What Are Cosmic Rays? #SpaceSaturday « Adafruit Industries – Makers, hackers, artists, designers and engineers!


Typical knowledge tells us that cosmic rays can rework a scientist, his girl buddy, a pilot, and the girl buddy’s hot-headed brother right into a super-powered household that, when written and drawn with genre-redefining realism and eye to emotional element, can create a completely new method of telling super-hero tales. However typical knowledge additionally tells us that cosmic rays are generated by highly effective supernova blasts. A type of two statements could be unfaithful. And it isn’t the one in regards to the Unbelievable 4. Right here’s extra from Astronomy Now:

Because it seems, supernovae, which do certainly generate high-energy gamma rays, usually are not highly effective sufficient to elucidate the petaelectronvolt (PeV) energies noticed with probably the most excessive cosmic ray occasions. As an alternative of supernovae, new analysis suggests, star clusters that includes carefully packed sort O and sort B stars are accountable, performing as so-called PeVatron accelerators.

“Cosmic rays under PeV vitality are believed to return from our galaxy, however the query is what are the accelerators that may produce them?” mentioned staff chief Petra Huentemeyer, professor of physics at Michigan Technological College.
