European Space Agency shares mesmerizing image of Ram Setu linking India and Sri Lanka
European Space Agency (ESA) has released an image of the Ram Setu, also known as Adam's Bridge, captured by its Copernicus Sentinel-2 satellite. This chain of shoals stretches 48 km, connecting Rameswaram Island in India and Mannar Island in Sri Lanka. It separates the Gulf of Mannar from the Palk Strait.
The satellites carry an innovative wide swath high-resolution multispectral imager with 13 spectral bands and provide a new perspective of land and vegetation.
Formation and Historical Context of the Ram Setu
Numerous theories exist about the formation of Ram Setu. Geological evidence indicates these limestone shoals are remnants of a land bridge that once connected India and Sri Lanka. Historical records suggest this natural bridge was traversable until the 15th century, gradually eroding due to storms. The ESA noted, “Some of the sandbanks in the Ram Setu are dry, and the sea in this area is very shallow, ranging from only 1 to 10 meters deep.”
Ecological and Environmental Importance
Both ends of Ram Setu are part of protected national parks. The sand dunes serve as breeding grounds for birds like the brown noddy, while the shallow waters host various species of fish, seagrasses, dolphins, dugongs, and turtles. Mannar Island, covering around 130 square kilometers, is connected to mainland Sri Lanka by both road and railway bridges.
Cultural and Mythological Significance
Ram Setu holds significant cultural and mythological importance in India and Sri Lanka. Originally named Nala Setu after its architect Nala,
