The sky turned into a massive blaze of bubbling gas shining out of our galaxy’s center around 3.5 million years from now. It was a real sight for the early ancestors of today modern humans. And there might be a chance that we can catch a similar event with our own eyes. The explosion mentioned before stated as Fermi Bubble. It was our galaxy discharging a considerable amount of nuclear energy. This explosion includes deadly ionizing radiations originating from the supermassive black hole present at the center of the Milky Way. According to the new study published in arXiv, the preprint site, this epic spectacle took place approximately 3.5 million years ago.
This discovery is reshaping views about our galaxy, which is far more active than we supposed. For the decades, though astronomers have seen smaller burps at the center of our universe, they never observed something quite this intense. Bland-Hawthorn was the lead author, and he is the director of the Sydney Institute for Astronomy. He said in the interview, it is a fantastic thought, that if cave people had looked in the direction of our galaxy’s center, they would have seen some giant ball of heated gas. He further said that it must have been an extraordinary spectacle.
In the interview with Astro 3D, he further stated that, consider that flare as a bit like a lighthouse beam. Consider immense darkness, and then suddenly someone switches on the lighthouse beam for a very brief moment, and the condition is you didn’t have to blink. The scientists further estimated that the event must have lasted for around 30,000 years that is an eternity to humans, but in galactic terms, it would be a short blip. For in-depth studies regarding the explosion the researchers studied the data that was collected by the Hubble telescope. The findings are significantly significant as it could provide insights about the celestial body formation. Further Bland-Hawthorn added that the event might happen again.
