SNOLAB is hosting its third annual Dark Matter Day poster contest. Participants are invited to create an original piece of visual artwork, in any medium, that explores the theme of dark matter. This can include the mystery of dark matter, the role that it plays in the universe, the science behind it, the people studying it, or anything they find interesting about this topic. This virtual event is open to all ages. Submissions are due on October 29th at 11:59EST.
