Astronomers discover unexplainable gas clouds

The cold gases blowing from the galaxy’s center defy our understanding of galactic winds.

The Milky Way, the center of our galaxy and home to a supermassive black hole, is a meteorologist’s dream.” It’s easy to remember that “it’s always windy. A region is a volatile place filled with gas clouds, and energetic particles rolled up by the black spot Sagittarius A* (Sgr A*) and stars near the galaxy’s center. Because of this, the winds of gas blow deep into the galaxy and eventually pass into dark space.

Astronomers have found hot, hotter, and colder gases in the wind. The temperatures range from about 1,000 degrees Fahrenheit to about 2 million degrees Fahrenheit. This research challenges some beliefs about processes at the center of the galaxy.

“The standard explanation for winds in the Milky Way is expelled by explosive events associated with black holes or from supernovae or stars.” The Milky Way’s winds are not the only explanation,” said Naomi McClure-Griffiths.

“And,” said Naomi McClure-Griffiths, an astrophysicist at the Australian National University and a co-author of the new study, “the winds are driven by supernovae or stars.

Professor McClure-Griffiths notes that galactic winds are an important process in the life cycle of a galaxy. Understanding what is happening at the galaxy’s center can help answer how galaxies evolve. To learn what is happening in the winds surrounding the galaxy’s center, the team pointed out the Atacama Pathfinder Experimental Telescope (APEX) in the Chilean desert and the Australian Telescope Compact Array at palls within a territory of the galaxy known as the Fermi bubble.
