Astronomers have discovered a mysterious source of gamma waves in the center of a galaxy dwarf. This may indicate the presence of dark matter controversial. The discovery would be one of proportion, being the first time that dark matter could be detected without taking into account the theory of gravitational attraction.
Dark matter is an element difficult to see because neither emits nor absorbs light. Therefore, it is impossible to detect with space telescopes or other optical instruments. Theorists argue that although it is invisible dark matter exists because without it many cosmic phenomena would be impossible to explain.
Scientists say that dark matter, which would represent around 80 percent of cosmic matter is present where there is unexplained gravitational effects, but visible in contrast with observable cosmic matter.
For example, astrophysicists claim that dark matter determines the rotation of galaxies and the cosmic background radiation variations.
This finding suggests the presence of this mysterious matter in another way - through the radiation it emits.
"Something in the direction of the dwarf galaxies radiate range. There is no conventional reason for this phenomenon, therefore it could be a sign of the presence of dark matter, "says Alex Geringer-Sameth, one of the authors of the scientific paper on this topic.
The galaxy in question is called reticulum 2 and is located relatively close to our planet, ie from 98,000 light-years away.
The larger galaxies, gamma radiation generally indicates the presence of black holes, pulsars and quasars, but a dwarf galaxy is "a very clean and quiet", so the only source of this radiation could be dark matter, argue scientists.
