One supernova surprised astronomers: as it flared up, it changed its 'passport' type. It turns out there's no need to invent different kinds—it's all about the temperature of the outburst. Now, knowing this, we better understand how the 'stellar engines' at the center of such explosions work. This is another step toward unraveling the final days of massive stars.
🎯 One such supernova can outshine an entire galaxy, shining brighter than a hundred billion suns.
