A galaxy unlike anything seen before, just 800 million years after the Big Bang, is producing stars 180 times faster than the Milky Way, astronomers have said.

The findings about Y1, published in Monthly Notices of the Royal Astronomical Society, reveal how quickly galaxies could form in the early universe. This cosmic ‘star factory’ glows with superheated cosmic dust, and by measuring its temperature, scientists studied how it formed stars.

The discovery is particularly fascinating because the first generations of stars, known as "Population III (POP III)," formed under conditions very different from those in nearby galaxies today.

How did scientists discover the Y1 galaxy?

Scientists used the Atacama Large Millimetre/submillimeter Array (ALMA), a powerful telescope in Chile made up o
