The LIGO-Virgo-KAGRA network has extended its 4th observing run, and since late January 2025 has been in the third part of this observing run, called O4c. This final part of the observing run will conclude in October 2025, at which point there will be a commissioning break before starting the 5th observing run. New glitches (and hopefully new gravitational-wave events) inbound!
To learn more about gravitational-wave detectors and data analysis, we recommend the resources from the Gravitational Wave Open Science Center. The workshops are excellent for those who want to gain an in-depth understanding.
