NGC 3310’s spirals are readily apparent when the galaxy is viewed in H alpha light. In this false color image, bright regions are rendered in red and dim ones in blue. The image shows the location of the hottest, youngest stars as they ionize the surrounding hydrogen gas. The spiral arms are the dominant features. Extending upward on the left and downward on the right, they produce most of the galaxy’s H alpha light. The two red regions represent the galaxy’s brightest emissions. The first, on the upper left portion of the ring encircling the nucleus, is connected to one of the spiral arms. The second is on the lower right of the nucleus at the terminus of the other spiral arm.
