“Hello out there… we’re on the air… it’s ‘Hockey Night’ tonight.”

With the Stanley Cup playoffs in full swing, it seems appropriate to image the “Hockey Stick Galaxy” – a highly warped barred spiral galaxy in Canes Venatici. The galaxy gets its “stick” due to gravitational warping from near by galaxies like the Whale Galaxy NGC4631.
