How the universe got its large magnetic fields has remained one of the stickiest outstanding problems in astrophysics. Now, ...

Astronomers have developed an ingenious way to measure the magnetic field of the Milky Way using polarized light from interstellar dust grains that align themselves to the magnetic field lines.

Seen in polarised light for the first time, the image above is of Sagittarius A*, the supermassive black hole at the center of the Milky Way—or, rather, the magnetic field around its shadow.

"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," ...

Dubbed Sagittarius A* (Sgr A*), this colossal black hole resides at the heart of the Milky Way ... twisted and systematically organised magnetic field enveloping the black hole.

which in turn lies within other magnetic fields stretching across the Milky Way—and perhaps even beyond. This scalar trail is long and tenuous, but it may trace all the way back through time and space ...

First-Ever Magnetic Map of Milky Way’s Black Hole Reveals a Mystery Polarized light from Sagittarius A*, our galaxy’s supermassive black hole, shows swirling magnetic fields that may hint at ...

Our little piece of the Universe is contained within a vast shell of dark matter. Though the space between the few isolated stars scattered throughout this largely invisible sphere seems empty ...
