The Milky Way was hiding a massive collection of new galaxies

[Mike Wehner]

• A new cosmic structure was just discovered that may hold an incredible number of galaxies, stars, and planets.
• The structure is now known as the South Pole Wall, and it resides in an area that is obscured from our view by our own Milky Way galaxy.
• The discovery was made using data showing the movement of galaxies in the area of space that is visible from Earth.

Mapping the universe is a tricky thing. Current technology allows us to observe objects that are tens of billions of light-years away, but generating maps of 3D space from our singular vantage point still poses some serious challenges. Cosmographers have developed techniques for detecting and mapping things that they can't see directly, and a new research effort has revealed the existence of a massive cosmic structure now known as the South Pole Wall.

It's a colossal collection of galaxies that measures approximately 1.4 billion light-years across. It contains countless stars and planets, and it's been hiding behind our own Milky Way. That is, until cosmographers came up with a solution.
