Astronomy Science ~ This galaxy is called by the nickname "emerald pieces". Unique rectangular galaxy was discovered by a team of international astronomers and Swinburne University of Technology in Australia. Astronomers gave the name of the galaxy as LEDA 074 886 which is a dwarf galaxy located 70 million light years from Earth and 250 galaxies belonging to the other group.

"It is exciting to be discovered" stated Dr Alister Graham at the Center for Astrophysics and a super computer at Swinburne University. "I has seen thousands of galaxies, and they do not look like this," he added.

Quoted from universetoday.com, LEDA 074 886 galaxies found by using the Japanese Subaru telescope by astrophysicist Dr Lee Spitler. It is estimated that the odd shape of the galaxy is caused by a collision between two galaxies may be larger than the galaxy NGC 1407.

Initially we thought that there might be some gravitational tidal interactions that have caused 074 886 LEDA galaxy has an unusual shape, but we are not so sure. We are more confident that the unusual shape of this resulted from the collision of two disk galaxies, "said Dr. Graham.

In addition to its odd shape, LEDA 074886 also has a disk (disc) star in it parallel to the long line of galaxies. The star disc rotates at a speed of 33 km per second.

Although the rectangular shape of the galaxy is rare, but it is becoming part of some form galaxies. Dr Graham said, "if the orientation was just right, when our galaxy collide with the Andromeda galaxy three billion years from now, we might see a rectangular-shaped galaxy."
