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.
A helicopter carrying Iranian President Ebrahim Raisi and his foreign minister crashed on Sunday as it was crossing mountain terrain in heavy fog.
The official said the lives of Raisi and Foreign Minister Hossein Amirabdollahian were “at risk following the helicopter crash”, which happened on the way back from a visit to the border with Azerbaijan in Iran’s northwest.
“We are still hopeful but information coming from the crash site is very concerning,” the official told Reuters, speaking on condition of anonymity.
State TV quoted an official as saying at least one passenger and one crew member had been in contact with rescuers. It also said the helicopter had been found, though Iran’s Red Crescent denied this report.
Iranian Supreme Leader Ayatollah Ali Khamenei, who holds ultimate power with a final say on foreign policy and Iran’s nuclear programme, sought to reassure Iranians, saying there would be no disruption to state affairs. #iran #trending
Australia’s multimillion-dollar campaign to attract Hollywood productions to its shores appears to be paying off.
The allure of Australia lies not only in its picturesque locations but also in its competitive financial incentives.
The government offers generous rebates and tax breaks to international productions, making it an attractive proposition for filmmakers looking to maximise their budgets.
Despite the recent intake of Hollywood productions down under such as ‘The Fall Guy’ and ‘Furiosa: A Mad Max Saga’, Aussie independents are still finding the space to carve their own creative path.
Rob Fantozzi joined the program to discuss the latest in Hollywood, and showcased his own upcoming project – ‘Omerta‘. #featured
