... We present a photometric and spectroscopic study of the unique isolated nearby galaxy KKR25. The isolated dwarf spheroidal (dSph) galaxy KKR25 was discovered by Karachentseva, Karachentsev Richter (1999, A , 135, 221) during the search of dwarf galaxies in the direction of the Local Void. In spite of its isolation KKR 25 has no gas and looks like a normal dwarf spheroidal system. ... This is the first known planetary nebula in a dwarf spheroidal galaxy outside the Local Group. ...
