I haven’t done one of these in a while. Take a guess as to what this might be. Here are some possibilities:
a) luminous bacteria in the deep ocean (biology)
b) aurora borealis (physics)
c) a ring of Saturn (astronomy)
d) kirlian aura (paranormal science)
e) a portion of a work of modern liturgical art
D is my guess.
E.
aurora borealis
