She brought the outer planets into sharp focus, leading the charge to watch a comet slam into Jupiter and shaping the next generation of space exploration.
Heidi Hammel didn't just look at the stars; she made the solar system's most distant, enigmatic worlds her personal laboratory. A planetary astronomer with a gift for leadership, she cut her teeth on the Voyager 2 team, helping to decode Neptune's blue mysteries. Her defining moment came in 1994 when she spearheaded the Hubble Space Telescope campaign to witness the fragments of comet Shoemaker-Levy 9 pound Jupiter—the first direct observation of a cosmic collision. That work cemented her reputation for orchestrating complex, urgent science. Hammel's relentless scrutiny of Uranus and Neptune, using Hubble and the Keck Observatory, peeled back layers of their dynamic atmospheres, tracking storms and deciphering ring systems. Her deep expertise earned her a pivotal role as an interdisciplinary scientist for the James Webb Space Telescope, ensuring its instruments would continue to probe the questions she helped define. Beyond her research, she became a powerful voice for public science communication, translating celestial wonders into compelling stories.
1946–1964
The largest generation in history at the time. Shaped by postwar prosperity, the Vietnam War, the sexual revolution, and Watergate. They questioned every institution their parents built — then ran them.
Heidi was born in 1960, placing them squarely in the Baby Boomers. The events that shaped this generation — postwar prosperity, civil rights, Vietnam, and the counterculture — shaped the world they entered and the choices available to them.

She is a trained classical flutist and once considered a career in music before turning to astronomy.
An asteroid, 3530 Hammel, is named in her honor.
She served as Vice President of the American Astronomical Society's Division for Planetary Sciences.
Hammel is a strong advocate for women in science and has spoken widely about balancing a research career with family life.
