- Riverworld (Wikipedia)
The Riverworld is a fictional planet and the setting for a series of five science fiction novels (1971–1983) by American author Philip José Farmer (1918–2009). The Riverworld is an artificial, or heavily terraformed, planet where all humans (and pre-humans) who ever lived throughout history have been restored to life. The novels (and a few shorter works) explore interactions of resurrected individuals from many different cultures and time periods. The underlying theme is quasi-religious. The motivations and ethics of the unknown intelligences that created the Riverworld and its inhabitants are explored.
- Messier 71 (Wikipedia)
Messier 71 (also known as M71, NGC 6838, or the Angelfish Cluster) is a globular cluster in the small northern constellation Sagitta. It was discovered by Philippe Loys de Chéseaux in 1745 and included by Charles Messier in his catalog of non-comet-like objects in 1780. It was also noted by Koehler at Dresden around 1775. Messier 71 is also known as NGC 6839 and The Bernardo Star, though this identification is very uncertain.
