This Black Hole Is So Close You Can “See” It, Here’s How

A team of astronomers discovered a black hole lying just 1,000 light-years from Earth — and its presence may hint at the existence of many more.

Astronomers have just found the closest black hole to us yet, a discovery which suggests there could be even more black holes lurking out there in the universe.

The astronomers were originally looking for a double star system called HR 6819 — a pair of stars close enough that it can be seen from the Southern Hemisphere without any optical aids on a dark and clear night. But while observing the stars, the astronomers realized that what they were really seeing was a three body system: The inner star was orbiting around something (hint, hint: a black hole) once every 40 days, while the outer star orbited the pair from much farther away.

So how did researchers know that the star was orbiting a black hole? And what does this discovery mean for the future of space observation and our understanding of large stars and three body systems? Find out in this Elements.

10 Questions You Might Have About Black Holes

“While black holes are mysterious and exotic, they are also a key consequence of how gravity works: When a lot of mass gets compressed into a small enough space, the resulting object rips the very fabric of space and time, becoming what is called a singularity.”

Closest black hole to Earth found ‘hiding in plain sight’

“The astronomers studying HR 6819 weren’t looking for black holes at all. Instead, they wanted to learn more about a pair of odd stars orbiting each other.”

How Supermassive Black Holes Were Discovered

“Given that the centers of galaxies might harbor supermassive black holes, it was natural to check the center of our Milky Way galaxy for such a monster. In 1974, a very compact radio source, smaller than 1 second of arc (1/3600 of a degree) was discovered there.”

    Black Holes give me anxiety because it doesn't make sense.
    Some people find comfort saying you become energy after death. The black hole is the death of everything. To me they embody "hell".

    just read a physicist say that all physicists know that there is no such thing as black holes.. because of the time dilation… it would require infinite time to actually produce a black hole….. so, who knows.

    If we didn't know about millions of black hols existing, won't they account for that 85% source of gravity that we know as dark matter??

    I was about to ask: Will this explain dark matter or dark energy? But then I realized: Oops, no wait, quite the opposite, because dark energy has an anti-gravity effect!! So does this discovery make what we know about gravity even more uncertain? 😂

    They’re not black holes. They’re actually stars like our sun that have grown so massive the light they create and the light that comes near them gets sucked inside and trapped, because it’s so so so so big. It appears black because no light can reflect from it or shine from it, but it is a star. It’s a very massive and small star, I bet it’s beautiful and if someday we can get passed the event horizon we will see it.

    my only real question is, how many black holes do they "NOT" account for when they say we are missing X percentage of baryonic matter in their galactic orbit calculations.

    Theologically speaking, if you want some interesting religious/historical context on black holes, they are described in pretty interesting detail in the Book of Enoch. Enoch is said to have been just the 7th man created from Adam on earth, so we are certainly going back about as far as we can…at least in this age, in terms of our "knowledge" of their existence. Enoch was supposedly taken on a "journey" through the "heavens" (a sort of "guided tour" if you will) by an Archangel. One of the things he physically describes seeing is an exact description of the modern day definition of black holes. He is so intrigued and fascinated by the sight of them, that he inquires as to what they are. The Archangel then goes on to describe them as the "prison places of the fallen ones who are held in chains until the Judgement." This is extremely interesting AND extremely accurate being that we now KNOW that nothing, not EVEN LIGHT, can escape a black hole.
    It ALSO say's that one day those "fallen ones" will be "loosed" from their chains to wreak havoc upon the earth, but we aren't given specifics as to exactly when that will be…nor did Enoch really even have the language tools to describe what he was witnessing since scientific knowledge between humans hadn't advanced to the point yet where we even had the words to describe what Enoch actually saw and experienced. We in fact COULDN'T understand or "unlock" what any of this even meant until fairly recently upon the scientific community's increased abilities to explore and understand better what is happening out there in "space." We can at least gather that whatever is "yet" to happen with these "black holes" as far as prophecy goes, it's going to have a pretty catastrophic effect considering that Enoch describes it by saying that the "heavens will recede like a scroll" which of course, sounds….interesting. AND fairly catastrophic.
