Astronomy

Perfect timing, as just this past week I've been wondering about these low-frequency gravitational waves that were announced with a splash last summer, then I heard nothing, that is until now.

It takes a while to go through the data and find specific parameters you're looking for. This is radio astronomy, using data from antenna telescopes all over the world. For comparison in a similar type of project, it took two years to crunch the numbers from the Event Horizon Telescope and resolve a fuzzy image of the supermassive black hole in M87.
