4/14/19 WILSON LUCKY SCIENCE NEWS KNOWNING MORE ABOUT BLACK HOLES Hello! What a week in science it has been! The unveiling of the first picture of a black hole was such a historic moment. Our main story of the black hole reveal is below, but there's so much more to this story we want to share. Maria Temming offered a deep dive into the technology that made this image possible. You can explore the history of our knowledge of black holes in an interactive timeline. From his Context blog, Tom Siegfried offered (what else?) context on this historic moment and thehistory of "invisible stars." Emily Conover spoke to Kazunori Akiyama, one of the first people to set eyes on the iconic image. And Emily, Lisa Grossman and Helen Thompson created a beautiful video explaining the challenges of capturing a black hole and how the Event Horizon Telescope pulled it off. There are more stories to tell about this black hole and the team that captured it, and we'll tell them in the days to come. And there was plenty of exciting science right here on Earth this week, too, so let's dive in. And thank you, as always, for reading. -Mike Denison, audience engagement editor
