Closer inspection, including with NASA's infrared space telescope NEOWISE, revealed that the dying star had swallowed a gas giant of similar size to Jupiter that had been orbiting around it. The final, bright explosion De witnessed in the night sky images took place in the final ten days of the planet's life as it became entirely subsumed into the red giant.
