In contemporary belief angels are often described either the "classical" form (human countenance with wings), in the form of extraordinarily beautiful or radiant human beings, or as beings of light.
In Gnosticism, Aeons bear a number of similarities to Judaeo-Christian angels, including roles as servants and emanations of God, and existing as beings of light.
In Battlestar Galactica, the Seraphs are the same angelic "Beings of Light" mentioned in "The Book of the Word", the dominant Colonial Scripture, and that these beings have played a part in human society.
In Out of the Silent Planet by C. S. Lewis, the protagonist meets eldila, mysterious beings of light native to the void of interplanetary space (who are actually what Christianity defines as "angels", and who are also identified as Mars, Venus and other deities of Greek and Roman mythology)
