A huge pink heart-shaped structure has recently been sighted by NASA’s astronauts on the International Space Station (ISS). This giant heart covers an area close to 10 kilometres and is located in Argentina. Although this image looks extremely romantic, the pink heart-shaped structure is the result of a natural occurrence and not symbolic at all. Remote sensing and satellite imaging techniques have proved quite helpful in the identification of the pink heart in Argentina, which is formed due to the presence of salt lakes, algae blooms, and colorful water bodies rich in minerals.
