- Giant star (Wikipedia)
A giant star has a substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity classes II and III. The terms giant and dwarf were coined for stars of quite different luminosity despite similar temperature or spectral type (namely K and M) by Ejnar Hertzsprung in 1905 or 1906.
- Ungava Bay (Wikipedia)
Ungava Bay (French: baie d’Ungava, pronounced [bɛ d‿œ̃ɡava]; Inuktitut: ᐅᖓᕙ ᑲᖏᖅᓗᒃ/ungava kangiqluk) is a bay in northeastern Canada separating Nunavik (far northern Quebec) from Baffin Island. Although not geographically apparent, it is considered to be a marginal sea of the Arctic Ocean for climatic reasons. The bay is roughly oval-shaped, about 260 kilometres (160 mi) at its widest point and about 320 kilometres (200 mi) in length; it has an area of approximately 50,000 km2 (19,000 sq mi). It is generally fairly shallow, under 150 metres (490 ft), though at its border with the Atlantic Ocean depths of almost 300 metres (980 ft) are reached.
