New Delhi, May 24 -- Astronomers have seen something amazing in Space. Two galaxies are attacking each other like a duel.

The galaxies are moving toward each other very fast at over 1.8 million km per hour. Scientists saw this using telescopes for almost four years.

One galaxy is shooting powerful radiation at the other. It is pushing away gas clouds and stopping new stars from forming.

Researchers call this fight a "cosmic joust". These galaxies, which are 11 billion light-years away, are slowly merging into one big galaxy.

This rare event gives scientists a chance to understand how galaxies changed in the early universe when such clashes were more common.

"It's an exciting field to study. Research like this can teach us more about ...
