Travelers In The Night is your unique source of insider Information from the Asteroid Hunting and Space Communities.
The music is "Eternity" by John Lyell.

“Travelers in the Night” has more than 2,000 PRX free purchases as well as 160,200 downloads, 109,000 plays, and 15,250 followers on the internet.

It features an engaging and informative series of two minute, factual episodes about asteroids, comets, spacecraft, and other objects in space.

The script and a list of references for each program piece can be found on travelersinthenight.org.

The pieces are "evergreen" in that they are current but not dated.

The Travelers In The Night Pieces are written and produced by an observing member of the Catalina Sky Survey Team at the University of Arizona.

The Catalina Sky Survey has discovered nearly half of the Earth approaching objects known to exist.
