#cosmicrays — Public Fediverse posts

#Radiation measurements on a recent #flight I was on, it is interesting to see that immediately after takeoff, the rate drops significantly and only goes up higher again once you gain altitude. I guess it's due to the proximity to the ground and all that concrete and #rock #geology near the surface and then the #CosmicRays in the upper #atmosphere.

There was one #HighEnergy event on the next flight. Probably due to a cosmic ray.

A fly through of the Auger Observatory

Located on the vast plain known as the Pampa Amarilla (yellow prairie) in western Argentina, this hybrid detector employs independent methods to detect and study the highest-energy cosmic rays.

Its 1,660 water surface detector tanks, separated from each of its neighbors by 1.5 kilometers, cover about 3,000 km2 of the Pampa.

New study by Teresa Bister and Glennys Farrar on the anisotropies in the ultra high energy cosmic rays arrival directions, using the 3D source density calculated from galaxies' peculiar velocities.

#Voyager found that 75% of the #CosmicRays heading our way from #InterstellarSpace 🌌 get filtered out in the #heliosphere’s outer reaches. If the encounter with the next cloud squeezes the heliosphere all the way down to #Earth’s #orbit, life forms would be exposed to an intense #radiation environment that would riddle #DNA 🧬 with mutations. There’s evidence of such an event around the time early #hominids were just beginning to pick up stone tools https://www.science.org/content/article/voyager-steroids-mission-probe-mysterious-region-beyond-solar-system

Another feature that you can see in #ESAEuclid's first images: What are these? Satellite streaks 🛰️? Asteroids ☄️? Superwoman (or Superman) 🦸🏽 ?

No, much smaller: these are traces by #CosmicRays ⚡, hitting #Euclid's #VIS and #NISP detectors directly, depositing energy and electric charges in their pixels.

`For the team of researchers, these results are pretty clear. “Hence, we suggest that GCRs (Galactic Cosmic Rays) and SEP (Solar Energetic Particle) events from the young Sun represent the most effective energy sources for the prebiotic formation of biologically important organic compounds from weakly reducing atmospheres.”`
