First discovered by William Herschel in 1784, NGC 6052 was originally considered a unique galaxy that simply had a strange shape.
But finally, the scientists found that the "strange-shaped galaxy" 230 million light-years away was actually two galaxies that were colliding.
NASA, previously observed with an older Hubble Telescope camera in 2015, has recently released a stunning image of the galaxies in even greater detail.

"Eventually, this new galaxy will settle in a stable form that may not resemble the two original galaxies," said the European Space Agency. A complete merger would throw the stars out of their original orbits and take new places.
According to NASA, the union of the two galaxies is both beautiful and fascinating, but also very rare, as galaxies mostly consist of empty space.
In about four billion years, the Milky Way and Andromeda collide and join together to form a single galaxy. However, scientists are still researching NGC 6052.
