space - When I read that a system is located x light years away, why is there no direction?

The galaxy's catalog name, SDSS J1126+2944, also gives its direction. This means the galaxy is at approximately 11h26m right ascension and 29 degrees 44 minutes north declination.

The "full name" of the galaxy, given here:

is "SDSS J112659.54+294442.8", which gives its position even more precisely. A finder chart is here:
