Scientists have just discovered a massive set of previously invisible galaxies through a breakthrough new approach—by combining multiple observatories across the world and in space.

Though the Hubble Space Telescope’s foray into space gave researchers never-before-seen parts of the universe, the equipment still couldn’t see what some believed was out there—multiple galaxies waiting to be found.

Now, thanks to ALMA (Atacama Large Millimeter/Submillimeter Array), the weak light of the galaxies that was also stretched due to vast distance can actually be seen.

It’s the first time so many massive galaxies were “confirmed during the first 2 billion years of the 13.7-billion-year life of the universe,” says researcher Tao Wang at the University of Tokyo. He adds that it fills in details for “that period of cosmic evolution…details..missing until now.”

The official discovery profoundly prompts us to rethink our understanding of how the universe works and could help solve the mysteries of black matter and supermassive black holes.
