- Perseus (Περσεύς in Greek) is one of the most famous Greek heroes. The characters in his story are represented by six constellations that occupy a substantial part of the sky. The constellation depicting Perseus lies in a prominent part of the Milky Way, which is perhaps why Aratus termed him ‘dust-stained’.
- North Bismarck Plate (Wikipedia)
The North Bismarck Plate is a small tectonic plate located in the Bismarck Sea off the northeast coast of New Guinea. It is currently regarded as a relic or inactive plate by most. At one time it was called the Manus Plate, but this term was later used for a modelled microplate at the south east boundary of the North Bismarck Plate.
