Astronomers at the University of Zaragoza, King's College London and the United States Institute of Astronomy believe that the solar system is right in the middle of the so-called dark matter hurricane. This writes the science alert.
Dark matter is a hypothetical form of matter and one of the greatest mysteries of the universe. Dark matter does not emit electromagnetic radiation and does not interact directly with it – because of this, it is difficult (or even impossible) to detect it directly. Therefore, scientists rejoice with any indirect evidence of the presence of dark matter.
At this time, astronomers using the Gaia satellite were able to detect the stellar flux S1, which contains 30,000 stars. Once these stars were part of a galaxy absorbed by the Milky Way. The flow is interesting because its stars spin in the opposite direction to the direction of rotation of the solar system. Scientists suggest that this happens because dark matter moves along with the stars in this flow.
Having considered various models of density and distribution of dark matter in the S1 flux, scientists have suggested that there is a probability of detecting axons – hypothetical particles of dark matter, which are 500 million times lighter than an electron. "Ultralight particles, which we can not see, can be transformed into photons, which we can detect in the presence of a strong magnetic field," the scientists said. At the moment, this could not be done.
Recall, scientists at the University of Sapienza in Rome have reported on the invention of the device, which supposedly can prove the existence of dark photons – another hypothetical dark matter particle.
