Continued light from neutron-star merger confuses scientists
Contrary to expectations, the afterglow from the neutron-star merger detected in August 2017 has continued to brighten, a Canada-based study has found. Usually, gamma-ray bursts are seen for a short time, which then fade as the system stops releasing energy, said researchers. The gravitational-wave event was detected by LIGO and confirmed by its gamma-ray emission by over 70 telescopes worldwide.
