Riesiger magnetischer Halo entdeckt, der die Milchstraße umhüllt | „Diese Arbeit liefert die ersten detaillierten Messungen der Magnetfelder im Röntgenstrahlen emittierenden Halo der Milchstraße und deckt neue Zusammenhänge zwischen Sternentstehungsaktivitäten und galaktischen Ausflüssen auf.“

Summary of the article written by ScienceAlert reporter Michelle Starr:

Our little piece of the Universe is [contained within a vast](https://www.sciencealert.com/the-milky-way-is-warped-and-a-giant-blob-of-dark-matter-could-be-why) shell of [dark matter](https://sciencealert.com/dark-matter).

Though the space between the few [isolated stars](https://www.sciencealert.com/the-milky-ways-halo-of-stars-isnt-the-neat-sphere-astronomers-expected-it-to-be) scattered throughout this largely invisible sphere seems empty, there’s a lot going on out there in the wilds of the Milky Way.

By studying hot gas glowing in circumgalactic space, astrophysicists have found evidence of enormous magnetic fields that wind through and around our galaxy’s dark matter ‘halo’.

“This work provides the first detailed measurements of the magnetic fields in the Milky Way’s X-ray emitting halo and uncovers new connections between star-forming activities and galactic outflows,” [explains astrophysicist He-Shou Zhang](https://www.media.inaf.it/2024/09/23/strutture-magnetizzate-bolle-erosita/) of the National Institute for Astrophysics (INAF) in Italy.

“Our findings show that the magnetic ridges we observed are not just coincidental structures but are closely related to the star-forming regions in our galaxy.”
