The brightness of the most luminous space explosion ever observed suggests that space may be more transparent than previously believed. Astronomers were surprised by the power of the light emitted during a flash of gamma rays witnessed last year. Comparing it to other gamma ray bursts, researchers estimated that such a bright event would normally occur only once in every 10,000 years.
Known as GRB221009A, this flash consisted of photons or light particles, some of which had…
