New Delhi: The LIGO and Virgo gravitational wave observatories have detected a merger between two compact objects designated as S251112cm on 11 December 2025. Most of these mergers are between black holes or neutron stars, which are the dead cores of massive stars. Most of these objects contain between five and 200 solar masses, and are extremely compact. The new detection is exciting to scientists because one of the two objects in the merger appears to be less massive than the Sun. Such an object has never been observed before, but scientists have a few theories on what it could be.

Oo! Interesting #GravitationalWave candidate #S251112cm potentially from a *subsolar* mass source If real, the source is probably has chirp mass ~0.1–0.87 solar masses False alarm rate 1 in 6.2 yr
