A very LIGO Christmas

In this exclusive comic drawn by physicist Nutsinee Kijbunchoo, the LIGO Collaboration gets a surprise visit and an unexpected gravitational-wave signal. We invite you to fill in the blank speech bubble in the last frame. Send your ideas to pwld@iop.org by 12 January and we will publish our favourites in the New Year. Merry Christmas!

Nutsinee Kijbunchoo is studying for a PhD in physics from the Australian National University and is part of the LIGO Collaboration. She draws the webcomic Antimatter (antimatterwebcomics.com)
