5 Mind-Blowing New Black Hole Discoveries

Space is home to an array of bizarre and amazing objects: neutron stars, galaxy clusters, and nebulae. The most interesting of them all include black holes. From the time German astronomer Karl Blackschild first claimed their existence, as early as 1916, scientists have accumulated a wealth of knowledge about mysterious, massive objects.

As astronomy grows more sophisticated, scientists are beginning to discover more about the black hole's nature. Magnetic swirls, radio waves, wormhole theories, record-breaking explosions, In the past couple of years, scientists have witnessed it all and are now able to answer the many questions that others have asked.

Unparalleled Glimpse of Light behind a Black Hole

Black holes are cosmic giants which spit out everything and anything that comes in their path. Their gravitational pull is so massive that nothing or light will be able to resist their grip. You would therefore expect that it is impossible to see light in a black hole. Certainly, any light could have been absorbed in the first place, wouldn't you think?

Albert Einstein disagreed. In 1915, Albert Einstein, a German scientist, proposed that massive objects such as black holes would distort the structure of space and time, which would allow light to travel through them. 

This was an essential part of his general relativity theory that revolutionized the field of modern physical science. Scientists have observed this phenomenon, known as gravitational lensing, before, but no one had succeeded in detecting light coming from the black hole's interior until recently.

In July 2021, scientists from Stanford University cracked it. They were studying an extremely massive black hole located at the core of a distant galaxy called Zwicky when they saw a strange emission of X-rays that they could not identify. 

They are used to detect signals coming from the vicinity of a black hole, but the new signals are distinct. These flashes were visible later as well as the lights were much less intense, similar to echoes appearing after the main flash. 

After a lot of analysis, the scientists confirmed that the strange detections were, in reality, flashes of light that swept around the edges of Zwicky's black-hole, which once more confirmed Einstein's groundbreaking theory of relativity.

Magnetic Swirls Around the Rim of a Black Hole Captured by Astronomers

The year 2019 was the year that astronomers created history when they published the first images of the outer rim of the black hole. The black holes themselves are difficult to capture. The stunning snap of the day captured the M87* shadow, a massive black hole that is 55 million light-years away. Scientists have compiled the photo by utilizing data from a global collection of detectors dubbed the Event Horizon Telescope.

A year later, in another unimaginable feat of science, researchers revealed an unpublished image, offering additional important information about the mysterious behavior of these celestial giants. In March 2021, researchers released another picture of M87*, but this time, they showed magnetic field lines spiraling around the shadow.

Black holes, like M87*, are enclosed by a glowing band of superhot cosmic material. Scientists have studied the light coming from the region and also the direction in which the vibrations were emitted. Black holes have been famous for releasing massive streams of matter, but nobody knows what causes it. Scientists are hopeful that the magnetic swirls may be the reason for this strange phenomenon.

Objects with shape-shifting abilities lurk near the Milky Way's Black Hole.

In recent times, scientists have discovered a variety of oddly-shaped objects that are skulking within the Milky Way. Researchers from the University of California, Los Angeles found them circling the black hole in the center of our galaxies. The closest ones to the black hole appear to be the smallest. However, they start to expand when they reach the horizon of the event.

These strange gas globules have been called G objects. Scientists think they are formed by the merging of two stars with the massive gravitational pull of the sun.

Scientists have found six changing G objects within the Milky Way, although there could be other G objects throughout the Universe. Nobel Prize winner Andrea Ghez found an initial G object in 2005. However, it took seven years before scientists in Germany found the second.

When two black holes collide, they produce the light of a trillion stars.

Black holes are famous for lurking in the darkness of space, colliding into one another and merging. In the past, scientists believed that this process was not visible as it took place beneath the shadow of darkness.

Researchers think that when two black holes meet, light is released that is a trillion times more powerful than that of the sun. Ligo The gravitational waves observatory observed a stunning flare in 2019 that scientists believe was caused by two black holes merging because of the presence of an additional black hole. Dust and gas in the vicinity are like floodlights for collision, brightening the cataclysmic event.

"This supermassive black hole was burbling along for years before this more abrupt flare," says Matthew Graham, the lead writer for the research. "We conclude that the flare is likely the result of a black hole merger."

A Radio Wave Jet Photographed by Scientists

The Event Horizon Telescope (EHT) is a marvel of engineering. It is comprised of eight radio observatories scattered across the globe. Combining their data to create one huge, high-precision telescope that is the size of Earth.

In July 2021, the EHT project published a set of images showing a black hole that blasts out streams of radio waves. The black hole located at the heart of the Centaurus Galaxy is famous for releasing large amounts of energy, which is much greater than the one found in the Milky Way. 

This is the first time that scientists have observed a black hole with such clarity when it releases material out into the sky. The EHT lets scientists photograph massive jets at ten times greater accuracy and sixteen times higher resolution than before.
