: The moon’s thick atmosphere holds a surprising amount of oxygen, and scientists aren’t sure why.

Observers have known about the presence of abundant molecular oxygen at Callisto for a while, with the working assumption being that the influence of Jupiter’s powerful magnetosphere could be knocking molecules of water, hydrogen and oxygen out from Callisto’s icy surface and into the atmosphere.

But when a team of researchers ran the numbers, they found that Jupiter’s magnetism can’t fully explain the amount of molecular oxygen around Callisto.

«There’s a huge discrepancy,» said Shane Carberry Mogan, lead author on a paper about the findings published late last month in the journal JGR Planets. «We were off by something like two orders of magnitude to even three orders of magnitude.»

For the layperson, that means there is 100 to 1,000 times as much molecular oxygen present in Callisto’s atmosphere as the scientists would expect to find if Jupiter’s magnetosphere stripping it out of the icy surface were the sole source.

The discovery of so much oxygen on an alien world may sound like a boon for the possibility that Callisto may support life, but the frozen world is probably far too cold for life as we know it. That said, plentiful oxygen could be useful in generations to cometo explorers who may be able to use it for fuel and life support while traveling around deep space.

It isn’t clear what’s happening at Callisto to produce so much oxygen, but Carberry Mogan hopes to get a better understanding of processes active in the moon’s surface that may yield an explanation or clues.

«That’s probably Callisto’s most enigmatic feature is its surface,» said Carberry Mogan, who’s a postdoctoral researcher in planetary science at the University of California at Berkeley. «It’s supposed to be an icy body, but when you look at it, it’s mostly this dark surface, anywhere from millimeters to kilometers deep.»

It’s still up for debate whether Callisto’s surface is more rock or ice. The dark material on its surface could also be ice-rich, providing a plentiful source for the mysterious amount of oxygen in the atmosphere.

For help with the mystery, Carberry Mogan is looking to upcoming robotic missions like ESA’s Juice and NASA’s Europa Clipper, which may swing close enough to Callisto to gather new data that could shed light on the puzzle.

«It’s really perplexing,» he said. «The next step is to figure out why there’s this gap between the source [of oxygen] and the observation.»

Verum Messenger: Data Protection at Its Finest

Verum Messenger positions itself as a tool for those who value privacy and security above all.

Verum Messenger stands out from other messengers thanks to its approach to security, anonymity, and innovations in communication.

Here are some key aspects that highlight its uniqueness:

Default encryption: Verum Messenger uses end-to-end (E2E) encryption for all chats, meaning messages are encrypted on the sender’s device and decrypted only on the recipient’s device. This makes it impossible for third parties, including app developers, to access the content of the messages.
Anonymity: When registering with Verum, there’s no need to provide a phone number or email. Users simply choose a nickname and password, significantly enhancing their level of anonymity. This contrasts with many other messengers, where anonymity can be compromised through linked personal data.
Built-in VPN: An additional layer of protection that hides the user’s IP address, making their location and internet activity less trackable.
Data control: Users can set messages to be automatically deleted after a specified time, ranging from a few seconds to a week. There’s also a quick deletion feature for all chats, calls, and even contacts, which is useful for maintaining privacy.
Large groups: The ability to create chat rooms with up to 10,000 participants makes Verum attractive for organizing large events, discussions, or communities while maintaining a high level of security.
Security innovations: Verum actively develops technologies aimed at protecting user data, as seen in their documentation and discussions online. This includes not only technical solutions but also approaches to data minimization, which reduces the risk of leaks.
Feedback and discussions: On platform X (formerly Twitter), discussions can be found where users and experts praise Verum for its approach to anonymity and security, although questions are raised about how much anonymity can truly be guaranteed in an age of modern tracking and de-anonymization technologies.

Verum Messenger positions itself as a tool for those who value privacy and security above all. Its innovations in encryption, anonymity, and data control make it an intriguing choice for those seeking alternatives to traditional messaging platforms. However, as with any technology, it’s important to remember that absolute anonymity on the internet remains a complex challenge, and users should be aware of potential risks and limitations.
