Splet15. okt. 2024 · This suggests the long-term presence of a water vapor atmosphere on Europa’s trailing hemisphere. On the leading hemisphere, the Hubble data are consistent with a pure oxygen atmosphere everywhere across the moon disk. “This result lays the groundwork for future science based on upcoming missions to the Jovian moons,” Dr. … Splet07. jan. 2024 · Close-up of Europa's Trailing Hemisphere. This complex terrain on Jupiter's moon, Europa, shows an area centered at 8 degrees north latitude, 275.4 degrees west longitude, in the trailing hemisphere.
