- 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.
- Messier 21 (Wikipedia)
Messier 21 or M21, also designated NGC 6531 or Webb’s Cross, is an open cluster of stars located to the north-east of Sagittarius in the night sky, close to the Messier objects M20 to M25 (except M24). It was discovered and catalogued by Charles Messier on June 5, 1764. This cluster is relatively young and tightly packed. A few blue giant stars have been identified in the cluster, but Messier 21 is composed mainly of small dim stars. With a magnitude of 6.5, M21 is not visible to the naked eye; however, with the smallest binoculars it can be easily spotted on a dark night. The cluster is positioned near the Trifid nebula (NGC 6514), but is not associated with that nebulosity. It forms part of the Sagittarius OB1 association.
