New Google Doodle partway through today honors picture of black hole

This is the first time I’ve seen the Google Doodle change partway through the day. It’s so new, in fact, that I can’t link to it except through the Google website itself. It honors the picture of the Black Hole just published today

China’s version of Google also commemorates the black hole, but their doodle is different – Baidu Celebrates Black Hole Image With Cheery Doodle

Has anyone noticed the black hole is SMILING?
