STARSLAM ’17

Science!

FiveThirtyEight has a wonderful story about how August 17th was pretty much the biggest day in astronomy history.

On that day, astronomers bore witness to the titanic collision of two neutron stars, the densest things in the universe besides black holes. In the collision’s wake, astronomers answered multiple major questions that have dominated their field for a generation. They solved the origin of gamma-ray bursts, mysterious jets of hardcore radiation that could potentially roast Earth. They glimpsed the forging of heavy metals, like gold and platinum. They measured the rate at which the expansion of the universe is accelerating. They caught light at the same time as gravitational waves, confirmation that waves move at the speed of light.

That’s a big day!

Richard O’Shaughnessy, an astronomer at the Rochester Institute of Technology, describes the discovery as a “Rosetta stone for astronomy.” “What this has done is provide one event that unites all these different threads of astronomy at once,” he said. “Like, all our dreams have come true, and they came true now…”

“It’s a wonderful time, it’s a terrifying time,” O’Shaughnessy said. “I can’t really capture the wonder and the horror and glee and happiness.”

Coincidentally The Wonder and The Horror and Glee and Happiness would be what I’d call a barbershop quartet, if I were in one. Or they were still a thing.
