One of the greatest mysteries the James Webb Space Telescope (JWST) was developed to investigate was the birth of supermassive black holes (SMBHs). For more than twenty years, astronomers have puzzled over how these gravitational behemoths - weighing millions to billions of solar masses - could exist less than a billion years after the Big Bang. According to the most widely accepted cosmological models, massive black holes did not have enough time to form through the usual processes of black hole formation and mergers.

Launch is probably the one most commonly thought of, another is “first light” of all of the instruments on the telescope. Ultimately, they’re responsible for the data the telescope is intended to collect - if they don’t work properly then the mission itself it a failure. Luckily, the Interstellar Mapping and Acceleration Probe (IMAP) recently collected first light on its 10 primary instruments, and everything seems to be in working order, according to a press release from the Southwest Research Institute who was responsible for ensuring the delivery of all 10 instruments went off without a hitch.
