Date Time Share Dark Matter Particle Explorer Reports Most Precise Measurements of Cosmic Ray Proton and Helium Spectra above TeV and Reveals Chinese Academy of Sciences The Dark Matter Particle Explorer (DAMPE) collaboration reported the precise measurement of the energy spectrum of cosmic ray helium nuclei from 70 GeV to 80 TeV energies on May 18, 2021. For the first time, DAMPE reveals a softening structure at about 34 TeV energies in the helium spectrum with a high significance (~4.3σ). Together with the softening energy of the DAMPE proton spectrum, the results are consistent with a ch...

China is leading international efforts in basic research on astronomy that may help redefine our understanding of physics.

Mon, 10 May 2021 07:00 UTC Near-term models don't know whether they're coming or going. This meridional jet stream flow is throwing them for a loop. And after fooling many MSM publications into running headlines such as "Intense 10 day Heatwave set to strike Europe," the models have now flipped, and are forecasting yet more Arctic cold. "May time blizzard makes us shiver," tweeted the YorkshireSpeherdess, who runs a successful sheep farm. "You can't believe this is May," she says in the video. "It's just like the middle of winter." Paul Simons' Weather Eye article from the Saturday Tim...

On May 12, a weak Coronal Mass Ejection (CME) released from the Sun hit Earth. The event was supposed to pass by uneventfully — it would perhaps spark a few auroras, but nothing more. So how did a strong G3 geomagnetic storm ensue? Nobody was expecting a level 3 event from this CME. Nobody saw the KP Index hitting 7. © spaceweathernews.comAnd when I say nobody, I mean nobody predicted this: not NASA, NOAA, ESA or IPS in Australia. The CME's speed peaked at just 500 km/s (purple line below). This is a little stronger than your standard solar wind, but weak in terms of a Coronal Mass Ejecti...
