MARFIK (Lambda Ophiuchi). Double stars are among the prettiest sights the sky has to offer. The best ones, like Albireo and many others, display striking color contrasts that are enhanced by visual proximity effects. But even the white “colorless” ones are attractive, especially if the two members are close together. Those of Marfik (the “elbow” of Ophiuchus), or Lambda Ophiuchi, are so close that they are, however, difficult to separate at the telescope, averaging just a second of arc – a 3600th of a degree – apart.
- Hudson Strait (Wikipedia)
Hudson Strait (French: Détroit d’Hudson) in Nunavut links the Atlantic Ocean and the Labrador Sea to Hudson Bay in Canada. This strait lies between Baffin Island and Nunavik, with its eastern entrance marked by Cape Chidley in Newfoundland and Labrador and Nunavut and Resolution Island, off Baffin Island. The strait is about 750 km (470 mi) long with an average width of 125 km (78 mi), varying from 70 km (43 mi) at the eastern entrance to 240 km (150 mi) at Deception Bay.
