A PREHISTORIC rock carving could be the earliest ever depiction of a supernova, scientists claim.
The ancient artwork shows a hunter spearing a deer while another aims a bow and arrow under two bright objects in the sky and what looks like a dog also stands nearby.
Now archaeologists studying the carving found in the Burzahama region of the northern Indian state of Jammu and Kashmirin in the 1960s say the bright objects depict the moon and a supernova that would have appeared in the night sky around 3,600 BC.
They say the celestial objects on the 10.6 inch by 18.9 inch slab are unlikely to be the sun and moon as previously thought, as the moon would not be visible if it were so close to the sun. A star chart is seen behind the scene.
The carving is thought to date from some time between 2100 and 4100BC and astronomers know a supernova called HB9 was visible in around 3600BC.
