Astronomers find imprint of the bubbles produced by the explosion of dying stars in our galaxy
They made this discovery by applying techniques from artificial intelligence to the HI4PI survey data,
The scientists analyzed the filamentary structure in the emission from atomic hydrogen gas
Hydrogen is the main component of stars like the sun.
Soler processed data from the most detailed whole-sky survey of the emission from atomic hydrogen in radio waves,
"These archival observations of the hydrogen emission line at 21-cm wavelength contain information on the distribution of the gas in the sky
Most of the filaments in the inner part of the Milky Way were found to be pointing away from the disk of our galaxy.
"The finding of these filamentary structures in the atomic hydrogen is an important step in understanding the process
