    Unibertsoko objektu dentsenen sekretuak aztertzen ditugu: zulo beltzak, non argia ere harrapatuta geratzen den, neutroi izarrak beren sinesgaitzeko dentsitateekin, eta pulsarren erritmo kosmikoak.

    Izarren Heriotzatik Jaiotako Misterioak

    Best quote from Izarren Heriotzatik Jaiotako Misterioak

    “

    Supernoben eztanda hauek ez dira soilik heriotza-momentuak; sorrera-momentuak ere badira. Gure gorputzeko karbono-atomoak eta odoleko burdina izarren barruetan sortu ziren duela milioika urte; Carl Sagan-ek esan zuen bezala, 'izar-hautsa gara.'
