Xi
Cool red starIts story
Xi Telescopii is a red giant or bright giant about 1,080 light-years away, swollen to 56 times the Sun's radius and radiating nearly three thousand times its luminosity. An aged star whose brightness shifts slightly on a twelve-day cycle, a signature of pulsation in its atmosphere. The light arriving tonight set out when Maya civilization was raising its final temples.
