Astronomers for years thought the galaxy SDSS1335+0728 was about as remarkable as its serial code name.
Then it did something scientists had never seen a galaxy do: Suddenly, this frankly forgettable space neighborhood 300 million light-years away threw the lights on. That happened nearly five years ago, and it's only gotten brighter since.
