Twisted magnetic field observed around Milky Way

Astronomers have discovered a strong and intricately organised magnetic field spiraling around the supermassive black hole at the heart of the Milky Way galaxy.

This revelation sheds light on previously unknown characteristics of this enigmatic celestial entity, which has long captivated the curiosity of scientists.

The magnetic field structure surrounding the black hole, known as Sagittarius A* (Sgr A*), bears a striking resemblance to that of the only other black hole ever imaged – the larger one residing in the galaxy Messier 87 (M87).

This discovery suggests that robust magnetic fields may be a common feature among black holes, potentially influencing their behavior and interactions with their surroundings.

Unlike the M87 black hole, which is known to launch powerful jets of material into space due to its magnetic field, similar jets have not yet been detected emanating from Sgr A*.

Dynamic nature

However, astronomers believe that such jets may exist and could be observable in the near future, hinting at the dynamic nature of these cosmic phenomena.

Utilizing the Event Horizon Telescope (EHT), astronomers have captured a new image revealing the environment around Sgr A* in polarized light for the first time.

This image unveils the intricate structure of the magnetic field, which is inferred from the polarized light emitted by subatomic particles called electrons as they interact with magnetic field lines.

Sgr A* boasts a mass equivalent to 4 million times that of our sun and is situated approximately 26,000 light-years away from Earth.

The discovery of the organized spiral magnetic field surrounding it provides valuable insights into the mechanisms governing the behavior of black holes.
