Introduction
A groundbreaking revelation has emerged from the depths of the Milky Way galaxy, as astronomers have for the first time discovered a collection of extraordinary filaments hiding in its central region.
Initially observed as a singular filament near Sagittarius A*, the galaxy’s supermassive black hole, further analysis has revealed a complete population of these enigmatic structures emanating from the black hole, resembling spokes on a wheel.
This remarkable finding, detailed in a study published in The Astrophysical Journal Letters, sheds light on a distinct population of short filaments positioned near the Galactic plane.
The Astonishing Filaments
Lead by Northwestern University’s Farhad Yusef-Zadeh, the study presents compelling evidence for the existence of these intriguing filaments. The discovery came as a surprise, even to the seasoned researcher who first encountered a solitary filament in the 1980s.
The team’s extensive efforts were focused on confirming the validity of this newfound population of structures, ensuring that they were not a product of illusion or misinterpretation.

A Mystery
Previously recognized for his identification of two enormous radio-emitting bubbles adjacent to Sagittarius A*, Yusef-Zadeh employed the MeerKAT telescope from the South African Radio Astronomy Observatory (SARAO) to pinpoint and analyze the filaments.
By eliminating background interference and reducing noise in the MeerKAT images, the researcher established the existence of these filaments, altering our understanding of their orientation within the galaxy.
Vertical or Horizontal Filaments
The filaments can be categorized into two distinct orientations: vertical and horizontal. Vertical filaments align perpendicular to the Galactic plane, while horizontal filaments run parallel to it.
The vertical filaments exhibit characteristics of magnetism and relativity, involving potent magnetic forces and particles moving at near-light speeds.
Conversely, the horizontal filaments emit thermal radiation and facilitate the acceleration of material within molecular clouds. Impressively, the vertical filaments can extend up to a remarkable height of 150 light-years, significantly surpassing the length of their horizontal counterparts, which range from 5 to 10 light-years.
Origin and Connection
The team of astronomers speculates that these mysterious structures might have originated from past outflows occurring millions of years ago.
Interactions between the outflowing material and nearby objects could be responsible for the formation of these filaments.
Yusef-Zadeh emphasizes the ongoing nature of their work, highlighting the need for further observations, continuous challenges to existing theories, and meticulous analysis.
