Betty White, the legendary Golden Girls actor and comedian, passed away on New Year's Eve at the age of 99. Jan. 17, would have marked her 100th birthday.

Marking the date, fans took to social media to pay tribute to White, sharing messages and images and taking part in the #BettyWhiteChallenge to raise money for animals in honour of her advocacy work. Cincinnati Zoo named a penguin in honour of her Golden Girls character, and Monterey Bay Aquarium named a giving program after her.
 

Google, meanwhile, had its own tribute — an Easter egg for anyone typing the actor's name into the search bar.
