This photograph shows the region of the sky, in the constellation of Telescopium, where HR 6819 can be found, a triple system consisting of two stars and the closest black hole to Earth ever found.
© And as we know, you can’t go faster than the speed of light. An international team of astronomers says that they’ve discovered the closest black hole to Earth — an invisible object dancing with two large, bright stars 1,000 light-years away. Our journalists strive for accuracy but on occasion we make mistakes. Mind-blowing ‘world first’ images of a black hole spewing out plasma 5billion light-years away were revealed last year. However, it … See no ads on this site, see our videos early, special bonus material, and much more.

Recent studies offer evidence for and against the idea. 11,000 light-years away (perhaps much closer). The supermassive ones are relatively straightforward.
said study team member Peter Jonker of SRON NetherlandsInstitute for Space Research.
The Orionid meteor shower peaks this week! But there could still be others lurking even closer that have yet to be detected; astronomers estimate that there are millions of black holes in our galaxy alone. I’m sorry to say but I think a lot of people that read this article are going to go away with wrong ideas about what black holes are like and what they can do. In 2015, NASA's Swift X-ray space telescope caught "light" echoes during an eruption that sent X-rays reflecting off the rings of dust that surround the system. Scientists found evidence of the invisible object by tracking its two companion stars using a telescope at ESO's La Silla Observatory in Chile. Study leader and ESO scientist Dr Thomas Rivinius said: "This system contains the nearest black hole to Earth that we know of. Only a black hole could make its binary partner buzz around so quickly.

The black hole is not "lurking". By observing the system for several months, they were able to map out the stars' orbits and figure out that another massive, unseen object must be acting in the system.

Sorry but that’s utter nonsense. It forms part of a 'triple system' with its two accompanying stars (artist impression), Black holes are mysterious phenomena that suck in everything around them - even light, The first-ever image of a black hole was released by scientists last year, Independent Press Standards Organisation (IPSO), A black hole is a region of space where absolutely nothing can escape, That's because they have extremely strong gravitational effects, which means once something goes into a black hole, it can't come back out, They get their name because even light can't escape once it's been sucked in – which is why a black hole is completely dark, There has to be a point at which you're so close to a black hole you can't escape, Otherwise literally everything in the universe would have been sucked into one, The point at which you can no longer escape from a black hole's gravitational pull is called the event horizon, The event horizon varies between different black holes, depending on their mass and size, The gravitational singularity is the very centre of a black hole, It's a one-dimensional point that contains an incredibly large mass in an infinitely small space, At the singularity, space-time curves infinitely and the gravitational pull is infinitely strong, Conventional laws of physics stop applying at this point, Most black holes are made when a supergiant star dies, This happens when stars run out of fuel – like hydrogen – to burn, causing the star to collapse, When this happens, gravity pulls the centre of the star inwards quickly, and collapses into a tiny ball, It expands and contracts until one final collapse, causing part of the star to collapse inward thanks to gravity, and the rest of the star to explode outwards, The remaining central ball is extremely dense, and if it's especially dense, you get a black hole.

In the past century, not only have astronomers shown that black holes do exist, but they’ve found dozens in our own galaxy.
Bigger stars within BH mass range inevitably did get close during the previous billions of years. The researchersdetermined that the black hole V404 Cygni is located 7,800 light-years fromEarth ? The rest are stellar black holes that are never heavier than 15 times our Sun.
What Would Happen if You Fell Into a Black Hole? The team originally observed the system, called HR 6819, as part of a study of double-star systems. We pay for your stories!

It makes sense to keep track of all the black holes out there, just in case we might need to evacuate this Solar System in a hurry.
And astronomers believe the revelation could shine some light on a second system called LB-1 which may also be a triple.
The previous closest black hole is probably about three times further, about 3,200 light-years, he said. Astronomers have spotted only a couple of dozen black holes in our galaxy to date, nearly all of which strongly interact with their environment and make their presence known by releasing powerful X-rays. There’s one at the heart of pretty much every single galaxy in the Universe. The researchersdetermined that the black hole V404 Cygni is located 7,800 light-years fromEarth ?
After HR 6819's black hole, the nearest known black hole is about 3,000 light-years away from Earth in the constellation Monoceros.

"An invisible object with a mass at least four times that of the sun can only be a black hole," Thomas Rivinius, a scientist with the European Southern Observatory who led the new study, said in a statement.

Research co-author Petr Hadrava, from the Academy of Sciences of the Czech Republic in Prague, said: "We were totally surprised when we realised that this is the first stellar system with a black hole that can be seen with the unaided eye.".

Nasa has revealed some of its plans for colonising the Moon. This wide-field view shows the region of the sky, in the constellation of Telescopium, where HR 6819 is located. They calculated that the object is a stellar-mass black hole — a black hole that forms from the collapse of a dying star — that's about four times the mass of the sun.
