It was hiding behind the Milky Way.
Through the thick fog of our own galaxy, astronomers have spotted an ultimate prize: one of the largest-known structures in the Universe.
Called the Vela super-cluster, the newly discovered object is a massive group of several galaxy clusters, each one containing hundreds or thousands of galaxies.
“I could not believe such a major structure would pop up so prominently” after an observation of that region of space, said Renée Kraan-Korteweg, an astrophysicist at the University of Cape Town in South Africa, in a press release.
Kraan-Korteweg and her team published their discovery of the super-cluster, named after the constellation Vela where it was found, in the Monthly Notices Letters of the Royal Astronomical Society.
