This view, captured by the NASA/ESA Hubble Space Telescope and released in July, shows a nearby
spiral galaxy known as NGC 1433. At about 32 million light-years from Earth, it is a type of very active galaxy known as a Seyfert galaxy--with a bright, luminous center comparable in brightness to that of our entire galaxy, the Milky Way.
