A fascinating image of three galaxies colliding with each other in the farthest regions of outer space has been released by NASA.
Captured by the Hubble Space Telescope, the remarkable snapshot shows in clearer detail than ever how the galaxies, which are 684 light-years away from Earth, are in the process of merging with each other, as well as the impact this incredible collision is having on the surrounding space.
Known officially as merger event IC 2431, the collision of the three galaxies has intrigued astronomers for decades, with the event first recorded more than a century ago on February 24 1896. 126 years ago!
