Nerds are rejoicing over Neil deGrasse Tyson hosting the new TV show "Cosmos: A Spacetime Odyssey."
The esteemed astrophysicist is 55 and married with two teenage kids, and he's attracted a gaggle of admirers.
"It started about 14 years and 25 pounds ago," Tyson told People.
That's when Tyson was featured in the magazine's Sexiest Man Alive issue as the Sexiest Astrophysicist.
Now, with his new show on Fox and National Geographic, he's garnered a whole new group of admirers, mostly on Twitter, where he has 1.7 million followers.
"I'll Tweet something that's interesting and a little bit mind-blowing, and I'll get responses like, 'I just had a nerd-gasm,' " Tyson told People. "I say, whatever gets people interested in the universe! I'm happy to serve as a conduit to the cosmos."
Naturally, Tyson, the director of the Hayden Planetarium in New York City, has a scientific explanation for his fans' affection.
"When you tell people something that's intellectually delectable, they can feel sensually towards it," says Tyson. "But I think at the end of the day, the object of their affection is the universe."
