Emerald-Cut Galaxy the rectangular-shaped galaxy (LEDA 074886)

A team of astronomers from Australia, Germany, Switzerland, and Finland, has discovered a rare, rectangular-shaped galaxy (LEDA 074886) that has a great resemblance to an emerald-cut diamond.

While using the Subaru Prime Focus Camera (Suprime-Cam) to look for globular clusters of stars swarming around NGC 1407, a bright, giant galaxy in the Constellation Eridanus and 70 million light years from Earth, the researchers discovered an unusually shaped dwarf galaxy toward the edge of their image.

Most galaxies in the universe around us exist in one of three forms: ellipsoidal, disk-like, or irregular.

Professor Alister Graham (Swinburne University of Technology, Australia), lead author of the paper describing the research, said, “It’s one of those things that just makes you smile because it shouldn’t exist, or rather, you don’t expect it to exist. Its discovery allows astronomers to obtain useful information for modeling other galaxies.”
