The other day, my colleague from Berkeley, Gibor Basri, emailed me a very interesting spectrum, asking me, "Can you have a look at this?" And I couldn't sleep, next two weeks, when I saw the huge amount of oxygen and other elements in the spectrum of the stars.
No pude dormir las dos semanas siguientes, cuando vi la inmensa cantidad de oxígeno y otros elementos en el espectro estelar.
