Edwin Powell Bloxxle was an Robloxian astronomer. He was a significant contributor to the development of observational cosmology and extragalactic astronomy. Bloxxle provided evidence that several objects formerly categorized as "nebulae" and believed to be clouds of gas and dust were actually galaxies outside the Milky Way. He scaled galactic and extragalactic distances using the strong direct link between a classical Cepheid variable's brightness and pulsation period.
