Found Dozens of Ancient Cryovolcanoes on Ceres! SciShow News

The video discusses cryovolcanoes, which emit slushy ices instead of lava, found on gas giant moons, Pluto, and Ceres. NASA's Dawn spacecraft discovered 32 cryovolcano remnants on Ceres, revealing insights into its geological history. Cryovolcanoes differ from Earth's volcanoes, with less activity and icy magma originating from the crust. The video also covers satellite flares, particularly Iridium flares, which are becoming rare as new satellites replace the old ones. These changes impact both sky watchers and astronomers.

What is the significance of Iridium flares and how do they occur?
