“I turn my telescope to Barnards Loop and M42, glowing in Orions sword. Stars are fires that burn for thousands of years. Some of them burn slow and long, like red dwarfs. Others-blue giants-burn their due so fast they shine across great distances, and are easy to see.As they Starr to run out of fuel,they burn helium, grow even hotter, and explode in a supernova. Supernovas, they're brighter than the brightest galaxies. They die, but everyone watches them go.”
