We consider a gravitating extended object constructed from vacuum\nfluctuations of nonperturbatively quantized non-Abelian gauge fields. An\napproximate description of such an object is given by two gravitating scalar\nfields. The object has a core filled with a constant energy density of the\nvacuum fluctuations of the quantum fields. The core is located inside a\ncosmological event horizon. An exact analytical solution of the Einstein\nequations for such a core is presented. The value of the energy density of the\nvacuum fluctuations is connected with the cosmological constant.\n
