... Short-lived isotopes no longer actually exist in meteorites, except for a few produced by cosmic ray interactions. They formed in other stars (and perhaps close to the Sun in our Solar System), were incorporated into solids such as meteorite parent bodies and the planetesimals that accreted to form ...

Obviously, as we orbit our central star, we are on a different side of it each season of the year. Astronomers identify constellations with the seasons in which the ...
