Astronomers have found a lot of galaxies that shouldn’t exist.

Astronomers have detected something baffling at the furthest frontiers of our observable universe: massive galaxies — lots of massive galaxies — that shouldn’t even exist.
Depending on the wavelength you observe the universe in, different celestial objects and cosmic phenomena present themselves. This rule is especially true when looking deeper into the universe — the further you look, the farther back in time you can see. Because the universe is expanding, the most ancient light traveling over these vast distances becomes more difficult to observe.
This nature of space-time becomes abundantly clear when considering new discoveries in the infrared realm — light has become so red-shifted (basically stretched) that only infrared observatories can see the faint glow at the most distant corners of the cosmos.
In an effort to reveal galaxies that have remained hidden from view at these vast distances, the Visible and Infrared Survey Telescope for Astronomy (VISTA) at the ESO’s Paranal Observatory in Chile has revealed some of the youngest galaxies discovered to date, galaxies that were born a mere billion years after the Big Bang. But there’s something weird going on: There’s lots of them.And they’re monsters.
