Astrophysicist Neil deGrasse Tyson has finally broken his silence after being accused by three women of sexual misconduct.

He took to his Facebook page and detailed everything in a lengthy post titled “On Being Accused.” 

“I’ve recently been publicly accused of sexual misconduct. These accusations have received a fair amount of press in the past forty-eight hours, unaccompanied by my reactions. In many cases, it’s not the media’s fault. I declined comment on the grounds that serious accusations should not be adjudicated in the press. But clearly I cannot continue to stay silent. So below I offer my account of each accusation," he wrote.

"A colleague at a well attended, after-conference, social gathering came up to me to ask for a photograph. She was wearing a sleeveless dress with a tattooed solar system extending up her arm. And while I don’t explicitly remember searching for Pluto at the top of her shoulder, it is surely something I would have done in that situation. As we all know, I have professional history with the demotion of Pluto, which had occurred officially just three years earlier. So whether people include it or not in their tattoos is of great interest to me. I was reported to have “groped” her by searching “up her dress”, when this was simply a search under the covered part of her shoulder of the sleeveless dress.

"I only just learned (nine years after) that she thought this behavior creepy. That was never my intent and I’m deeply sorry to have made her feel that way. Had I been told of her discomfort in the moment, I would have offered this same apology eagerly, and on the spot. In my mind’s eye, I’m a friendly and accessible guy, but going forward, I can surely be more sensitive to people’s personal space, even in the midst of my planetary enthusiasm," he wrote.

The allegations date back to 1984, through 2018.

Tyson is an astrophysicist, author, and science communicator and has been the Frederick P. Rose Director of the Hayden Planetarium at the Rose Center for Earth and Space in New York City since 1996.
