Scientists hint they are close to capturing images of a black hole



Scientists have suggested that they could capture the first image of a black hole in the Milky Way.

International astronomers have observed two primary targets including Sagittarius A *, in the center of the Milky Way, and M87 in the Virgo cluster of galaxies.

The observations on these black holes were conducted by a project called Event Horizon Telescope (EHT), a series of telescopes collectively of the size of the Earth.

Astronomers now claim to have captured & # 39; spectacular data during the observations, which may include the first image of the shape of a black hole.

The image of the object would become "one of the most iconic" ever created by scientists, the researchers say.

The EHT Collaboration is analyzing the results from the first a complete set of data from the 2017, which should be unveiled this year.

A senior project scientist hinted at the Guardian that he could include the pioneering image, but was unable to comment further on talking to MailOnline.

If researchers were able to get an image it would be one of the most significant discoveries in the last 50 years of astronomy.

Sera Markoff, professor of astrophysical theoretical and astroparticle physics at the University of Amsterdam co-leads the Multiwavelength Working Group of EHT.

"If the project manages to create an image of a black hole, it would be a big problem for the fields of physics and astrophysics." Scientists have been working to achieve this for over 20 years ", he told MailOnline.

As with all scientific findings – related to Sagittarius A * data – they must first go through the peer review process before being released. [19659002] Professor Markoff said that he could not confirm whether the observations produced the first direct image of the shape of a black hole.

"Seeing these black holes in the sky is like looking at the head of a pin in New York from where I'm sitting in Amsterdam," Professor Markoff told Mail Online.

  The EHT Collaboration is analyzing the results of the first full race in 2017 and should be unveiled some time this year. If researchers were able to get an image would be a significant discovery of the last 50 years of astronomy (stock image)

"We were able to get very high quality data with the very high resolutions needed to observe the situation. shadow, if it's really there, "Professor Markoff told the Guardian.

Professor Peter Galison, who also works on the project, says that if the project is successful, the image will become the most "iconic image of science".

The picture would become one of the most significant in the last 50 years of astronomy, "said Professor Galison, who is based at Harvard University's Department of Science History.

Up So far, a black hole has never been observed.The main obstacle is that they are so compact that a telescope of the size of the Earth would be needed to capture an image of the closest to our planet.

The Event Horizon Telescope, an international collaboration, uses between 15 and 20 telescope plates worldwide to collectively observe black holes.

All telescopes must be pointed in the direction of the black hole and measure the radio waves, which are stored on hard disk banks.

Each telescope is observed individually by each area, covering the South Pole, Europe, South America, Africa, North America and Australia.

The collected radio wave data is then stored collectively on a supercomputer.

Professor Markoff said the film Interstellar includes an "idealized" grain of a black, but it is not far from what one would expect to see.

In addition to providing information on how black holes are, the data collected by the telescope could provide interesting information on how they work.

WHAT ARE THE GOOD BLACKS?

Black holes are so dense and their gravitational pull is so strong that no form of radiation can escape them – not even light.

They act as intense sources of gravity that accumulates dust and gas around them.

Their intense gravitational attraction is thought to be what stars in galaxies orbit around. [19659000] Supermassive black holes are incredibly dense areas in the center of galaxies with masses that can be billions of times that of the sun.

Astronomers believe they can form when a large cloud of gas up to 100,000 times larger of the sun, collapses into a black hole. [19659002] Many of these black hole seeds come together to form much larger supermassive black holes, which are found at the center of every known massive galaxy.

Alternatively, a supermassive seed from the black hole could come from a giant star, about 100 times the mass of the sun, which eventually turns into a black hole after the fuel finishes and collapses.

When these giant stars die, they also go to the "supernova", a huge explosion that expels matter from the outer layers of the star into deep space.

Regarding many projects that start with prototypes, the EHT team had to continuously test and update the system, starting with the combination of a few telescopes and finally with the expansion of the entire array of terrestrial dimensions. .

"The bigger the distance between the telescopes, the more details you'll see," Professor Markoff said.

From a theoretical point of view scientists already have a good idea of ​​how it should be, the first predictions on form and size have actually been made over the years & 70s.

More recently scientists both within the EHT collaboration and in the field have made complex simulations using supercomputers, in order to predict what the black hole would be.

WHAT IS THE SUPERMASSIVE BLACK HOLE SAGITTARIUS A *

The galactic center of the Milky Way is dominated by a resident, the supermassive black hole known as Sagittarius A * (Sgr A *).

Supermassive black holes are incredibly dense areas in the center of galaxies with masses that can be billions of times that of the sun.

They act as intense sources of gravity that suck up dust and gas around them.

The evidence of a black hole in the center of our galaxy was first presented by physicist Karl Jansky in 1931, when he discovered radio waves from the region.

Prominent but invisible, Sgr A * has the mass equivalent to about four million suns.

Just 26,000 light years from Earth, Sgr A * is one of the very few black holes in the universe where we can actually witness the flow of matter in the vicinity.

Less than 1% of the material initially inside the black gravitational influence of the hole reaches the event horizon, or point of no return, because much of it is ejected .

Consequently, the emission of X-ray from material near Sgr A * is noticeably weak, like that of most of the giant black holes in galaxies in the near universe.

The captured material must lose heat and angular momentum before being able to dive into the black hole. The expulsion of the matter allows this loss to occur.
