NASA Probe Discovers 'Alien' Matter From Beyond Our Solar System
- r00fus 15y agoGlad we can prove this, but it should be obvious that our "heliosheath" is not some impervious shield that blocks out all extra-system matter. Basic cosmology/astrophysics state that heavier atoms than helium could only be created by a starving star (shed off by a nova), and the heaviest of atoms can only be byproducts of supernovae.
