[1] The movable 110 meter antenna of a radio telescope made it possible to take pictures of several neighboring regions of the sky, resulting in a folded mosaic in which an area filled with hydrogen was highlighted.
The "whiskers" have a vertical density structure suggesting that they are the walls of the bubble and were created by a lateral rather than an upward movement.
According to the Kompaneets model of an expanding bubble, the age of this system is ≈ 30 Ma, and its total energy content is ~ 10^53 erg.
This system offers an unprecedented opportunity to study several important phenomena at close range, including the evolution of superbubbles, turbulence in the HI shell, and the magnitude of the ionizing flux over the galactic disk.
Such structures are capable of influencing the distribution of chemical elements in the galaxy: heavy nuclei that are born inside stars are ejected during an explosion together with gas, which - in the form of a "superbubble" - transports them over considerable distances.
