Discover how the James Webb Space Telescope found the oldest compact quasar pair ever seen — J1602+4228AB, nicknamed Napowawaenakaulua — just 900 million years after the Big Bang. Learn why two giant black holes, 1.5 billion and 400 million times the Sun's mass and only 18,100 light-years apart, challenge our ideas of how black holes grew so early, how the Aether survey and Gemini North confirmed the pair, and why it is only the third quasar pair found at cosmic dawn. Keywords: quasar, black hole, James Webb, JWST, cosmic dawn, Big Bang, Gemini North, Aether survey, astronomy, space, science
