In order to gain a better understanding of the center of our galaxy, which is an interstellar medium, a team of astronomers used the "Winsukinson H Alpha Maber" telescope (WHAM) to look at the heart of the Milky Way from the observation site in the state of Wisconsin. Dense gas impedes search and observation of the mysterious parts of the Milky Way.
The team of researchers focused their efforts on a Milky Way feature called "Fermi Bubbles". These bubbles are massive explosions of high-energy gas that emanate from the core of the galaxy.
While giant bubbles were observed across specific lines of vision, these observations could be made with the WHAM telescope, which is a "full horizon" telescope, and it can measure the speed, temperature and density of gas, while this was not previously possible.
It was called "Fermi Bubbles", because it was discovered by the "Fermi" telescope, which is huge bubbles, extending for a total of 50 thousand light years from the Milky Way disk, as it travels at millions of miles an hour.
Danish Krishnaro, the principal author of the study, presented his team's research to the American Astronomical Society, and before this work, some observations were made on Fermi bubbles, with ultraviolet radiation, by examining the light from faraway celestial bodies as they passed through gas. While these observations broadened scholars' understanding of bubbles, they were limited.
