Recently a mysterious object redefined everything we thought we knew about black holes. First of all black holes are supposed to suck everything into them, even light. Secondly, the gravity is so strong that it was believed that nothing in the known universe could come out of a black hole.
That all changed when NASA announced that something very large exited a black hole.
So what exactly happened? Well as two of NASA’s space telescopes, which included the Nuclear Spectroscopic Telescope Array or (NuSTAR) for short, were observing this particular black hole, a large object very suddenly “launched” itself away from the middle or “corona” of the black hole. Right after this remarkable event a massive pulse of X-ray energy spewed forth from the corona. This event seems to have the scientists of earth completely baffled.
To Fiona Harrison, who is the principal investigator for NuSTAR, made a strong note saying that this type of phenomenon is unheard of and completely changes what we originally thought about how black holes function. Luckily with the level of technology that we as a race have been able to achieve, we were able to record this event. The data from this should provide now, some much-needed clues to just how black holes function and how they are structured.
Saint Mary’s universities, Dan Wilkins says that,
“This is the first time we have been able to link the launching of the corona to a flare. “This will help us understand how supermassive black holes power some of the brightest objects in the universe.”
The Milky way is immense, and in a region of our galaxy that is simply called Sagittarius A* has been generating a range of flares just about every 10 days or so. Since the passing of this past year, the activity of these flares has drastically increased, to the point of nearly every day. You may be wondering just what that means. Well, let’s look into the research from the astronomers to see just what they have been able to put together.
Utilizing the resources that the astronomers currently have at their disposal, which is 3 huge space telescopes, they have been able to piece together an extremely fascinating cosmic connection to these flares.
Gabriele Ponti, who is from the Max Planck Institute for Extraterrestrial Physics located in Germany, made this interesting comment pertaining to the flares,
“For several years, we’ve been tracking the X-ray emission from Sgr A*. This includes also the close passage of this dusty object. A year or so ago, we thought it had absolutely no effect on Sgr A*, but our new data raise the possibility that that might not be the case.”
So in short, it seems that we have been able to observe a phenomenon that has completely changed how we thought black holes functioned. An object actually exited the corona of the black hole and afterwards a flare of x-ray energy followed suit, leaving us completely baffled.
Just recently a team of researchers were able to measure the mysterious object
With the participation of the University of Granada, a team of researchers have been able to type of structure in the vastness of our solar system, despite it being more than five billion light-years away from the little blue planet we call home.
Just to put this achievement into a different perspective, our galaxy is huge and we have been able to find an object that emits an enormous amount of energy, so much so its energy can be compared to the total energy that is emitted by the entire galaxy.
The researchers were able to achieve this feat, by using the so-called gravitational microlensing effect, which is an incident that is caused by the stars that belong to our galaxy can be utilized to magnify other tiny regions in the quasar that contains this object.
Also, through this process the researchers have been able to measure the innermost edge of the disk of matter or what they call the (accretion disk) that is orbiting around this particular quasar that is called Q2237+0305, which doesn’t necessarily roll off the tongue very well, so another name it goes by is called “Einstein Cross”. Throughout the study of the changes in the type of brightness of the four images of the said quasar.
Researcher from the UGR department of Theoretical Physics and Cosmology, Jorge Jiménez Vicente, explains that,
“the breakthrough of this work has been that we’ve been able to detect a structure in the inner edge of such a small disk at such a great distance, thanks to the gravitational microlensing effect. It would be the equivalent to detecting an Euro coin at a distance of more than 100000 kilometers.”
In our galaxy, only 1 in every 500 quasars is generally affected at all by the gravitational microlensing effect. The information that astronomers have gained from this incident will be quite useful in helping us to understand the quasars, which may be essential to helping us understand just how our galaxy was born and even evolved.
“the possibility of detecting high magnification events caused by the gravitational microlensing effect could be applied to thousands of quasars.” -Vicente
When you think about how huge this object is it really makes us wonder what it could possibly be. Let us know in the comment below what theories you have about the object.

In Major First, New System Lets Paralyzed Users Control Tablet Computer Wirelessly
In what could be a major breakthrough for people suffering paralysis and other permanent disabilities, the first wireless command to a computer has been demonstrated.
According to a new study published in IEEE Transactions on Biomedical Engineering, scientists at Brown University say that the new system called BrainGate can transmit brain signals at “single-neuron resolution and in full broadband fidelity.”
BrainGate clinical trial participants with paralysis used a small transmitter connected to a person’s brain motor cortex to manipulate the interface of a tablet computer.
Participants were able to achieve the same typing speeds and point-and-click accuracy on the BrainGate system as they could with wired systems.
“We’ve demonstrated that this wireless system is functionally equivalent to the wired systems that have been the gold standard,” said John Simeral, an assistant professor of engineering at Brown University.
“The signals are recorded and transmitted with appropriately similar fidelity, which means we can use the same decoding algorithms we used with wired equipment,” Simeral said.

“The only difference is that people no longer need to be physically tethered to our equipment, which opens up new possibilities in terms of how the system can be used,” he added.
Neural interface technologies have attracted such high-profile figures as Elon Musk and social media titan Facebook in recent years.
“With this system, we’re able to look at brain activity, at home, over long periods in a way that was nearly impossible before,” said Brown University engineering professor and clinical trial leader Leigh Hochberg.
“This will help us to design decoding algorithms that provide for the seamless, intuitive, reliable restoration of communication and mobility for people with paralysis,” Hochberg added.
Scientists Discover X-Rays Coming From Uranus For Very First Time
Scientists are seeing X-rays being emitted from Uranus for the very first time, according to new research.
On Wednesday, the study was published in the Journal of Geophysical Research that lays out how a comparison of two images of the planet taken by the Chandra Observatory in 2002 and 2017 show a clear detection of X-rays in the first image, while the second shows a possible flare of X-rays on the enigmatic and icy planet.
According to NASA, the reason for these X-rays is “mainly the sun.”
However, “there are tantalizing hints that at least one other source of X-rays is present,” the space agency noted.
“One possibility is that the rings of Uranus are producing X-rays themselves, which is the case for Saturn’s rings,” NASA said. “Another possibility is that at least some of the X-rays come from auroras on Uranus, a phenomenon that has previously been observed on this planet at other wavelengths.”
X-rays can be provide a crucial window into the processes and characteristics of our universe. In the case of Uranus, these characteristics can include “atmospheric, surface and planetary ring composition.”
And while X-ray lights given off by the sun have been previously observed by astronomers on Jupiter and Saturn, this hasn’t been the case for icy giants like Uranus and Neptune.
The agency hopes that by figuring out the origin of the X-rays observed at Uranus, researchers can better grasp how mysterious objects including black holes and neutron stars emit X-rays.
Uranus is roughly four times the diameter of Earth and is the seventh planet from the sun, and is known for its distinct pair of rings around its equator and its unique side rotation.
Breathtaking New Image of Black Hole Reveals Ultrapowerful Magnetic Fields
Two years after the first-ever image of a black hole was produced, an international team of scientists have released an updated view of the magnetic fields surrounding it, saying that the groundbreaking new development allows us to understand the Messier 87 (M87) galaxy’s ability to “launch energetic jets from its core.”
In a press release, the Event Horizon Telescope (EHT) said that over 300 researchers collaborated on the project and the findings were published Wednesday in two separate papers in The Astrophysical Journal.
In April 2019, scientists from EHT captured the world’s attention by releasing an image of the supermassive black hole lying at the center of M87, which is located 55 million light-years away from Earth.
The striking image showed a dark central region outlined by a ring-like structure, which scientists described at the time as “emission from hot gas swirling around it under the influence of strong gravity near its event horizon.” In the new image captured through polarized light, brightly colored streaks of light can be seen corresponding with its magnetic field.
“We are now seeing the next crucial piece of evidence to understand how magnetic fields behave around black holes, and how activity in this very compact region of space can drive powerful jets that extend far beyond the galaxy,” said Monika Mościbrodzka, coordinator of the EHT Polarimetry Working Group and a professor at Radboud Universiteit in the Netherlands.
The new observations, which are based on data collected by EHT researchers, should provide crucial insights on how a galaxy can project streams of energy thousands of light-years outward from its core.
