In space, traces of dark matter

Researchers from NASA and the U.S. Department of Energy announced an interesting finding, which could be key to unlocking the universe. Alpha Magnetic Spectrometer (AMS), installed on the International Space Station, has found particles that may be part of the dark matter . Unexplored substance forms a significant part of the mass of the universe. Until now, scientists have not been able to detect dark matter.

“These findings point to the dark matter. We need to study the time ”

– Said principal investigator Samuel Ting, AMS during the press conference.

Hypothesis of the existence of dark matter are built in 1930, when astronomers noticed that some stars and clusters of galaxies are not moving at the speed calculated based on the number of visible matter. The theory assumes that there is dark matter, to influence the cosmic body. The problem is that it could not manage to find. Recent studies have reinforced this theory: scientists today suggest that more than 80 percent of the matter in the universe is formed by a “black” matter.

Alpha magnetic spectrometer, a $ 2 billion is designed to search for dark matter by collecting high-energy radiation, or so-called cosmic rays, followed by sorting them to a class of particles, which, presumably, formed after the collision and the destruction of two dark matter particles.

In the first 18 months after the launch of AMS analyzed 25 billion cosmic rays and discovered a 400,000 positrons, which are the traces of black energy. Scientists find happy, but definitive evidence for the existence of dark matter in them yet.

“In the coming months, AMS will give us a definite answer to the question of whether these positrons signal of dark matter, or they have a different origin,”

– Says Ting.

Trapped positrons could also be formed inside stars, called pulsars, although all traces indicate dark matter.

AMS – a joint initiative of 56 scientific institutions from 16 countries. Project management team carries the Johnson Space Center in Houston (Texas, USA) under the leadership of Samuel Ting, a Nobel Prize-winning physicist, scientist at the Massachusetts Institute of Technology and the European Organization for Nuclear Research (CERN). It is expected that AMS will last 10-18 years, collecting about 16 billion cosmic ray annually.

Dark matter is one of the most mysterious phenomena in the universe .
