Scientists say they have found that “space tornadoes” turn in the middle of our Milky Way galaxy.
While the center of the Galaxy, including the supermassive black hole SGR A*, is active and filled with swirling dust and gas molecules, the process remained mysterious.
Using the Atacama-large millimeter/sub-millimeter array-a group of dozens of radio telescopes in the Chilean desert and the largest astronomical project that livelies existing concepts back the curtain and sharpen their view of the area. This is how they found the so -called “tornadoes”.
“We can envisage it as spacecraft: these are violent gas currents, they spread soon, and spread material in the environment effectively,” Xing Lu, a research professor to the Shanghai, stray, said in a statement.
Lu is a corresponding author of the study, published in the magazine Astronomy and astrophysics.
They used the functions of the telescope range to map the narrow tires within cold and dense regions in the middle of the galaxy.
‘When we watched the alma images showing the outflow, we noticed these long and narrow filaments spatially of any star-forming regions. Unlike any objects we know, these filaments really amazed us. Since then, we have been thinking about what they are, ‘explained Shanghai Jiao Tong University’s Kai Yang, which led the research.
What they found does not fit the profile of previously discovered types of dense gas philaments, and it remains unknown how it forms. But they have an idea.
This may be due to energetic shock waves, they said, referring to the presence of emissions of bright lines and other observations.
The findings provide a more detailed view of what is happening in the center of Milky Way, and suggests that there is a cyclical process of material circulating there.
Shocks would create the tornadoes and release gas. Then they would disappear to fill the material released. And the molecules that would then freeze the shock release.
The authors of the article hope that future observations using the settlement will confirm how the tornadoes are formed.
