Astronomical observations strongly incompatible with the canonical cosmological model are reviewed. In particular too early formation of galaxies, as discovered by HST and JWST, are discussed in detail. Other data revealing highly dense population of the very young universe with plethora of other different types of objects are presented. It is demonstrated that similar or maybe even more pronounced problems can be seen also in the present day universe.

Double radio lobes are generally believed to be produced by active nuclei of elliptical galaxies. However, several double-lobed radio sources have been solidly found to be associated with spiral galaxies. By cross-matching $\sim9\times10^5$ spiral galaxies selected from the SDSS DR8 data with the full 1.4-GHz radio source catalogs of NVSS and FIRST, we identify three new spiral galaxies: J0326$-$0623, J1110+0321 and J1134+3046 that produce double radio lobes, in addition to five double-lobed spirals previously known.

The Universe expansion rate is modulated around local inhomogeneities due to their gravitational potential. Velocity waves are then observed around galaxy clusters in the Hubble diagram. This paper studies them in a ~738 Mpc wide, with 2048^3 particles, cosmological simulation of our cosmic environment (a.k.a. CLONE: Constrained LOcal & Nesting Environment Simulation). For the first time, the simulation shows that velocity waves that arise in the lines-of-sight of the most massive dark matter halos agree with those observed in local galaxy velocity catalogs in the lines-of-sight of Coma and several other local (Abell) clusters.
