Eyeing the Milky Way, a new ‘little black hole’ discovered near space

In early 2022, a team of astronomers from the Space Telescope Science Institute revealed that black hole Stellar mass wanders alone in Milky Way.

Many black holes in the Milky Way

Experts from the Institute in Baltimore, Maryland detail Black hole may be one of the 100 million black holes in space and the smallest ever discoveredbased on an estimate of its mass.

Kailash Sahu, head of the institute, revealed that the black hole is 5,000 light-years away and is considered to be gravitationally lensed, that is, it magnifies the background starlight to 19,000 light-years away .

According to the Space Portal, the discovery was first made through two ground-based surveys: the Observational Microlensing for Astrophysics (MOA) project and the Optical Gravitational Lensing Experiment (OGLE) at Mount John University Observatory in New Zealand, based in Poland headed by.

To accomplish this feat, Sahu’s team used Hubble Space Telescopeknown for capturing stunning images of tracks.

In this study, following a degree of gravitational lensing, it was seen that the black hole was 7.1 times the mass of the sun.

A second team, led by Casey of the University of California, identified a different volume in which the artifact was between 1.6 and 4.4 times the mass of the Sun.

Stellar-mass black holes are the product of so-called supernovae

exist Supernovastars that ended their lives and exploded brilliantly in space originated from black holes 20 times more massive than the sun.

Supernova will eventually stay Neutron star, its mass is on average 2.3 times that of the Sun. It has been determined that stellar-mass black holes found in binary star systems do not appear below 5 times the mass of the sun.

“Whatever it is, this object is the first dark star remnant to wander the Milky Way without the company of another star,” Lin explained in a NASA statement.

While stars over 20 solar masses make up only 0.1% of all samples of the Milky Way, there are an average of 10 to 200 billion stars there.

Since our Milky Way has been around for more than 13 billion years, it probably has an average of 100 million or more stellar-mass black holes “around us”.

However, such a discovery is only the beginning of the vast amount of information contained in the Milky Way.Prediction is NASA’s Roman Nancy Grace Space Telescope To be released in 2027 to analyze more events involving black holes.
