If one is referring to the German literary movement, the phrase would not be translated, but in other other contexts, Storm and Stress would be OK.

Sturm und Drang (the conventional translation is "Storm and Stress"; a more literal translation, however, might be storm and urge, storm and longing, or storm and impulse) is the name of a movement in German literature and music taking place from the late 1760s through the early 1780s in which individual subjectivity and, in particular, extremes of emotion were given free expression in response to the confines of rationalism imposed by the Enlightenment and associated aesthetic movements.

This is about astronomy. Therefore I believe you have to leave the quote in the original and in quotation marks. Any translation would skew the meaning strangely.
