Space Views from the Hubble Telescope

This card ~ 'Atmospheric Changes on Neptune' ~ arrived on July 7.

This is the caption on the back:

"This view of Neptune shows the planet's rapidly changing weather conditions.  Neptune's remarkably dynamic atmosphere, composed of hydrogen, helium, methane, and hydrocarbons such as ethane and acetylene, changes over just a few days, possibly as a result of the temperature difference between the planet's hot core and its frigid (-260 degrees F) cloud tops."
