Timelapse of Two Travelers —
Lemmon orbits with a majestic and dynamic tail spanning a few degrees.
SWAN silently sails with almost no tail yet proudly marks its presence with a green glowing nucleus, a signature of diatomic carbon.

Seyfert’s Sextet, found between Hercules and Serpens, consists of 5 galaxies and a long tail of stars of one of them. NGC 6027d is not gravitationally related and is actually 955 million LY away! The other 5 are only 190 million LY away. Such old photons!
