Let us remember (how) we were created out of ashes from nearby supernovae

"Art does not reproduce the visible; rather, it makes visible."Here is an artistic short film illustrating, in my humble opinion, the famous painter Paul Klee's quote above.




Some cosmic rays on Earth may be remnants of a "young" nearby supernova:

This illustration of the region surrounding our Solar System shows the estimated location of the two-million-year-old supernova, lying close to the galactic magnetic field, that may have been the source for some high-energy cosmic rays observed today.

More about the possible origin of the solar system formation:
About 4.6 billion years ago, a cloud of gas and dust that eventually formed our solar system was disturbed. The ensuing gravitational collapse formed the proto-Sun with a surrounding disc where the planets were born. That cloud might be similar to some region in this much larger complex of gas and dust about 4,500 light-years away in the constellation Cygnus observed by NASA’s Spitzer Telescope.
