Something strange is happening 820,000 light years from Earth.
This region, which is very close in cosmic terms, appears to contain a small dwarf galaxie called Leo I that contains a supermassive dark hole that has been flying by. under the radar for years. This semi-hidden gap is SoGiant, responsible to incredible amounts of gravitational force and boasting a mass 3 million times greater than the Sun, which is something you wouldn’t expect to find on such a small planet.
This is unfortunately the truth.
It is aptly called Leo I * – and according to The paper was published on MondayAstrophysical Journal Letters features two scientists who are trying to figure out how this unusually large and difficult-to-detect hole formed.
In their study, astrophysicists Fabio Paccucci and Avi Loeb of the Harvard-Smithsonian Center for Astrophysics describe a fascinating way to analyze Leo I* so we can dissect some of its background. Basically, they think it is possible to understand the nature of Leo I* by studying the space around this black hole where a lot of ancient stars seem to reside and potentially get caught in the monster’s adorable gravitational embrace.
“Old stars get very big and red — we call them red giant stars,” Bacucci said he said in a statement. “Red giants have strong winds that carry only a fraction (or none) of their mass into our environment. The space around Leo I* seems to have enough of these ancient stars to make them observable.”
“Lion Watch I * can be groundbreaking,” Loeb said in a statement.
That’s because, in addition to its enigmatic location in the Leo I galaxy, Leo I* is also the second closest supermassive black hole to Earth, after the one at the heart of our Milky Way galaxy named arch a*. (This is what the scholars void. Pictures last yearThis is an amazing landmark in astronomy.
Leo I* oddly also has a similar mass to Sgr A* although, again, it lives in a disproportionately small galaxy – a thousand times less than Sgr A*’s home.
Loeb stated, “This fact challenges everything that we know about the evolution of galaxies and supermassive black hole systems together.”
The skeleton and the core of a black hole
With such an impressive list of traits, you might be wondering, why haven’t scientists directly observed Leo I* before?
This black hole is very difficult to capture, but there is a caveat. Before we get into the details, let’s first give you a brief overview. Anatomy of a black hole.
Black holes can be viewed from three perspectives: the singularity and the event horizon.
Black holes are extremely dense areas of matter that are embedded in the fabric of time and space. They exhibit strong gravitational pulls. Just one of those can take a bunch of stars, planets, space-borne dust, moons—anything you can think of, including light—and levitate them all into one point. This point is known as the singularity. It is located at center of the black holes.
Next is the event horizon.
The black hole’s singularity is the event horizon. You can think of it as a fence through the which light cannot escape. The Schwarzschild radius is the distance at which the event horizon lies.
The growth disc is last.
An accretion disc is a disk-like structure that is further away from the singularity than at the event horizon but close enough to feel the monster’s gravitational force. This thing looks like a circular trench made up of dust, gas, or other cosmic material that is trapped by the black hole’s suction.
The accretion disk, more importantly, is key to understanding the universe’s largest, deepest, and darkest black hole.
She hid in her finger
Bacucci stated that black holes can be very mysterious and they sometimes enjoy playing hide and seek. “Rays of light cannot escape their event horizons, but the environment around them can be very bright — if enough matter falls into their gravitational well.”
Also, black holes can be easily traced for their accumulation of dust and gas.
In fact, peering into the accretion disks and event horizon boundaries of both SgrA* and M87* is how scientists created the world’s first free-to-fire donut images to begin with. But as you might have guessed by now, Leo I* is NotOne of those voids you can easily see.
Bacucci explains that a black hole doesn’t accumulate mass. Instead, it emits no light, making it impossible to locate with our telescopes.
However, if the astrophysical duo are right that the red giants around Leo I* give off enough material to be trapped in a vacuum accretion disk, then perhaps there is some hope. Paccucci explained that “in our study, we suggested a small amount mass lost from stars orbiting black holes could provide the required accretion rate to observe it.” “Leo I* plays hide and seek, but emits so much radiation that it goes undetected for a long time.”
Researchers are also welcome Draw attention to how Leo I*Its existence was first demonstrated by the observation of its accretion disc and nearby stars being accelerated due to the black hole’s intense gravitational force.
And while Pacucci and Loeb don’t think we’ll get an amazing image of Leo I* quite like we have of SgrA* and M87*, the team has already blocked some time at the Chandra X-Ray Observatory and Very Large Array Radio Telescope in New Mexico to follow up their idea.
Loeb said, “This is exciting, since science usually advances most when the unexpected happens.”
After all, before we got an image of Sgr A*, its stark location in the heart of our Milky Way galaxy was deemed nearly impossible to see.
Then, against all odds, we noticed it — and astronomy was changed forever.
