Haro 11 is a messy galaxy located approximately 300 million light-years from Earth in the constellation of Sculptor. Of course, this messiness signals that the galaxy experienced turbulence in its recent past, which most likely involved another galaxy.
Besides its discombobulated shape, other evidence lingers, most prominently in the form of star formation activity. So much is presently taking place, Haro 11 is classified as a starburst galaxy.
This image, which is a composite of data gathered by the Hubble Space Telescope and the Very Large Telescope, is the brightest and most detailed yet, especially impressive given the distance involved.
