A very early Universe is thought to be a site to create a plenty of planckeons - the particles of mass m_P~= (hbar c/G)^1/2 ~= 10-5 g and energy E_P~= m_Pc^2~= 10^28 eV. Although this very remote epoch is gone, we show that appropriate conditions to accelerate particles to Planck energies exist in the Universe even at very recent epochs in the nuclei of galaxies under certain conditions. Those conditions are met during the last stages of evolution of a supermassive rotating magnetized star - magnetoid, or spinar (L.M. Ozernoy, Sov. Astr.) 10, 241 (1966); L.M. Ozernoy & V.V. Usov, Ap. Sp. Sci. 25, 149 (1973) (P. Morrison, ApJ) 157, L 73 (1969) - before its collapse into a black hole (BH). At that stage, a potential drop near a magnetoid of a mass M approches a value of Δ V~= c^2G-1/2~= 10^27 volts independent of M - an unbeatable record ever achievable in the nature. The particles are accelerated as very narrow beams by the induced superstrong electric field up to the maximally achieved energy (N.S. Kardashev, MNRAS) 276, 515 (1995) E_max~= Z√α E_P ~ Z 10^27 eV, α being the fine structure constant. A similar process of acceleration in the vicinity of a supermassive BH^3 meets subtantial difficulties and results in much smaller energies for a BH of the same mass. We discuss the processes accompanying the particle acceleration, including interactions with ambient matter and photons and the production of hard radiation and high-energy neutrinos. A signature of the magnetoid's collapse is a specific pattern of gravitational wave radiation, which could be detected by a space detector like LISA.
