As studies on dark matter, one of space’s greatest mysteries, continue rapidly, new news has emerged from the scientific world today. Natural Astronomy Scientists have found an explanation for the mystery surrounding Sagittarius, the satellite galaxy in the Milky Way, according to research published in the journal Cell.

The new discovery confirms a theory that astronomers have long supported about dark matter. prove otherwise been quality. So what was this theory? What does this discovery tell the world of science? Let’s look at the details.

First, let’s explain what the mystery is:

The center of our galaxy reveals a pair of gamma-ray bubbles, represented by the purple segments in the image above. Although this phenomenon was discovered ten years ago, its origin remains a mystery. These radiation bubblesFermi bubbles‘ was called.

If this is one of the brightest areas in the southern part of the bubbles’Fermi cocoonwas called ‘. This structure can be seen zoomed in on the image above. The structure in question is a phenomenon that once lived in our galaxy. the result of the supernova event was believed.

That structure was actually the result of the radiation emitted by the satellite galaxy:

By examining the data from the GAIA and Fermi space telescopes, scientists were able to identify the source of the structure mentioned above. Satellite galaxy of the source of the promise Fermi cocoon comes from Sagittarius announced.

So what is the source of Sagittarius’ gamma rays?

Gamma rays from the galaxy were thought to have several possible causes, as Sagittarius contained no gas or stars. It is believed that this is one of the reasons millisecond pulsars will qualify as the biggest explanation with the new discovery. started. On the other hand, this evidence also contradicted the other theory that radiation comes from dark matter.

What is a millisecond pulsar?

Described as the core and “heart” of the celestial structures in which they reside, pulsars are neutron stars that send radio waves into space as heartbeats. Millisecond pulsars, on the other hand, are the name given to pulsars with rotational periods in the range of about 1-10 milliseconds. The generally accepted theory of the origin of these pulsars is that they were accelerated neutron stars due to the accumulation of matter from very rapidly spinning near binary stars.
