Black hole discovery opens doorsteps for new Research ‘Skies belong to US’

Scientist stunned to say GIANT BLACK HOLE ‘SHOULD NOT EVEN EXIST’ 

Researchers have discovered a black hole 1,000 light-years from Earth, the closest one known so far. The Milky Way galaxy has number of black holes, but this discovery which is 1,000 light-years away from our planet suggests there could be many more which are yet to be discovered. A light-year is equal to 6 trillion miles from planet earth and a unit which measures distance in space.

Rivinius-Science Operations Support Astronomer-added, “There must be hundreds of millions of black holes out there, but we know about only very few. If we know what we are looking for, it put us in a better position to find them”.

Dubbed HR 6819, the is invisible. The star system was only spotted after two companion stars provided researchers with information on its whereabouts. Without the use of a binocular or telescope, this black hole can be seen on a clear night in the Southern Hemisphere making it the first black hole to be seen without tools.

Petr Hadrava’ who is one of the study’s co-authors at Emeritus Scientist at the Academy of Sciences of the Czech Republic in a statement said, “We were totally surprised to know that this is the first stellar system with a black hole that can be seen with the naked eye”.

French astronomer Nicolas-Louis de Lacaille discovered this star system which is located in the Telescopium constellation in 1751–52.

The researchers used MPG/ESO 2.2-meter telescope to look at the star system, they found that one of the stars was orbiting the black hole every 40 days. This telescope is mounted at European Southern Observatory’s La Silla Observatory in Chile.

Another co-author of the research group Mr. Dietrich Baade said, “The observations needed to determine the period of 40 days had to be spread over several months.” ESO’s pioneering service-observing scheme was used for this observation and research. ESO staff made this observations for the scientist for their research work.

As all black holes are invisible so does this one which itself is invisible and does not have violent interactions with objects around it.

Thomas Rivinius who is the lead author of the study concluded black hole identity as, “An invisible object with a mass at least 4 times that of the Sun can only be a black hole”.

Marianne Heida informed about another system of same category that’s under consideration is LB-1. It is expected this star system may also be a triple star system.

Heida who is the co-author of the study said in the statement “LB-1 is observed to be farther away from Earth but still pretty close in astronomical terms, with this discovery we can say probably many more of star systems like this one exist”.

We can learn a lot by finding and studying the formation and evolution of those rare stars. These stars begin their lives with more than about 8 times the mass of the Sun and end them in a supernova explosion that leaves behind a black hole.
