You are looking at the Alpha Magnetic Spectrometer onboard the ISS. The news is that, “after accumulating years of data, […] there are significantly more positrons than expected at the highest energies detected.” Scientists believe their origin may be the destruction of dark matter, which is amazing.
After accumulating years of data, it has now become clear that there are significantly more positrons than expected at the highest energies detected. The excess may have a very exciting and profound origin — the annihilation of distant but previously undetected dark matter particles. However, it is also possible that astronomical sources such as pulsars are creating the unexplained discrepancy. The topic remains a very active area of research.
It’s an exciting scientific discovery, but what really captures my attention is this image, of the ISS and the AMS, “with a Space Shuttle docked on the far right, a Russian Soyuz capsule docked on the far left, and the blue Earth that houses all nations visible across the background.” I still can’t believe that this thing is up there, flying at 7.71km/s. The photo is unreal.
