Water on Ganymede, and NASA Needs Your Help!

The video discusses the discovery of a vast subsurface ocean on Jupiter's moon Ganymede, using Hubble's Space Telescope Imaging Spectrograph to study auroras. This discovery suggests Ganymede has more water than all of Earth's oceans. The video also highlights NASA's initiative to involve citizen scientists in asteroid tracking through the Asteroid Data Hunter Challenge, which aims to improve asteroid detection algorithms. The winning algorithm is more sensitive and produces fewer false positives, allowing users to upload telescope images and identify asteroids, contributing to global data sharing.
