Hubble finds first proof of water vapor on Jupiter’s moon Ganymede

[ad_1] In 1998, Hubble’s Area Telescope Imaging Spectrograph (STIS) took these first ultraviolet (UV) pictures of Ganymede, which revealed a selected sample within the noticed emissions from the moon’s environment. The moon shows auroral bands which are considerably just like aurora ovals noticed on Earth and different planets with magnetic fields. This was an illustrative proof for the truth that Ganymede has a everlasting magnetic area. The similarities within the ultraviolet observations have been defined by the presence of molecular oxygen (O2). The variations have been defined on the time…
