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.”
The American physicists Rainer Weiss, Kip Thorne and Barry Barish were honored for dreaming up and realizing the experiment that confirmed the existence of gravitational waves.
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.
The Advanced Laser Interferometer Gravitational-Wave Observatory’s third detection further compounds the mystery of why black holes collide.
For decades, researchers believed that violent supernovas forged gold and other heavy elements. But many now argue for a different cosmic quarry.
How do scientists react to major breaking science news? For astrophysicists after the big gravitational waves announcement, it was meeting for two weeks in Santa Barbara, California.
Just months after their discovery, gravitational waves coming from the mergers of black holes are shaking up astrophysics.
The physicist Asimina Arvanitaki is thinking up ways to search gravitational wave data for evidence of dark matter particles orbiting black holes.
