Astronomers capture galactic fireworks in the nearby spiral galaxy: This impressive display of fireworks, which includes a supermassive black hole, massive shock waves and a huge gas tank, is taking place in an intermediate spiral galaxy called Messier 106.
This composite image shows the spiral galaxy Messier 106 similar to the Milky Way: 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, NASA astronomers said: Messier 106 is famous because our galaxy has two additional spiral arms, which glow with X-rays, optical and radio.
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 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.

These strange weapons do not line up with the Milky Way plane, but Let’s go with that. 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, equivalent to 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 collide with the disk of the galaxy and produce shock waves.
These shock waves, At their time, heat Gas, which is mainly composed of hydrogen molecules of up to thousands of degrees Lunar observation Messier 106 A huge bubble of hot gas under and under the plane Shows.
The scientists said: These bubbles indicate that most of the gas in the galaxy’s disks has been heated by the jet from the black hole and expelled to the outer regions. There are significant implications for the rejection of disk gas by the jet.

After a splash of media created by its own image of a supermassive black hole in the center of the Messier 87 galaxy in 2019, the Event Horizon Telescope Collaboration hopes to launch new results, this time over the black hole in the center of the Milky Way.
It can include several images and even a movie that revolves around the gas around Behmoth, called Dhanu A. Later in the year, ESA’s Gaia mission will update its 3D map of the Milky Way, which has clearly changed the way scientists understand the structure and evolution of the Galaxy.
And in 2019, gravity wave astronomers will reveal the celebrations of cosmic collisions that created space-time waves. These include several mergers of black holes, but there was already an invisible collision of a black hole and a star.
Dreams of mega colliders: CERN expects to secure funds for future mega-colliders in 2020. The European Particle Physics Laboratory, near Geneva, Switzerland, will hold a special meeting of its council in Budapest in May, where a committee will decide as part of the plan an update of the European strategy of the Laboratory for particle physics.
CERN’s proposal includes a menu of options for future colliders. The laboratory expects to build a 100-kilometer machine that can be up to six times more powerful than the Large Hadron Collider and costs up to US $ 21 billion (US $ 23.4 billion).
In the United States, the Fermi National Accelerator Laboratory, near Chicago, Illinois, must reveal the long-awaited results of the Muon G-2, a high-precision measurement of how many more siblings of electrons in a magnetic field.
Behave Physicists expect minor anomalies to reveal previously unknown elementary particles. An ambitious effort by synthetic biologists to rebuild Baker’s yeast (Saccharomyces cerevisiae) is scheduled to be completed in 2020.
Researchers, for example, have completely changed the genetic code of very simple organisms before the Mycoplasma myoids bacteria, but they do in yeast cells. Challenging due to its complexity.
The effort, called Synthetic Yeast 2.0, is a collaboration between 15 laboratories on 4 continents. The teams have replaced the DNA in the 16 S chromosomes with cerebellar variants as a cerebellar fragment. He has also experimented with the restructuring and editing of the genome.
He removal of its fragments, to understand how the organism evolved and how it handles mutations. Researchers expect modified yeast cells to achieve more efficient and inflexible methods to build a large number of products, from biofuels to medicines.
In August, the United Nations Environment Program will publish an important report on the scientific and technical aspects of geoengineering approaches that can be used to combat climate change.
These include extracting carbon dioxide from the atmosphere and blocking sunlight. Also in 2020, the International Seabed Authority will issue long-awaited regulations that will allow mining under the sea.
Scientists fear that there is not enough information on how the practice could damage marine ecosystems, with potentially devastating effects on an already stressed environment.
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 continue 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.
Which inhibit the replication of viruses transmitted by mosquitoes that cause dengue, chikungunya and zika, and allow the infection to spread to wild populations. Small essays in Indonesia, Vietnam and Brazil have shown a tempting promise.
