Summers [2] , J. DePasquale, and D. Player (STScI [3] ); Music: Into the Wormhole [4] ( Jingle Punks [5] via Youtube) Explanation: What would it look like to fly over a spiral galaxy? To help visualize this, astronomers and animators at the Space Telescope Science Institute [6] computed a virtual flyby [7] of the Whirlpool Galaxy [8] (M51) using data and images from the Hubble Space Telescope [9] . At only 25 million light years [10] distant and fully 50 thousand light years across, the Whirlpool [11] is one of the brightest and most picturesque [12] galaxies on the sky. Visible during the virtual flyby [13] are spiral arms dominated by young blue stars [14] , older lighter-colored stars, dark lanes of dust [15] , and bright red emission nebulae [16] . Many galaxies far in the distance can be seen right through M51 [17] . The visualization should be considered a time-lapse [18] , because otherwise the speed of the virtual camera would need to be very near the speed of light [19] .
