Dr. Katie Bouman led the creation of a new algorithm to produce the first-ever image of a black hole.
Scientist Katie Bouman has said that photographing a black hole is "equivalent to taking an image of a grapefruit on the moon, but with a radio telescope." Today, the MIT postdoctoral fellow shared a photo of herself "watching in disbelief as the first image I ever made of a black hole was in the process of being reconstructed." Bouman and her team released this first-ever image of a black hole to the public, which is the first direct visual evidence that black holes exist.
More than 200 researchers have been working for more than a decade to capture this historic image as part of the Event Horizon Telescope Collaboration (EHT). The scientists combined the power of eight radio telescopes around the world to collect millions of gigabyles of data about this supermassive black hole at the center of a galaxy known as M87 using a process called inferferometry. Even with this vast amount of data, there are still gaps that needed to be filled in — which is where the work of Bouman was critical.
Starting three years ago as a graduate student in computer science and artificial intelligence at MIT, Bouman led the creation of an algorithm that took the "sparse and noisy data" collected from telescopes and turned it into an image. Over the past several years, she directed the verification of images and selection of imagining parameters. Ultimately, Bouman and her team developed multiple algorithms to piece together the picture, observing: "We didn't want to just develop one algorithm. We wanted to develop many different algorithms that all have different assumptions built into them. If all of them recover the same general structure, then that builds your confidence."
While the EHT program involved hundreds of scientists around the world, junior researchers such as graduate students and post docs led the imaging portion. Vincent Fish, a research scientist at MIT's Haystack Observatory, says that Bouman "was a major part of one of the imaging subteams," adding that "one of the insights Katie brought to our imaging group is that there are natural images. Just think about the photos you take with your camera phone -- they have certain properties... If you know what one pixel is, you have a good guess as to what the pixel is next to it." For her part, Bouman was thrilled to a leading contributor to such a historic scientific breakthrough, while also recognizing that science on this scale is always a team effort: "No one of us could've done it alone. It came together because of lots of different people from many backgrounds."
Books and Toys Celebrating Female Astronomers
When Henrietta Swan Leavitt was hired by the Harvard College Observatory, it wasn't to observe the skies herself: instead, she was hired as a human "computer," and set to studying photographic plates that male colleagues had taken at the telescope. She spent years measuring star positions and sizes and, over time, discovered that certain stars had a fixed pattern to their changes — a discovery that allowed astronomers to understand the true size of the universe and brought Leavitt recognition as a pioneer of astronomical science. Award-winning artist Raul Colon's illustrations particularly shine in this appealing picture book biography.
Caroline Herschel was the youngest child in a family where nobody expected girls to amount to much — especially once she ended up scarred by smallpox and stunted by typhus. Her family used her as a scullery maid, but her brother William saw something different in her, so when he left for England, he took her with him. Together, the astronomy-loving brother and sister built the greatest telescope of their age, which Caroline used to discover fourteen nebulae and two galaxies. She even became the first woman to discover a comet — and the first woman officially employed as a scientist. This picture book biography of the groundbreaking astronomer will inspire kids with her spirit of curiosity and resilience.
When Annie Jump Cannon first began working at the Harvard Observatory, it wasn't to look though the telescope — women weren't allowed to use it. Instead, she was hired as a "computer," analyzing and studying the data that men found when using the telescope. Cannon was assigned a challenging task: figuring out how to classify the many stars that newer telescopes and better cameras were able to spot. Cannon's classification is still use today — and she set a record for the number of stars identified and classified that stands to this day! This picture book celebrates Cannon's love of the stars and decades of hard work.

A gorgeously written novel in verse about three girls in three different time periods who grew up to become groundbreaking scientists. Maria Merian was sure that caterpillars were not wicked things born from mud, as most people of her time believed. More than a century later, Mary Anning helped her father collect stone sea creatures from the cliffs in southwest England. Intrepid and patient, she eventually discovered fossils that would change people’s vision of the past. Across the ocean, Maria Mitchell longed to discover a new comet and after years of studying the night sky, she finally did. Told in vibrant, evocative poems, this stunning novel celebrates the joy of discovery and finding wonder in the world around us.

When aspiring astronomer Henrietta Swan Leavitt took on the role of a "human computer" for the Harvard Observatory, she worked for a wage similar to what she would make working at a textile mill, despite the expertise and talent necessary. Leavitt was assigned to study variable stars, but her calculations allowed her to discover something truly remarkable: a means to measure the distance to astronomical features like galaxies and nebulae, and a new sense of how large the universe truly is. This true story of the woman who changed the way we see the night sky is an inspiring read not to be missed.
As photography began transforming astronomy, the women who worked as "human computers" would revolutionize our understanding of the universe. "The glass universe" included over half a million photographic plates, pictures of different fields of stars, and the women who studied them — including Williamina Fleming, Annie Jump Cannon, and Dr. Cecilia Helena Payne — would discover novae, design stellar classification systems, and determine what stars were made of. This fascinating story of the hidden history of astronomy celebrates the women whose contributions made our current understanding of the stars and the space they inhabit possible.
