ESO astronomers have released an absolutely beautiful photo taken by the FOcal Reducer and low dispersion Spectrograph 2 (FORS2) instrument on ESO’s Very Large Telescope (VLT) of an eye-catching pair of colliding unbarred spiral galaxies: NGC 4567 and NGC 4568.

NGC 4567 and NGC 4568 are a duo of unbarred spiral galaxies located about 60 million light-years away in the constellation of Virgo.

Nicknamed the Butterfly Galaxies and the Siamese Twins, these galaxies are beginning to collide and merge into each other.

Image credit: ESO.

This image shows two spiral galaxies: NGC 4567 (left) and NGC 4568 (right).

The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with the FORS2 instrument on ESO’s Very Large Telescope.

It is based on data obtained through four filters.

The color results from assigning different hues to each monochromatic image associated with an individual filter.

Two spiral galaxies undergo a protracted crash lasting two billion years, eventually merging into a single elliptical galaxy.
