A clear day in San Fran

A clear day in San Fran Bay Today’s Image of the Day from NASA Earth Observatory features a clear December day across San Francisco Bay. In the summertime, the region is typically covered by a layer of low clouds. 

The photograph, A clear day in San Fran which was taken by an astronaut onboard the International Space Station, captures a mix of urban and natural areas. North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be described as the northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Tectonic Plate, Greenland is included as part of North America geographically. North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), about 16.5% of the Earth’s land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the fourth by population after Asia, Africa, and Europe. 

The Golden Gate Bridge is one of the famous landmarks of the San Francisco Bay that stand out to astronauts. The bridge is part of Route 101, the longest highway in California.

Alcatraz, home to the well-known prison, is now part of the Golden Gate National Recreational Area. 

Only one fatal shark attack has ever been documented within San Francisco Bay, yet a common myth is that Alcatraz is surrounded by man-eating sharks.

According to NASA, the Golden Gate Park acts as an “urban oasis” amidst the dense, well-organized, square city blocks.

Spanning more than 1,000 acres, the park is home to the San Francisco Botanical Garden.
