IMPORTANCE OF WATER
Hubble
The Hubble Space Telescope has been monitoring activity in Jupiter's atmosphere for many years. Occasionally, it glimpses giant storms that suddenly appear, bursting from below the clouds. Evidence suggests that these storms are triggered when the heat locked up inside Jupiter warms the water clouds that lie just below the cloud tops. Juno will be able to study deep inside those cloud layers and learn what makes those storms churn.
The Hubble Space Telescope has imaged striking details of the famed planetary nebula designated NGC 2818, which lies in the southern constellation of Pyxis (the Compass). The spectacular structure of the planetary nebula contains the outer layers of a star that were expelled into interstellar space.
