Emission of muonium (μ +e-) atoms from silica aerogel into vacuum was observed. Characteristics of muonium emission were established from silica aerogel samples with densities in the range from 29 mg cm-3to 178 mg cm-3. Spectra of muonium decay times correlated with distances from the aerogel surfaces, which are sensitive to the speed distributions, and follow general features expected from a diffusion process, while small deviations from a simple roomtemperature thermal diffusion model are identified. The parameters of the diffusion process are deduced from the observed yields.
