Zuva rakaumbwa makore anenge mabhiriyoni 4.6 akapfuura kubva pakuparara kwechikamu chegore hombe remamolecular iro raive nehydrogen nehelium uye iro rinogona kunge rakabereka dzimwe nyeredzi zhinji. Zera iri rinofungidzirwa uchishandisa mamodheru emakomputa ekuvandudzika kwenyeredzi uye kuburikidza ne nucleocosmochronology. Mhedzisiro yacho inoenderana nezuva re radiometric yezvakare zveSolar System zvinhu, pa 4.567 mabhiriyoni emakore apfuura. Zvidzidzo zvemameteorite ekare zvinoratidza zvisaririra zvevana vanogadzikana vanogara kwenguva pfupi isotopes, senge simbi-60, iyo inoumbwa chete mukuputika, nyeredzi dzinorarama kwenguva pfupi. Izvi zvinoratidza kuti imwe kana kupfuura supernovae inofanirwa kunge yakaitika padyo nenzvimbo iyo Zuva rakaumbwa.
