Neutron star merger generated illusion of superluminal jet

10 September 2018 Astronomy Now

The merger of two neutron stars, observed in August, created two powerful jets streaming away into space at nearly the speed of light, in agreement with theoretical predictions and shedding new light on gamma ray bursts.

Colliding neutron stars likely formed low-mass black hole

1 June 2018 Astronomy Now

Colliding neutron stars generated headlines last year after the detection of gravitational waves sweeping through the solar system. Follow-on X-ray observations indicate the cataclysmic merger formed a record low-mass black hole.

Neutron star merger yields new puzzle for astrophysicists

19 January 2018 Astronomy Now

The afterglow from the distant neutron star merger detected last August has continued to brighten — much to the surprise of astrophysicists studying the aftermath of the massive collision that took place about 138 million light-years away and sent gravitational waves rippling through the Universe.

First light detected from violent neutron star collision

16 October 2017 Astronomy Now

For the first time, scientists have detected light tied to a gravitational-wave event, thanks to two merging neutron stars in the galaxy NGC 4993, located about 130 million light-years from Earth in the constellation Hydra.
