If something sounded a little familiar during Sunday’s (April 27) episode of “Cosmos: A Spacetime Odyssey” on FOX, that might be because two noted actresses lent their voices to the program.
Kirsten Dunst voiced Cecilia Payne, a British astronomer responsible for discovering the chemical composition of stars. Marlee Matlin also appeared as the voice of American astronomer Annie Jump Cannon, who first catalogued the spectral characters of stars.
“Yes, that’s me as the voice of Annie Jump Cannon on #Cosmos,” Matlin tweets. “Thanks to my friend @SethMacFarlane.” You can watch their episode of “Cosmos,” “Sisters of the Sun,” above.

Chris E. Hayner is equal parts nerd, crazy person and coffee. He watches too much TV, knows more about pro wrestling than you do and remembers every single show from the TGIF lineup. You may have seen him as a pro-shark protester in "Sharknado 3." His eventual memoir will be called "You're Wrong, Here's Why..." TV words to live by: "I'm a firm believer that sometimes it's right to do the wrong thing."
