Preserved in the cave excavations of
Mogao and listing 1,339 stars the
Dunhuang Star Chart is the
oldest graphical star atlas known to exist. Dated to between 649 and 684 AD, it features two sections. The first consists of 26 diagrams of asterisms (including a recognizable Big Dipper and Orion) and the second contains 12 star maps each showing a 30 degree east-west section of sky in cylindrical projection plus an azimuthal projection circumpolar map. Star positions are accurate to within 1.5 degrees and it includes some stars in the southern sky.

"The editor's guidelines are as follows: First, remember the reader, and respect demands that we should not casually use words that are likely to offend. Second, use such words only when absolutely necessary to the facts of a piece, or to portray a character in an article; there is almost never a case in which we need to use a swearword outside direct quotes. Third, the stronger the swearword, the harder we ought to think about using it.Finally, never use asterisks, which are just a cop-out." -
