Gemini North Telescope on Hawaii reveals first dormant, stellar-mass black hole.
Astronomers have discovered the closest black hole to Earth, the first unambiguous detection of a dormant stellar-mass black hole in the Milky Way. Its close proximity to Earth, a mere 1,600 light-years away, offers an intriguing target of study to advance understanding of the evolution of binary systems.
The U.S. National Science Foundation provided funding support for the work. The astronomers used the Gemini North Telescope on Hawaii, operated by NSF’s NOIRLab, one of the twin telescopes of the International Gemini Observatory.
The discovery was made possible by making observations of the motion of the black hole’s companion, a sunlike star that orbits the black hole at about the same distance as the Earth orbits the sun. Though there are likely millions of stellar-mass black holes in the Milky Way galaxy, those few that have been detected were uncovered by their energetic interactions with a companion star. As material from a nearby star spirals in toward the black hole, it becomes superheated and generates powerful X-rays and jets of material. If a black hole is not actively feeding, it is dormant and not directly detectable.
This dormant black hole is about 10 times more massive than the sun and is located about 1,600 light-years away in the constellation Ophiuchus, making it three times closer to Earth than the previous record holder.
“Take the solar system, put a black hole where the sun is, and the sun where the Earth is, and you get this system,” explained Kareem El-Badry, an astrophysicist and lead author of a paper published in Monthly Notices of the Royal Astronomical Society.
The team relied not only on Gemini North’s superb observational capabilities but also on Gemini’s ability to provide data on a tight deadline, as the team had only a short window in which to perform their follow-up observations.
“As part of a network of space- and ground-based observatories, Gemini North has not only provided strong evidence for the nearest black hole to date but also the first pristine black hole system, uncluttered by the usual hot gas interacting with the black hole,” said NSF Gemini Program Officer Martin Still.

What are the chances of it swallowing earth? How do we know we are on the sucked in side or the already spit out side. I know they say the energy in it is massive. But any thing ever been through one to know what happens?may be there are paths off to the sides of the inside. Maybe it spits things out. Could the inside of one be a wrinkle in travel? Or worm hole?
Can anything in it go fast enough to not be shredded? Just wondering…
How dangerous is this to our solar system. Please projectits path0 to see if it is coming to us.
SO to Dennis O’Donnell’s question it 1600 light year away…the problem I have is it states “G dwarf Temp(eff) = 5850 K” and if I go by the star program Celestia, the star in orbit of this black hole is G0III…
Blackholes are everywhere. Even star sun can n have become ⚫ holes. No , to worry if, in the path of blackhole dust u will be. But there is the Enos of cooling effects that dust becomes a planet again. Deva daya whooo would know that……. intellectual blackhole n whitelight is a reflection. Bamamamama got to get ready for a grilling out . Ham chicken and porkchops n pizza 🥦 must feed like the ⚫ hole.
I think this black hole it’s a way to heaven.
So as depicted in that picture, is that silver ring a dormant black hole?
Ive had dreams of these things in the night sky. They were coming together and multiplying.
Started off as one that split apart into 2. Then the two came together. When they split off from eachother the two became 4. Then they came together and split off from one another,and became 6 and so on. This went on until as far as my eyes could see, there were ten. But this was only as far across the night sky that I could see! I knew there were more around the planet. Then about numbers coming out in a line going out into space. I woke up yelling out “it’s binary!” I have no idea why it what all of this meant!
These dormant black holes, If that’s what that silver ring thing in fact is, then I am especially intrigued about this. Because this means something exponential!
Do these things at all come out of their dormancy? Is that possible? If like to know based on an actual knowledge of it being possible or not. Not an educated guess. Just has this been known to happen or not? If so, do they potentially put Us in Earth at any risk?
I have believed that black holes create suns and since there is a bend in space time , newborn suns get spit out , much like when we get chicken pox or poison Ivey. Then the sun’s appear and other masses that make up our galaxies. I been thinkin of a lot of different ideas . also that our Universe has at least 1 fracture in it and probably at least 2.
So we see it at a point it was at 16,000years ago.Where is it now?
A huge col, and a water
y planet in it?
Every day we keep on getting new theories/hypothesis about the universe .Actually we dont know much about the black holes ,dark energy etc we even do not fully understand the atom what to talk about as to how they were formed.we may not like/accept it but
Most of these things are beyond human comprehension .God Almighty has given a limited knowledge to us humans but we are not readyto accept it. Only He has complete knowledge of everything. Leave aside the universe just look at our brain and body- how complex it is .The way brain communicates with the body and controls it through the complex system of nerves. Look at the eyes , ears, heart, lungs, stomach etc its nothing short of miracle.on top of it our DNA code is another miracle.The early we understand the plan, the design and power of our Maker the better it will be for us human beings.
Watched a little on black holes but I’m just learning what is written. I’m not a scientist or astronomer. Can we get clarification on what direction it’s travelling and how far away it is now? Countries are going to war with each other over their own issue of power whilst our earth is dying and now outside threats like meteor 2023DW comes and now this. These leaks can cause world wide panic I know this but let’s face some facts and start bringing unity and peace while we can.
