Milky Way: Scientists were surprised by a 500 light-year-wide hole found in the Milky Way

cosmos Interesting science

Astronomers studying our Milky Way Galaxy in-depth have discovered a giant cavity in space. This circular hole has been seen in the constellations Perseus and Taurus visible in the sky. This hole is 500 light-years wide. It is believed that it was formed from an ancient supernova that exploded 10 million years ago. This hole is said to be unusual because it is found in such a place where stars are being formed. Apart from this, the reason for its origin has also not been ascertained by scientists yet.

The discovery happened by chance while astronomers studied a 3D map of the surrounding region’s molecular clouds. Molecular clouds of Perseus and Tosser surround this mysterious hole. This is the area where clouds are formed. Astronomers have named this hole ‘Per Tau Shell.’ The study was published in the Astrophysical Journal Letters.

Relationship of molecular clouds of both constellations
According to this study, the Per Tau Shale observes a three-dimensional phenomenon that theoretically leads to the formation of molecular clouds and stars caused by old stars and supernova events. The team of researchers from Harvard and Smithson’s Astrophysics Center believes that the findings of this study suggest that the molecular clouds of Perseus and Taurus are not space-independent structures.

There may be two reasons
Researchers say that the molecular clouds of both constellations have been formed due to the effect of a supernova. Hundreds of stars are forming or already exist on the surface of this enormous bubble. Researchers have two explanations for this. Either a supernova exploded from the center of the bubble and pushed the gas outward into what we call the Perseus-Taurus supershell. Or this giant bubble formed from a chain of supernovae for millions of years one after the other.

Data from Giga observatory
The universe is expanding, and human’s technological reach is also extending, due to which he can get more depth information of space. The latest information results from 3D maps of the bubbles created using data from the European Space Agency’s space observatory Giga. Researchers from the Max Planck Institute for Astrology studied the bubbles using 3D maps to extract dust information.

3D maps made for the first time
For the first time, these three-dimensional maps of molecular clouds have been made. Before this, all images of clouds were two-dimensional. Researcher Katherine Zucker, who led the study, says that these clouds could be seen for decades, but their exact size could not be known. Their distance was also not known.

Without simulation
Zucker pointed out that astronomers have so far tested these things through simulations, but this is the first time they have compared theory and observations of three-dimensional scenes without simulation and tried which theory correctly fits these are working. Researchers have publicly released astronomical visualizations of this reality for the first time so that people can learn about the hole and its surrounding molecular clouds. For this, they have to scan the QR code, and all the information will be available on their smartphone.
