Detecting Giant Giant Cavity 500 Years Wide In The Milky Way

According to Space, astronomers have discovered a giant spherical cavity in the Milky Way, which is said to be formed after a star explosion, millions of years ago / 2: 02 South Study New said, spherical gaps are up to 500 light years and are in the middle of the star nursery in the constellation Perseus and the constellation of Taurus. The stars are formed from dust and gas clouds, called molecular clouds or "star nursery". Location of spherical compartments in the Milky Way (right).

. "Hundreds of stars are forming or surviving Creating on the surface of this giant cavity, "Shmuel Bialy, researcher at the Harvard-Smithsonian Harvard-Smithsonian Astronomical and Calculation Center (CFA), said." We have 2 fake Theory. First, a supernova went out of the core of the giant compartment and pushed the gas out outside, forming 'super shell perseus-taurus'
Second, a series of supernova appears in millions of years have created giant compartments over time, "said the researcher Bialy said. Using data from the Gaia spacecraft of the European Space Agency (ESA) , the researchers can first map Perseus and Taurus molecular clouds in 3D. 3D maps show that giant compartments are still difficult to grasp in previous 2D maps of this area. "We were able to see these clouds for decades, but we never know The real shape, depth or thickness of them ", co-author of the study, Catherine Zucker, researcher at CFA, said in the statement. Group of scientists have been mapping of star forming areas To better understand how the gas and dust exit in a star explosion and rearrange in molecular clouds to form new stars. Their findings show that Perseus and Taurus clouds form due to the result of the same supernova shock waves, showing the strong impact of star explosions. "This proves when one The star died, its supernova will create a series of events that can lead to the introduction of new stars, "said bialy researchers. New research is announced on September 22 Chi Astrophysical Journal Letters./.CTV Mai Trang / VOV
