NASA releases stunning photos of galaxies colliding in ultra-rare cosmic event

dailystar.co.uk:

NASA and the European Space Agency have published jaw-dropping photographs of one of the universe's rarest cosmic phenomenon – and they've done it to cheer us all up after the nightmare that was 2020.

To usher in the new year with some fanfare, the two agencies – which co-run the Hubble Telescope – published a montage of six stunning galaxy mergers.The collision of two such systems is a key moment in the development of solar systems and entire galaxies, and was described by boffins at NASA and the ESA as "among the most spectacular events in the lifetime of a galaxy".Being able to study mergers is one of the best ways mankind can begin to figure out exactly how star clusters are formed, and can help us trace back the extreme physical.
