  • Astronomers have detected the second largest explosion in the universe after the Big Bang.
  • It happened 390 million light years from Earth, and was so powerful that you could “fit 15 Milky Way galaxies” into the cosmic hole that it created.
  • Four radio telescopes in different locations across the Earth were necessary to uncover this, and it’s compared to the discovery of the first dinosaur bones.
  • The telescopes aren’t even at full capacity yet, and once they are, astronomers predict they’ll discover more cosmic events like this.
