Scientists marvel at collision between black hole and possible neutron star

Scientists discover neutron star was swallowed by black hole Black Hole Swallowing a Neutron Star Detected

"We have always thought that there should be binary systems of a black hole and a neutron star circling each other out in space, so if this event is confirmed, it would be the first evidence that such systems do actually exist, and that some of them are spiraling closer and closer and eventually smashing together", Scott said.

Scientists observing the black hole for four days in April and May of this year using the Keck II Telescope in Hawaii saw the event.

Gravitational waves were predicted by Albert Einstein in 1916 as part of his general theory of relativity.

Mr Do, an astronomer at UCLA, wrote: "Here's a timelapse of images over 2.5 hr from May from @keckobservatory of the supermassive black hole Sgr A*".

Researchers are now tirelessly scanning the sky, searching for the light that may have been left behind by the neutron star as it was absorbed into the black hole.

This is the last type of gravity wave collision scientists have been looking for, having already seen several signals from pairs of black holes and neutron stars.

"Strange Glow" -Neutron Stars or Dark Matter Source of Odd Light At Milky Way's Center? Scientists observed the event at both the advanced LIGO (Laser Interferometer Gravitational-Wave Observatory) and Virgo, LIGO's Italian counterpart.

A black hole swallowing a neutron star has been detected for the first time, according to global space scientists. Until the final results are published in peer-reviewed scientific journals, take them with a pinch of salt - however, preliminary data suggests it's highly that what we're seeing is a black hole enveloping a neutron star.

Wheeler later tweeted that, after preparing for the worst, he was relieved "no lives were lost" and weapons were quickly seized. The Portland Bureau of Transportation's 1st Avenue and Jefferson Street SmartPark garage will also be closed all day Saturday.

If confirmed, it would be the first time gravitational waves from such an event have been detected. "It's much more likely to turn up a real one, so that means it's worth investing more time and effort".

Nevertheless, Scott notes there is a small chance that the gravitational waves were generated by an even more exotic phenomenon-the black hole swallowing a very light black hole. The larger of the two objects is well within black hole territory, but the smaller one is a bit south of three solar masses.

If they are right, the latest detection would complete a trifecta for the scientists.

This leaves an extremely dense object known as a neutron star, which squashes more mass than is contained in the sun into the size of a city.

"We are not aware of any black holes in the universe with masses less than about five solar masses", Scott said. And now, we might have stumbled upon a merger of these two.

The discovery was revealed on Saturday by NASA astronomer Tuan Do who tweeted a timelapse of his observation of the supermassive black hole in May. Weeks of study and the observation of the subtle features of the gravitational waves could indicate the true nature of the speculated neutron star.

The next step is focusing the telescopes on the area where the event happened.
