Unicorn: The Closest Known Black Hole To Earth

What you're looking at is the so-called “Monoceros” (“The unicorn”) constellation. Monoceros is a faint constellation on the celestial equator.  It is a unique constellation with unique features, and astronomers say it's not over.  Because they have found evidence for a candidate black hole that resides in this constellation.  And they dubbed it “The unicorn”.  Follow me on this video to get to know more about the fantastic world of Black holes and...unicorns!

It is one of the closest black holes to Earth, at a distance of 1500 light-years.  I know what you're wondering: why “The unicorn”? Well, the nickname seems to have a double meaning: not only does the black hole candidate lie in Monoceros, but also its incredibly low mass – about three times that of the sun – makes it nearly one of a kind. "Because the system is so unique and so weird, you know, it definitely warranted the nickname of 'The Unicorn,'" discovery team leader Tharindu Jayasinghe, an astronomy PhD student at The Ohio State University, said in a new video the school made to explain the find. By the way, we said the black hole weighs 3 solar masses. How much is “three solar masses”? Let's do some calculations. The Sun's mass is about 1.98*10^30 Kg, which is to say that this “small” black hole weighs about 6*10^30 Kg.  Just for a term of comparison, let's consider some other well-known black holes.  For example, the famous M87 Blackhole – the one black hole that spread all over the world thanks to the beautiful pic astronomers took - is about 6.5 billion suns. It's huge.  Another famous black hole is the one at the centre of our Milky Way, Sagittarius A*, and it has a mass of about 4 million solar masses.  In this sense, we say “The unicorn” it's a tiny and peculiar black hole. Very few such super-lightweight black holes are known because they're incredibly hard to find.  Black holes famously gobble up everything, including light, so astronomers have traditionally detected them by noticing the impact they have on near objects. In fact, black holes are...black! And we can find them only considering the impact they have on their surroundings (mostly stars). At this point it should be clear that we can't directly observe a black hole, which could lead to the question: so how did astronomers find the evidence for “the unicorn” in the Monoceros constellation? What were they looking at? Which instruments did they use to detect it? Most of the time in the universe we find objects that are gravitationally connected.  Binary systems of stars, star systems like the solar system, pulsars that have started a merging process, cannibal black holes, and so on.  Even the moon and the Earth are, of course, gravitationally connected.  Connection.  This is how astronomers found our unicorn black hole.  Astronomers led by Tharindu Jayasinghe, a doctoral student and presidential fellow at The Ohio State University, were searching for bright stars accompanied by “non-interacting” black holes, which are black holes that aren’t tugging material off their stellar companions when they suddenly saw signs of the Unicorn around a red giant star in Monoceros.  Jayasinghe and his colleagues spotted just this type of gravitational influence, known as a tidal distortion, affecting a bright dying star called V723 Mon. This hint prompted the team to search for the signs of the star’s potential companion, which had to be both much less luminous and significantly more massive than the giant, V723 Mon. - "If You happen to see any content that is yours, and we didn't give credit in the right manner please let us know at Lorenzovareseaziendale@gmail.com and we will correct it immediately" "Some of our visual content is under an Attribution-ShareAlike license.
