Understanding the origin of this formation may disrupt current ideas of astronomy.
- Slovak scientists are exploring different reductions in the concentrations of matter in different regions of our galaxy.
- In particular, we are talking about a phenomenon called galactic flare, while Slovaks are trying to determine as accurately as possible the characteristics of the stars that make it up.
- Thanks to this, we can find out which theory of galaxy flame formation is correct.
- In the extreme case, this may lead to a reassessment of Newton’s laws of gravity and dynamics.
Due to the low accuracy of the observations, astronomers were unable to capture some obscure structures in the Milky Way. The European Space Agency (ESA)’s Hipparchus and Gaya satellites have made significant changes in the region.
Thanks to these missions, scientists have been able to observe a phenomenon called the galaxy flame. Its mapping is handled by Slovak scientists Roman Nagy and Emil Paha of the Comenius University in Bratislava. Their results will help to better understand the structure of the Milky Way and the physiological processes that affect the structure of our galaxy.

Abnormalities in the structure of the Milky Way
It is natural to expect the density of matter to decrease as the distance from the center of the galaxy increases. Whether it is interstellar gas or stellar distribution.
Interstellar gas Atoms, molecules, and ions that freely decay in galaxies are a very rare group. It consists mainly of hydrogen and helium atoms.
However, scientists have previously observed that at a certain distance to the poles of the galaxy, i.e. up and down, the concentration decreases, getting smaller and smaller. This phenomenon is called galactic flare.
“This does not mean that there are more things in those areas. The density there is still declining, and the overall density of mass distribution is still very low,” Romanivé.sk. Roman Nagy explains.
“However, when we observe how the concentration changes with increasing distance from the equator, we see a difference compared to the center of the galaxy. The density does not decrease rapidly in each of its regions,” the Slovak astronomer added.
More accurate data reveal new phenomena
First, galaxy flames can only be observed in the distribution of galactic gas. Easier to observe than the stars.
The fact that such an anomaly applies to the distribution of stars is only revealed by data from the Hipparchus and Gia satellites. Their goal was to measure the position and speed of the stars.
Slovak scientists are using data from the Gaya satellite, which provides the most accurate data on the dynamic properties of stars in our galaxy.
“Thanks to the accuracy of these missions, we can see the best structures in the galaxy that have never been observed before,” astronomer Emil Paha told the Živé.sk editorial office.
In addition, the researchers combine this data with data from the Apogee Spectral Survey. It provides information on the chemical properties of stars.
We want to determine other parameters of these stars that are not given in the observations. For example, how the stars evolved during their age or during their lifetime. We use a variety of mathematical methods for this, “Paha added.
Based on the data obtained, Slovak created a map of the distribution of stars in the Milky Way. They are currently expecting a third hundred data from the Gaya Mission. It provides more accurate information than the second set used so far.
Thanks to the knowledge of flame-forming stars, scientists know the information that needs to be focused on in the vast information in the third dataset.
The explanation is still a mystery
The goal of Slovak scientists is to determine as accurately as possible the characteristics of the stars that form galactic flames. Then, based on that, determine which of the theories of origin of this structure is most likely.
This data will serve as a basis for other teams to create simulations of the evolution of the Milky Way to validate theories about flame formation.
An explanation of the origin of this formation may show that the current ideas of astronomy are wrong. There are several explanations for the formation of galactic flames that interfere with them.
For example, the galaxy flame could make a strong argument in favor of the existence of so-called dark matter. A theory is the product of the gravitational action of this mysterious entity.
Alternatively, information about flame-forming stars may support other theories that ultimately dark matter does not exist and that Newton’s known laws of gravitation and kinetics need to be modified.
According to another theory, the flame formed after a recent dwarf galaxy passed through the Milky Way.
