- On 24 March 2021; first time astronomers have taken the image of magnetic field produced by the massive black hole.
- The magnetic field image of black hole has been taken by The Event Horizon Telescope (EHT) collaboration.
- It should be noted that the same team of the Event Horizon Telescope (EHT) collaboration had produced the first ever image of a black hole last year.
- EHT team has revealed on 24 March, 2021; a new view of the massive object at the centre of the M87 galaxy: how it looks in polarised light.
- This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of a black hole.
- The observations are key to explaining how the M87 galaxy, located 55 million light-years away, is able to launch energetic jets from its core.
- Astronomers explained that they are now seeing the next crucial piece of evidence to understand how magnetic fields behave around black holes.
- They said that, it can make them understand that how the activity in this very compact region of space can drive powerful jets that extend far beyond the galaxy.
- Monika Mościbrodzka, Coordinator of the EHT Polarimetry Working Group and Assistant Professor at Radboud University in the Netherlands gave the details of this observation.
- According to the astronomers the newly published polarized images are key to understanding how the magnetic field allows the black hole to ‘eat’ matter and launch powerful jets.
