In the meantime, laboratory models are an excellent substitute and will help cosmologists know what to look for when spacecraft arrive to the actual moon.

“We call it legacy science, the things that Euclid can also do,” said Michael Seiffert, a cosmologist working on the mission from NASA’s Jet Propulsion Laboratory.

There are also similarly large structures discovered by other cosmologists - such as the Sloan Great Wall, which is around 1.5 billion light-years in length, and the South Pole Wall, which stretches 1.4 billion light-years across.

The Dark Energy Survey is an international collaboration comprising more than 400 astrophysicists, astronomers and cosmologists from over 25 institutions led by members from the U.S.

For the longest time, many astrophysicists and cosmologists have assumed that newborn galaxies would look like the orbs and spidery discs familiar in the modern universe.
