Astronomers have recently found a supermassive black hole in the center of our galaxy. Sagittarius A was the first black hole to be captured on camera. The twin detectors “LIGO” from the US and “Virgo” from Italy have picked up gravitational waves which are usually found when two massive solar bodies collide.
LIGO stands for Laser Interferometer Gravitational-Wave Observatory. It is a large-scale observatory used to detect cosmic gravitational waves. It is useful to deduce observations and is widely used as a gravitational tool.
A representative from the NSF has informed us that they have invested over $1 billion in the construction and operation of the LIGO detectors. The NSF, National Science Foundation, is a federal agency that supports the majority of land-based observatories, while NASA primarily supports space-based observatories.
Scientists believe that it may have come from the same black hole consuming a neutron star, but they aren’t sure if the star shattered before crossing the black hole’s domain or was devoured in one piece. It depends on the size of the black hole.
The black hole image
The first image of a black hole was also funded by the NSF, captured with the help of their Event Horizon Telescope (EHT).

A neutron star that collides with a larger black hole may dissolve inside it, but a smaller black hole can tear the neutron star into bits and then consume it. A neutron star is the collapsed core of a normal star.
They are one of the smallest and most dense stars discovered so far. They have a radius of 10 kilometers (6.2 miles) and their mass is lower than 2.16 solar masses. The star is constructed entirely of neutrons.
They have a density of 3.7×1017 to 5.9×1017 kg/m3 which is more dense than the sun. It is so dense that even one teaspoon of it’s matter would weigh about 900 times the Pyramid of Giza!
