BOSS stand for the Baryon Oscillation Spectroscopic Survey.

BOSS is a superstructure collected of superclusters which are unified by gasses, located billions of light years gone from our plant, and its mass is ten thousand times bigger than that of our galaxy, the Milky Way. Thanks to Gravity, these superclusters are able to stay interlock while they journey crossways space.

According to Joshua Sokol at latest Scientist, the megastructure exposed by a team from the Canary Islands organization of Astrophysics is composed of 830 separate galaxies and has a mass 10,000 times greater than the Milky Way. To put the scale of this arrangement into perspective, we orbit one single star, the Sun. Our galaxy, the Milky Way, has over 200 billion stars, presently like our Sun, in it alone with an unknown total of planets orbiting them.

However, even though BOSS is the biggest ‘thing’ ever discovered in the known universe, not all researchers agree it should be categorized as a ‘structure.’ The arguments next to BOSS being called a structure or superstructure are that these superclusters aren’t connected like a partition would be. Instead, they have ‘dips’ and empty spaces among them and are linked by clouds of dust and gas.
While the debate whether or not BOSS is a superstructure or not will carry on, it still is the biggest object still spotted by scientists. In fact, there are numerous other ‘great wall’s or superstructures establish floating in the emptiness of space, situated thousands and even millions of light years away from our planet.

Other Structures alike to BOSS are the Sloan huge Wall, which was exposed by researchers in 2003, and Lanikea, the superclusters of galaxies where our galaxy, the Milky Way is located. Lanikea, which in Hawaiian means ‘immeasurable heaven’ contain 100,000 galaxies and has the mass of one hundred quadrillion suns.
