The seemingly impossible, paradoxical news that astronomers had taken a picture of a supermassive black hole captured our imaginations in 2019 for good reason. What they actually showed us was a sort of shadow — a spherical blackness surrounded by a cosmic hurricane of matter and energy — but that was enough to qualify as a sign of real human progress.
And so the April announcement rose above other, less hopeful science-related news in 2019 — global warming, plastic overload, disinformation, drug overdoses and unaffordable medicine. Science, Nature and Science News all flagged the photo of the supermassive black hole — weighing an estimated 6.5 billion suns — as breakthrough of the year.
Getting that now-iconic image relied on technology that did not exist at the turn of the millennium. The leaders of the project said they counted on Moore's Law to bring the electronic advances they needed. The image was constructed from radio waves picked up at eight far-flung telescopes — from France to Hawaii to the South Pole.
