These two shots show two wider angles of the Ivy Mike nuclear test detonated 31 October, 1952 (1 November in some time zones) at Eniwetok Atoll in the South Pacific. We’re reposting this test not because we’re running out of nuclear images (that’s not even remotely possible), but because it’s the only test we can find that occurred on the scariest day of the year, Halloween. But if it doesn’t frighten you, consider this—an independent, non-partisan report released today reveals that the U.S., Russia, France, Israel, China, Pakistan, India and North Korea are all expanding their nuclear arsenals.
