Scientists have spotted one of the most distant (and therefore the youngest) example of merging galaxies yet observed, according to new results.

The team of researchers in Japan observed a distant source of light called B14-65666 using the Atacama Large Millimeter/submillimeter Array of telescopes in Chile. Higher-resolution data from light emitted by oxygen and carbon ions suggested to the researchers that the object might be a single galaxy quickly forming new stars as the result of a collision.

Thanks to the fact that light has a top speed, looking farther into the distance reveals information about increasingly earlier times. Scientists therefore hope to retell the history of the universe, how it evolved and ended up looking the way it does today, by observing the most distant objects.
