X-rays from NASA’s Chandra X-ray Observatory are shown in blue, with much larger radio data from Carl Zanski of the NSF in purple optical data from NASA shown. The ESA Hubble Space Telescope is shown in yellow and infrared data from the NASA Spitzer Space Telescope.
Messier 106 is 20 million light years away in the small constellation of North Keynes Venetic. Also known as M106 or NGC 4258, the galaxy was discovered in 1781 by Pierre Mechin, an assistant to Charles Messier.
However, astronomers said: Messier 106 is famous because our galaxy has two additional spiral arms, which glow with X-rays, optical and radio.
These strange arms do not align with the plane of the Milky Way, but intersect with it. These additional weapons are seen in the new composite image of Messier 106. Recent observations from NASA’s Spitzer space telescope show that shock waves are heating large amounts of gas.
The equivalent of about 10 million soles.
Is it causing shock waves?
We believe that the supermassive black hole in the center of Messier 106 is producing a powerful stream of high-energy particles, the researchers said. These jets hit the disk of the galaxy and generate shock waves.
These shock waves, in turn, heat the gas. Which is mainly composed of hydrogen molecules, to thousands of degrees. The lunar observation reveals huge bubbles of hot gas on and under the Messier 106 plane.
The scientists said
These bubbles indicate that most of the gas originally present in the disk of the galaxy has been heated by jets from a black hole and expelled to the outer regions.
The rejection of disk gas by the jet has important implications for the fate of this galaxy. He estimates that all remaining gases will be pumped within the next 300 million years, until it recovers in some way. Because most of the gas in the disk has already been expelled.
There is less gas available to create new stars, he said. In fact, we use Spitzer data to estimate that stars are forming in the central regions of Messier 106, at a rate approximately 10 times lower than the Milky Way.
Using data from the ESA Herschel Space Observatory, astronomers confirmed estimates of Spitzer data from low star formation rates in the central regions of Messier 106. Herschel data was also used to make an independent estimate of how much gas resides in the center of the galaxy.
After allowing a large increase in infrared emissions due to the crash, we discovered that the mass of gas is ten times smaller than before, the researchers said. Because Messier 106 is relatively close to Earth.
We can study how this black hole is affecting its galaxy in great detail.

But the big weather event will arrive in November, when the COP26 climate conference is the moment of truth for the Paris Agreement, closed in Glasgow, United Kingdom.
Under the 2015 agreement, countries must present updated targets to reduce their greenhouse gas emissions so that global warming cannot be increased beyond 2 degrees Celsius.
But most countries have been slow to implement their promises. And the future of the treaty itself hangs in the balance: the United States is expected to formally withdraw that month. The White House and the US Congress. UU.
They must deliver graves in November, and the results can have important implications for science, especially in the weather.
A second term will to allow President Donald Trump to expose his predecessor climate policies and guarantee the formal exit of the United States from the Paris Agreement the day after the elections.
Democrats can accelerate those efforts by winning the White House or securing a majority in both houses of Congress. The 435 seats in the House of Representatives and 35 of the 100 seats in the Senate are being contested.
The dream of growing replacement organs for humans in other animals can come true as researchers progress in morally lethal techniques.
The stem cell scientist Hiromitsu Nakauchi of the University of Tokyo plans to develop tissues made of human cells in mice and rat embryos.
He would then transplant those hybrid embryos into substitute animals, a movement that was not allowed until a new law entered into force in Japan last March.
Nakauchi and his colleagues have also requested to conduct a similar experiment with pig embryos.
The ultimate goal of this research is to produce animals with organs that can eventually be transplanted into people. But some researchers think it would be safer and more effective to grow ‘organoids’ in the laboratory.

These replace the fluid that separates the electrodes inside the battery with a solid substance, increasing the amount of energy that can be stored. Solid electrolyte batteries last longer, but charge more slowly.
Astronomers reveal new details about the galaxies that make up the monster’s star ers.
An international team of astronomers from Japan, Mexico and Massachusetts Amherst, studying a “monstrous galaxy” 12.4 billion light-years away today, reported that their devices reached an angular resolution 10 times greater than before.
The structural structure of the galaxy it is completely unknown at first. They were also able to analyze dynamic properties that could not be investigated before. Details appear in nature.
So-called “monstrous galaxies” or extreme starburst galaxies are considered the ancestors of massive galaxies like the Milky Way in the current universe.
So these findings about the galaxy are known as COSMOS-AzTEC-1, which is their It gives the way to understand training and development.
The researchers say.
“A real surprise is that this galaxy is almost 13 billion years old. it is a huge ordered gas disk that is in regular rotation instead of what we expected, like a sort of disorganized train wreck that most theoretical studies predicted. “
He said he says he saw that this gas disk is now dynamically unstable, meaning that the entire gas disk that makes up this galaxy is going through a massive episode of stellar explosion.
Which explains its rate of massive star formation. Help, more than 1,000 times more Milky Way galaxy.
These more recent COSMOS-AzTEC-1 observation discoveries led to the Atacama Large Millimeter / Submillimeter Array (ALMA), a telescope and facility operated by an international association in Chile.
Ken-Ichi Tadaki is the lead author of this week’s research and a postdoctoral researcher at the Japan Society for the Promotion of Science and the National Astronomical Observatory of the Nation.
He says: “One of the best parts of ALMA observations is seeing galaxies that distant with unprecedented resolution.”
Astronomers have wondered why monstrous galaxies can make stars at such shocking speed. To begin to understand, they needed to characterize the environment around the stellar nursery. Creating detailed molecular cloud maps is an important step, he says.
- Tadaki and his team discovered that COSMOS-AzTEC-1 is rich in starlight.
- But the nature of cosmic gas in the galaxy was still difficult to detect.
- They used ALMA’s high resolution and high sensitivity to observe the galaxy.
- And detailed maps of gas and distribution movements to create the highest resolution molecular gas map of the distant monstrous galaxy ever created.
“We discovered that there are two large different clouds several thousand light-years away from the center,” explains Tadaki. “In most distant starry galaxies, stars actively form at the center. So it is surprising to find off-center clouds.”
Yun says: “How these galaxies first collected such a large amount of gas and then essentially turned the entire gas reserve into stars in the blink of an eye, which is, more commonly speaking, what we were a completely unknown question about.” You can only speculate. Now we have the first answers. “
He says: “By the time this result came from ALMA, no one knew how nature built on a grand scale, Young Bangs created just a billion years after the Big Bang. Aztec instruments 10 years ago. Finding them using was a true discovery, but it defined the explanation “.
With the new observations, team members now believe the monstrous galaxy is “powered by an extremely heavy disk that remains stable until enough gas accumulates. We still don’t know how to get so much gas so fast. It collects.
Yun says: This huge reserve of gas did not turn into fire and stars, as gas is known to do in the local universe.
Astronomers discovered that the gas clouds in COSMOS-AzTEC-1 are very unstable, which is unusual.
Once the gravitational pressure is overcome, the gas cloud collapses and forms stars at high speeds. Then, at the end of the stellar life cycle, stars and supernovae explode gases, increasing external pressure.
As a result, gravity and pressure reach a balanced state, and star formation continues at a moderate speed. In this way, the formation of stars in galaxies is self-regulating. But in COSMOS-AzTEC-1, the pressure is much weaker than gravity and is more difficult to balance.
Therefore, this galaxy shows a runaway star formation and transforms into an unstoppable monstrous galaxy. Tadaki, Yun, and their colleagues estimate that the gas in COSMOS-AzTEC-1 will be completely consumed in 100 million years, 10 times faster than other stars that make up the galaxy.
It is not yet clear why the gas is so volatile in COSMOS-AzTEC-1, but a phenomenon called “galaxy merging” is a possible cause. The galaxy’s collision efficiently transported the gas to a small area and ignited an intense star formation.
Tadaki says: “At this time, we have no evidence of a merger in this galaxy. But by looking at other similar galaxies with ALMA, we want to reveal the connection between galaxy mergers and monstrous galaxies.”
