"Europa's Oxygen Levels Lower Than Expected, Dimming Hope for Habitability"

New data from NASA's Juno spacecraft suggests that Jupiter's moon Europa produces much less oxygen than previously thought, with estimates substantially lower than earlier studies. The findings have implications for the moon's potential habitability, as Europa is believed to have a large ocean beneath its icy surface. The lower oxygen estimates challenge earlier observations and highlight the need for further research to confirm the latest findings, as NASA prepares to launch its Europa Clipper mission to search for signs of life on the moon.
