Hi JbhB682,

To ensure that we're on the same page (I think we are), the essential clause of the sentence is simply "Jupiter's moon Europa has long been considered far too cold to support life."

I ask because per my understanding, the initial modifier (green) already modifies the essential clause in Blue by describing 'why' ?
You're absolutely correct. This sentence has one essential clause and two modifying phrases:
Essential: Jupiter's moon Europa has long been considered far too cold to support life
Modifer: With surface temperatures estimated at minus 230 degrees Fahrenheit
Modifier: its 60 square miles of water thought to be frozen from top to bottom
Think about this example: The
big,
blue house
on the corner with yellow shutters,
which was owned by my father, was sold in 1982.
There are a LOT of modifiers here (in bold) and they are all absolutely permissible.
