Scientists at Laser Interferometer Gravitational-Wave Observatory, LIGO in 2015 reported an observation of gravitational waves that shows the cosmic shockwave of two black holes fusing. In the same vein, in April 2019, Scientists from the same institute made another unusual “first” observation – another gravitational wave. However, this time around, the waves came out of a black hole while consuming a neutron star.
Interestingly, LIGO has observed five different cosmic mergers in April alone, including the one involving the neutron star. Rather than prompting uncertainties, this events has offered scientists relevant information that will improve their understanding of the dynamism of the universe.
LIGO has ultimately improved on his 2016 resolutions, particularly by working together with other observatories. With these upgrades, it is now easier to discover black hole mergers. Considering this, LIGO may stop publishing articles about each of these mergers, according to ARS.
While all these merger discoveries are not particularly exciting anymore, the same cannot be said of a black hole devouring a neutron. This is very unusual, and from the combined findings of these collaborating observatories, this phenomenon occurred about 1.2 billion light-years away. This means that the event can be dated far back as a billion years ago.
Scientists are still looking to discover the precise location of the merger with respect to the night sky. However, reports from ARS indicates that the region currently under observation has been reduced significantly to just 3% of the sky. What this means is that it is only a matter of time before the observatories spot a visual component of the merger (if any).
