The baryonic dark matter dominating the structures of galaxies is widely considered as mysterious,
but hints for it have been in fact detected in several astronomical observations at optical, infrared,
and radio wavelengths. We call attention to the pattern of star formation in a galaxy merger, the
observed rapid microlensing of a quasar by a galaxy, the detection of "cometary knots" in planetary
nebulae, and the Lyman-alpha clouds as optical phenomena revealing the compact objects to be
primordial gas planets in dense clumps that merge to form stars and globular star clusters. Radio
observations of "extreme scattering events" and "parabolic arcs" are found to imply the same
population of compact planet mass objects in interstellar space, and measurement of the cometary
knots yield mass estimates of approximately earth mass as predicted. Estimates of their total number
show that they comprise enough mass to constitute the missing baryonic matter. Mysterious radio
events are explained by their pair merging in the Galaxy. Latent heat of evaporated hydrogen slowly
released at the 14 K freezing transition at their surface explains the thermostat setting of the "dust"
temperature of cold galaxy halos. The proportionality of the central black hole mass of a galaxy
and its number of globular clusters is explained.
