The detection was made by the High-Energy Cosmic Ray Experiment (HECR), which has provided a fresh perspective on cosmic forces. The Discovery: Antimatter from Deep Space ...

Now, an international group of physicists has proposed a connection between WIMPs and the higher-than-expected flux of antimatter cosmic rays detected by NASA’s Alpha Magnetic Spectrometer (AMS-02) on ...

Cosmic rays are high-energy particles from outer space that strike Earth's atmosphere, generating showers of secondary ...

Antimatter is important because it may help ... “Theoretical predictions suggested that, even though cosmic rays can produce antiparticles through interactions with gas in the interstellar ...

While there is antimatter in space — as we shall see, it pays us a visit in cosmic rays — on Earth, scientists have only been able to produce about 20 billionths of a gram worth of antimatter.

"[A] positron is what we call antimatter," Shao said. "It's the same as [an] electron, but it has a positive charge instead of a negative one.” The presence of positrons in cosmic ray showers ...

Cosmic rays can tell us about space and the universe. In the 20th century, cosmic rays helped scientists discover antimatter and the muon—the first evidence for subatomic particles beyond the proton, ...

"The project leaders revealed that they detected traces of antinuclei in cosmic rays, specifically antihelium, which no one expected." To understand why these antinuclei are important for WIMPs and ...
