An international astronomy team published a report in the latest issue of Nature, saying that they observed a huge "energy fountain" in the center of the Milky Way, and a large amount of gas emitting gamma rays erupted from supernovas there The sum of the energy produced by the explosion of 1 million supernovae.
Astronomical researchers from Australia, the United States, Italy, and the Netherlands have jointly observed this phenomenon. They said in the report that this "energy fountain" has existed for more than 100 million years, and it is mainly ejected from the supernova in the center of the Milky Way, rather than the black hole that was previously speculated.
The images obtained by the researchers through the large astronomical telescope show that this "energy fountain" is divided into two symmetrical parts, each part is up to 13,000 light-years, and the length of the two parts added up to 50,000 light-years. Erupted outward at a speed of 3.6 million kilometers per hour. The gas is full of charged particles and contains massive magnetic field energy, which is why these gases continuously emit gamma rays.
The lead author of the report, Australian astronomer Etrete Caretti, said the finding showed that from the center of the Milky Way to the marginal area, there is a large amount of flowing energy and a strong magnetic field. This may change the researchers' understanding of the halo region. The halo refers to the area of ​​the flat spherical Milky Way with relatively low density surrounding the main visible matter of the Milky Way.
Caretti said that the astronomical community had previously believed that the halo area was a "very calm place", but new discoveries overturned this view and a lot of energy would continue to flow into this area.
