Milky Way has been ordered and aborted, new research finds | Science & Tech News



The Milky Way is not a stable disk of stars, the new research has been discovered, but virtually it has been disassembled and retired from & # 39; the center that you see.

Scientists from a Chinese Academy of Sciences & # 39; National astronomical observatories (NAOCs) have discovered the uncommon form and published findings in physics nature astronomy.

From a distance, the Milky Way sees as a dancing star of stars that each couple of hundred million years passed a mysterious center.

In the center of our galaxies is a supermassive black hole, but also hundreds of billions of stars and a great mass of darkness, all of which keep everything with the gravity.

But further away from this core core, the hydrogen atoms that make most of the gas are no longer closed to & # 39; a dark plane bound and above and below.

This S-like poisoned phenomenon is training for scientists who are trying to make the Milky Way enough.

"It is particularly difficult to determine distances from external gas parts from the Milky Way without a clear idea of ​​what the disk looks like," said Dr. Chen Xiaodian.

Dr. Chen, a researcher at NAOC and the lead writer of the study, explained that a discovery of new stars helped astronomers have a true image of & # 39; e galaxia.

"We recently publish a new catalog of well-traded dangerous stars known as classic Cepheids, of which distances can be as low as 3 to 5%," said Dr. Chen.

This new database has allowed the team to view the first exact three-dimensional image of the Milky Way & # 39; Make a way to its furthest region.

The classic Cepheids Dr. Chen described youngest stars as being up to 20 times as massive as the sun, 100,000 times as bright.

These whole stellar masses live very literally and die young, burning quickly by their nuclear fuel – sometimes in just a few million years.

One of the key signals that they release is brightness pulsations that do not last between a day and a month, and this light blood can be used to measure their distance.

"Sometimes after our surprise, we found in 3D our collection of 1,339 Cepheid stars and the gas fish of the Milky Way closely follow. This provides new insights for the formation of our home galaxy," adds Professor Richard de Grijs.

Prof de Gray, of Macquarie University in Sydney, Australia and senior co-author of the paper, added: "Somewhat more important, in & # 39; s outermost regions of & # 39; e Milky Way, we found the S-like star disk in & # 39; spiral pattern. "

"Combining our results with those other assessments, we have concluded that the Milky Way's spiral patterning pattern is most likely caused by & # 39; or # 39; or rotational supply – by the massive internal disk," Dr. Liu Chao, senior researcher and another co-author of the paper.

"This new morphology provides a critical updated map for studies of stealth motions and our origin from" Milky Way's discussion, "Dr. Deng Licai, senior researcher at NAOC and again a co-author of the paper.
