For centuries, the primary way that astronomers studied outer space was through sight. But just ten years ago, scientists successfully established a way to 'listen' to our cosmos – detecting ...

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by international pulsar timing array collaborations in 2023 could come from a stochastic ...

Ten years ago, astronomers made an epic discovery with the Laser Interferometer Gravitational-Wave Observatory. Cosmology hasn’t been the same since, and it might not stay that way much longer. Out ...

The international LIGO-Virgo-KAGRA Collaboration reports the observations of two record-breaking events in gravitational wave ...

Stephen Hawking’s 50-year-old theorem on how black holes merge together has been successfully tested thanks to huge advances in gravitational wave astronomy, which helped astronomers catch the waves ...

Powerful, twisting lasers could let us create and detect gravitational waves, the ripples in space-time thus far only seen coming from cosmic objects. While the technology to do so is decades away, ...

On Thursday, the European Space Agency’s Science Programme Committee gave the go-ahead to the Laser Interferometer Space Antenna, or LISA project. This would mean the construction of the mission’s ...

There’s a big debate in cosmology about how fast the universe is currently expanding. The collision of two neutron stars in 2017, seen in an artist's rendering, created both gravitational waves and ...
