Its story

Upsilon Serpentis accompanies the long body of the serpent-bearer, in a constellation split into two halves held up by the giant Ophiuchus across the summer sky. It is a white A-type star some 250 light-years away, hotter and more luminous than the Sun. Its light silently marks out the sinuous line of the celestial reptile, in a tracing that breaks and resumes across the firmament.
