- Cassiopeia was the vain and boastful wife of King Cepheus of Ethiopia, who stands next to her in the sky. They are the only husband-and-wife couple among the constellations. Classical authors spell her name Cassiepeia, from the original Greek Κασσιέπεια, but Cassiopeia is the form used by astronomers.
- Juan de Fuca Plate (Wikipedia)
The Juan de Fuca Plate is a small tectonic plate (microplate) generated from the Juan de Fuca Ridge that is subducting beneath the northerly portion of the western side of the North American Plate at the Cascadia subduction zone. It is named after the explorer of the same name. One of the smallest of Earth’s tectonic plates, the Juan de Fuca Plate is a remnant part of the once-vast Farallon Plate, which is now largely subducted underneath the North American Plate.
