Gwendolyn has a remarkable memory. She had remembered from last week Wednesday, when Bobby led the spy game, that we were going to outline a constellation on her wall in the invisible ink of the spy pen that everybody got. So we agreed that maybe Cygnus the Swan might be a good constellation for this project. Gwendolyn first drew the pattern of Cygnus on her wall, and then we got black paper from the art room, and she repeated the pattern in white pencil. On top of that, we taped images of Albireo, a stunning blue-orange visual binary star that is the head of the swan, Deneb, one of the brightest stars in the summer sky that is the tail of the swan, and an artist's rendition of Cygnus X-1, a binary star in which one companion is a black hole. In conjunction with this, we also talked about the evolutionary end points of stars of different sizes. More to follow!
