Rock art in India gives oldest record of exploding star
Indian scientists have discovered a 5,000-year-old rock art in Kashmir, possibly the oldest human record of a supernova, a stellar explosion. The carving depicts a sky with two bright objects and a hunting scene. Researchers noted a supernova HB9 had exploded around 4600 BC and said the drawings might be representations of the event showing constellations Orion, Pisces, and Taurus.
