covering the week's top textbooks like Linux bias astronomers have stumbled across the nearest black hole to us yet the void lies at the heart of a stellar system just a thousand light-years away and indications to his location are visible to the naked eye a team of researchers were observing the hr6 8 1 9 star system from the European Southern Observatory in Chile as part of a wider survey studying by our start binary star systems and they stumbled across a third object spectral graphic data revealed that one of the stars orbited an invisible companion every 40 days meanwhile the second star sits much farther away from the first they now believe that the HR 68 19 is not a double system but a triple system one that contains two stars that are both around the 6 solar masses and a third object that is at least 4.2 solar masses that number is much too high for the object to be a neutron star Thomas Ravinia spher star of the study said an invisible object with a mass at least four times out of the Sun can only be a black hole if the researchers are indeed correct the object will be the closest black hole from earth discovered yet Peter had drama the co-author of the research said the team was totally surprised when we realised that this is the first stellar system with a black hole that can be seen with the unaided eye as a point of clarity the black hole itself isn't visible to the naked eye only the stars are for those in the southern hemisphere hoping to catch a glimpse it's located in the telescope ium constellation and will be best viewed during a clear night and two fuzzy bright pinpricks should be discernible without binoculars or a telescope although the object seems to have been ears all along it is escape detection until now not only as a black hole pretty small is also very quiet meaning it doesn't spew Jets of electromagnetic radiation unlike the supermassive ones at the Centers of galaxies guzzling up the stars the team has only managed to infer its existence from the wobble of the stars that orbited the team is hoping to capture images of the orbit to further establish the distance and mass of the system's objects [Music]
