Sometimes, when you wait long enough, a story that you never thought would happen actually does materialize. I’ve written before about the decades-long search to find gravitational waves. So I was thrilled a few weeks ago to be able to cover the story of the first direct detection of these ripples in spacetime. Ahead of time we’d gotten notice of a big media announcement from the LIGO team, to be held at the National Press Club in Washington DC. I flew in from Colorado, my colleague Davide Castelvecchi flew in from London, and together we wrote a package of stories explaining what was discovered, how it was discovered, why it’s important, and how the next generation of astrophysicists will take things from here.
