What is Xuange

Xuange shines 99 light-years away in Boötes, a white class-A star whose name comes from traditional Chinese astronomy. It means roughly «the shadowed pavilion» and belonged to the imperial constellations that organised the court's sky. The Western Boötes, the herdsman who follows the Great Bear, coexists here with the eastern cartography: two ways of reading the same strip of sky, neither more true than the other, only different in grammar.

Where it is and when to see it

Xuange lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is March, when it culminates around midnight.

  • From London it never sets and culminates about 85° up.
  • From New York it culminates about 85° above the horizon.
  • From Sydney it culminates about 10° above the horizon.

It can be seen from anywhere north of 44° S.

The light you see today left it about 99 years ago.
