An interesting idea - from The Guardian:
Two suns? No, it's a supernova drawn 6,000 years ago, say scientists
For decades, stone carvings unearthed in the Himalayan territory of Kashmir were thought to depict a hunting scene. But the presence of two celestial objects in the drawings has piqued the interest of a group of Indian astronomers.
They have proposed another theory. According to a study published in the Indian Journal of History of Science, the Kashmir rock drawings may be the oldest depiction of a supernova, the final explosion of a dying star, ever discovered.
Archaeologists found the carvings nearly half a century ago in Kashmir’s Burzahama site, where the oldest settlements have been dated to about 4,300BC. It showed two hunters, a bull, and two beaming disks in the sky initially speculated to be two suns.
Previously, the oldest supernova recorded was by Chinese astonomers in 800BC - this new discovery moves the goalposts quite a distance.
