Researchers find evidence of cataclysmic flare from the center of the Milky Way galaxy


A gigantic energy blast called Seyfert flare punched out from the center of the Milky Way around 3.5 million years ago. According to astronomers' report on October 6, 2019, more evidence has been revealed relating the Fermi bubbles – apparent remnants of a titanic explosion in our galaxy's center – in the form of two massive bursts of radiation that possibly zipped through our galaxy's poles and out into deep space. One burst must have been so extreme to spread 200 000 light-years into space, and its impact hit the Magellanic Stream – a long trail of gas from Large and Small Magellanic Clouds orbiting the Milky Way.

Astronomers said all of these events from our galaxy's center seemingly happened 3.5 million years. The blast lasted approximately 300 000 years – a very long time in human terms, but a short time on a universal scale.

According to the astronomers who discovered the flare event, "Some Stream clouds towards both galactic poles are highly ionized by a source capable of producing ionization energies up to at least 50 eV," and the ionization is associated to the blast that produced the Fermi bubbles.

10% of all galaxies are said to have Seyfert flares as well. The Milky Way is not generally considered a Seyfert galaxy, but it is known to have a 4-million solar mass black hole at its center named Sagittarius A.

Astronomers are discovering that the Milky Way can occasionally have a burst of activity even though it's not as major as those of active galaxies. The research team said the explosion about 3.5 million years ago was too massive to have been triggered by anything other than nuclear activity related to Sagittarius-A.

The lead author of the study, Joss Bland-Hawthorn from Australia's ARC Center of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) explained, "The flare must have been a bit like a lighthouse beam. Imagine darkness, and then someone switches on a lighthouse beacon for a brief period of time."

Lisa Kewley, director of ASTRO 3D, also commented, "This is a dramatic event that happened a few million years ago in the Milky Way’s history. A massive blast of energy and radiation came right out of the galactic center and into the surrounding material. This shows that the center of the Milky Way is a much more dynamic place than we had previously thought. It is lucky we’re not residing there."

The study is set to be published in The​ Astrophysical Journal.

  1. According to the basic principles of the Helical Universe, there’s nothing unusual about this finding. The highest energy blast from any galaxy can only flare up from its center. This is due to the reason that at the center of any galaxy or larger structure the intensity of the magnetic field is at maximum value. Furthermore, the highest energy particles in the Universe, both neutral and charged particles are emitted from the center of galaxies with velocities far exceeding the so-called speed of light. Read my previous article that was published in 2017. Super-intense magnetic field at the center of every galaxy


    Shrair Solar Model will reveal not only the truths about our star, and how to replicate its primary energy source, but also, the most important facts about the Universe. For instance, it will be clear that the magnetic force is the one that determines the interactions between galaxies. More importantly, it will be abundantly clear that the current view of chemical elements abundance in the Sun and the Universe, especially the percentage of hydrogen is wrong. Besides that, the model will show that black holes and neutron stars are impossible to exist. Furthermore, it will also be obvious why the concept of dark matter was introduced and what astronomical objects constitute most of the mass of the Universe
