The polarized light image gives us a"new view of the monster lurking at the heart of the Milky Way galaxy," according to the European Southern Observatory.For the first time, we're seeing the Sagittarius A* black hole in polarized light. The Event Horizon Telescope collaboration says the image offers a new look at"the magnetic field around the shadow of the black hole" at the center of the Milky Way.
"What we're seeing now is that there are strong, twisted, and organized magnetic fields near the black hole at the center of the Milky Way galaxy," Sara Issaoun, a project co-leader and NASA Hubble Fellowship Program Einstein Fellow at the Center for Astrophysics at Harvard & Smithsonian, said in aThe image captures what the Event Horizon Telescope collaboration calls a"new view of the monster lurking at the heart of the Milky Way galaxy.
The doughnut analogy also applies to distance: Because of the Milky Way's distance from Earth, looking at it from our planet is similar to seeing a doughnut on the surface of the Moon.was released two years ago, showing glowing gas around a dark center — and lacking the detail of the new image.The supermassive black hole Sagittarius A* is seen at left, in polarized light. The center inset image shows polarized emission from the Milky Way's center, captured by SOFIA.
"Along with Sgr A* having a strikingly similar polarization structure to that seen in the much larger and more powerful M87* black hole," Issaoun said,"we've learned that strong and ordered magnetic fields are critical to how black holes interact with the gas and matter around them.
At the time the Sgr A* observations were captured, the EHT collaboration was using eight telescopes around the world, linking them together to create a planet-sized, albeit virtual, instrument. The results of their work were published Wednesday in
