    Our Space Telescope looked right in the eye of this galaxy at the head of the southern constellation Hydra. The bright blue areas show recent or ongoing star formation:

    This stunning barred spiral galaxy, with a width of just over half that of the Milky Way, is brilliantly featured in this image taken by the NASA/ESA Hubble Space Telescope. Although it cannot be seen in this image, a supermassive black hole with a mass millions of times that of our Sun is known to nestle in the very center of NGC 2835.
