'It's Just Too Perfect': Inside the First Gravitiational Wave Detection

Astronomy Magazine - Wed, 09/14/2016 - 04:00
A year ago today, a select group of scientists became the first people on the planet to learn that, after a century of theory and experiments, Albert Einstein was right all along. Researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) in Livingston, Louisiana had, at last, detected a gravitational wave. The ripple in space-time — a “chirp in the data — emanated from the merger of two black holes that collided some 1.3 billion years ago. This ripple in th

Can the moon make an earthquake worse?

Astronomy Magazine - Wed, 09/14/2016 - 04:00
When an earthquake occurs, it represents the release of years, sometimes decades or centuries, of pent-up stress. Somewhere along the fault line, a section of rock can take the strain no longer and gives way, allowing a tectonic plate to jerk into motion in a series of spasmodic shudders. The factors that determine when, where and why earthquakes happen are numerous, and we’re still a long way from figuring out how to reliably predict them. But, it turns out that one of the many small str
