Italian astronaut Paolo Nespoli, on Thursday, photographed the Indian subcontinent from the International Space Station.
The 60-year-old captioned the picture, "Diwali, the Hindu Festival of Lights, starts today. #HappyDiwali to everyone!".
Twitter users reacted saying "Thank you for sharing a real picture", while some debated if the orange line represented the India-Pakistan border.
Since being shared online just three days ago, the picture has collected almost 6,000 'likes' and over 3,500 'retweets'.
