What's up in
Astronomers have for the first time matched a gravitational-wave signal to a kilonova’s burst of light, observations that will “go down in the history of astronomy.”
Even as the solar eclipse was mesmerizing millions, astronomers were training their space- and land-based telescopes on a far more violent astrophysical event.
The team that discovered gravitational waves put their data online. Now an independent group of researchers claims that they’ve found what might be a serious problem.
