No one has ever seen a black hole, as their powerful gravitational force prevents us from seeing anything that enters it. Scientists believe that when a star dies, it collapses in on itself, creating a black hole.
These “invisible” objects can have up to several times the mass of our sun, and they appear as dark areas in space when viewed through telescopes. However, since they do not emit any kind of light or radiation, we cannot observe them directly.
instead, scientists observe the effect of black holes on nearby objects and infer their presence through indirect means. For example, if a black hole is located near a star, its gravitation pull can cause the star to move in an irregular pattern, giving us clues as to their existence.
What did NASA see come out of a black hole?
NASA has not yet had the opportunity to directly observe any material being ejected from a black hole. However, indirect evidence of outflows from black holes has been observed. This evidence generally takes the form of jets of particles and radiation being emitted from the vicinity of the black hole.
It is believed that these jets are the result of material being released from the disk of material that can collect around the black hole. This is known as an accretion disk. As the material in the disk falls towards the black hole, its violent motion can create a vacuum, or “wind”, of high-energy particles and radiation, or what we would call a jet.
This material is then pushed outwards from the black hole’s powerful gravity, forming jets of radiation and particles. Furthermore, computer models of these jets suggest that some of the material may escape the black hole, allowing it to escape into its environment.
Is there a real photo of a black hole?
Yes, there is a real photo of a black hole. The photo was taken by the Event Horizon Telescope, which is a global, Earth-sized array of eight ground-based radio telescopes. The telescope took the image of a supermassive black hole, located in the center of Messier 87, a massive galaxy in the nearby Virgo galaxy cluster, on April 10th, 2019.
The particular black hole is several billion times more massive than the Sun and lies about 55 million light-years away from Earth. The resulting photo shows a bright orange and yellow ring encircling a dark circle in the center.
The dark circle in the center is the edge of the black hole’s event horizon, beyond which not even light can escape. The photo is the first direct visual evidence of a supermassive black hole and its shadow.
It has been described as a “groundbreaking discovery” that could open up a new era in physics and astronomy.
Did a black hole swallow a planet?
No, a black hole cannot “swallow” a planet. A black hole is an object so dense and its gravitational pull is so strong that not even light can escape its grasp. Because of its powerful gravity, a black hole can pull objects around it, such as gas, dust and even stars.
When a black hole is close enough to a star, it can suck material into it, creating a violent reaction known as an accretion disk. If a planet were to get too close to a black hole, the intense gravity would cause the planet to be stretched and torn apart in a process called spaghettification.
This would occur before the planet ever gets close enough to the black hole to be swallowed.
What happens when a black hole dies?
When a black hole dies, it means the black hole has completely evaporated away. This is known as Hawking Radiation and it happens when the black hole has lost all its mass, typically through the radiating away of small amounts of energy via a process of quantum-mechanical tunneling.
As the mass of the black hole decreases, Hawking radiation increases until the black hole has completely evaporated. This process is incredibly slow as the process of radiation is so small that it takes an infinite amount of time for the black hole to completely evaporate away.
It is thought that nothing remains of a black hole once it has died and that the matter that initially formed the black hole is returned to its constituent particles which then become part of the universe again.
What came out of black hole recently?
In April 2019, scientists detected a mysterious signal coming from a supermassive black hole in a galaxy about 750 million light years away. This strange signal was picked up by the Very Large Telescope Interferometer, which consists of four 8-meter-aperture dishes, located in the Atacama Desert in northern Chile.
The signal was incredibly low-frequency and is believed to be the emission caused by interactions between two supermassive black holes, spiraling around and eventually merging together. This would be the final stage of galactic evolution, known as the “last parsec problem,” where any two black holes orbiting each other should eventually coalesce into one.
This is also the same process believed responsible for gravitational waves, which were discovered in 2015.
This detection of the mysterious signal is the first observational evidence of two supermassive black holes in the process of merging. It also provides further support in the theory that supermassive black holes are the most effective sources of gravitational waves.
This discovery is an exciting step forward for astronomers and may hold the key to understanding many of the unsolved mysteries about the universe and the phenomena it contains. It also advances further our understanding of the formation of galaxies and the processes that power them.
Did NASA find out what a black hole sounds like?
No, NASA has not found out what a black hole sounds like because sound is a vibration of air molecules, and there is no air in space. However, NASA was able to create an audio representation of what a black hole might sound like by using data from the Laser Interferometer Gravitational-Wave Observatory (LIGO).
The LIGO project has been able to record gravitational waves that are created when two black holes collide. By analyzing this data, scientists were able to create a sound wave representation of a black hole.
It can be heard as a low-pitched rumbling sound that races across the cosmos.
When was the last black hole seen?
The most recent black hole to be discovered was seen in late January of 2019. The black hole, named M87*, was first detected by the Event Horizon Telescope, a worldwide collaboration of eight radio telescopes.
The discovery of this supermassive black hole located in galaxy Messier 87, some 55 million light years away from Earth, was reported by the New York Times on April 10, 2019. The black hole is 6.5 billion times the mass of the Sun, making it the largest black hole to be seen to date.
It is noteworthy for the first-ever image of a black hole, which was captured using the Event Horizon Telescope. The discovery of this extremely distant black hole not only sheds light on the nature of black holes, but also the structure of our universe.
How close have we gotten to a black hole?
We have not been able to get particularly close to a black hole in terms of physical distance. Black holes can have incredibly powerful gravitational forces which makes it difficult for us to get close.
On the other hand, we do have a reasonably good understanding of the physics of black holes. We are able to make observations of them from our telescopes and study the environment around them. We have developed mathematical models that accurately describe the behaviour of these objects and are able to track their movement.
We have even been able to ‘hear’ black holes in the form of gravitational waves, allowing us to have an unprecedented insight into their properties. Therefore, although we are still quite far away from a black hole in terms of physical distance, we are getting much closer in terms of our understanding of them.
Is there a black hole near Earth?
No, there is not a black hole near Earth. Black holes are incredibly dense, massive objects that are created when a massive star collapses in on itself. They are incredibly difficult to detect, given their large mass and very small size.
The closest black hole to Earth is V616 Monocerotis, also known as V406 Mon, which is located about 3,000 light-years away from us. Therefore, it is not possible for a black hole to be near Earth, since it would be far too distant for us to detect it.
Do we have any real pictures of black holes?
Yes, we do have real pictures of black holes. On April 10th, 2019, the Event Horizon Telescope (EHT) Collaboration released the first-ever image of a black hole, located in galaxy M87, located 55 million light-years away from Earth.
The image captures the black hole’s shadow, which is created by the bending of light around the black hole due to its immense gravity. Images of the accretion disc of the black hole were also released by the ETOH, although the black hole itself is not visible (black holes emit no light).
Interestingly enough, the black hole has a mass 6.5 billion times that of the sun and is larger than our solar system. The EHT collaboration also released an image of another black hole, located in galaxy Messier 87, located 557 million light-years from Earth.
This black hole appears to be smaller in size than the one previously discussed, though it’s still larger than our solar system.
In addition to the two images released by the EHT, other organizations are also working on capturing more images of black holes. The Juno spacecraft launched by NASA in 2011 has been capturing the space surrounding the black hole GRS 1915+105, located 33,000 light-years from Earth.
Data from Juno’s observations is expected to be analyzed in 2022, with the intention of creating a high-resolution image of the black hole.
So in conclusion, while we don’t have any actual pictures of the interior of black holes yet, we do have real images of the shadows of them, as well as hopes of future images.
Did NASA take the picture of the black hole?
No, NASA did not take the picture of the black hole. The picture was produced by the Event Horizon Telescope (EHT), an international project involving scientists from around the world, including NASA.
The EHT was used to take an image of the supermassive black hole located at the center of the Messier 87 galaxy by combining astronomical data collected by eight radio telescope observatories on four different continents.
It took two years of data collection and a two-year-long process to assemble the data and make the first-ever image of the black hole, which was released in April 2019. The data was used to create a portrait of the black hole’s shadow, which is the only way to view it since it does not emit light of its own.
NASA worked closely with the EHT project, providing technical and administrative support, as well as resources for the data analysis.
Who proved black holes are real?
The first person to theoretically propose that black holes exist was the German astronomer Karl Schwarzschild, in 1916. His paper, “On the Gravitational Field of a Mass Point According to Einstein’s Theory,” laid the framework for the concept of a black hole as we know it today.
However, it wasn’t until the 1930s that astronomers began to take the idea seriously. It wasn’t until the late 1960s and early 1970s that black holes were proved to be real.
In 1971, a team of astronomers led by Bruce Balick and Robert Brown at the University of Washington used a combination of radio and X-ray observations of a bright source in the constellation Cygnus to discover the first conclusive evidence of a black hole.
This black hole – Cygnus X-1 – has since been studied in more detail than any other black hole.
In 1974, astronomers Thomas Bolton and Douglas Minkowski from the California Institute of Technology observed the binary star system in the constellation Ophiuchus, known as Cygnus X-3, and realized it was a black hole.
Following this, two X-ray sources, known as OJ287 and MCG-6-30-15, were suspected of being black holes. Subsequent observations confirmed their suspicions, confirming that black holes do indeed exist in the Universe.
What would a black hole actually look like?
A black hole is an incredibly dense and powerful object that has such a strong gravitational pull that even light cannot escape its grasp. Because of this, black holes are actually invisible to the eye, as light cannot escape from within the event horizon.
However, astronomers have been able to peer into these dark regions of space to detect the effects of a black hole, such as the intense gravitational pull on surrounding objects and the bending of light by its immense gravity.
Many black holes are seen as accretion disks, which is the matter, such as gas, dust, and stars, that’s been pulled into the hole and is now orbiting around it. This matter, when viewed with powerful telescopes, forms a disk-shape, as it is moving so quickly around the hole that it emits a bright light.
This can also cause jets of material to be launched in opposite directions, forming a ring-like structure around the center, which can be seen from a great distance across the universe. So while we cannot actually see a black hole, the effects it has on its surroundings can provide us with a better understanding of just how powerful, and potentially dangerous, these objects can be.
How many black holes have been observed?
Black holes are some of the most mysterious and powerful objects in the universe, and to date, scientists have observed and identified around 30 of them. The census is thought to be much higher, however, as some estimates suggest that there could be more than 100 million black holes sitting in the center of our own Milky Way alone!
As of May 2020, the most accepted catalog of black holes was compiled by the Chandra X-ray Observatory, which identified around 26 confirmed black holes throughout the Milky Way Galaxy, as well as 33 stellar-mass black holes, or black holes formed by the death of a single star.
Additionally, scientists have also identified and confirmed around 34 intermediate-mass black holes.
Thanks to X-ray telescopes and other observatories in space, scientists are now able to observe the effects of a black hole and even detect its presence before it can be seen visually. For example, the nearby Sagittarius A* black hole, located at the center of the Milky Way galaxy, was first detected via radio wave emissions in 1974 before being noticed by an X-ray telescope in 2019.
