Space scientists have been working long to discover other universes. Many researchers and studies have been conducted so far and are still going on to understand the reasons, which led to the formation of Milky Way and nearby constellation. Till date it has been accepted that Milky Way and its orbiting companion Andromeda are the leading components in a flock of galaxies known as the Local Group, which is nearly 3 million light years away.
Lately, a research has open up new avenues with respect to new galaxies within 35-million light years of the Earth. Arrangement of galaxies within a radius of 20 million light years is in the form of a ‘Local Sheet’ with a thickness of 1.5 million light years. Twelve huge galaxies envelop both, the Milky Way and the Andromeda constellation, while the arrangement is in the form of a ring of nearly 24-million light years.
Researchers have termed the flock as “Council of Giants”. The local group acts as a gravitational judge and hence, limits the Council’s range of influence.
As per the space scientists, 12 of the total 14 galaxies in the Local Sheet have spiral structures with flattened disks. It is in these flattened disks that the stars are formed. The remaining two galaxies have elliptical arrangement with stellar bulk being consumed or sifted away long back. These two ellipticals occupy positions at the either sides of the Council of Giants.
It is assumed that during the earlier phase of evolution, winds might have been instrumental in shepherding the gas towards the Local Group from the ellipticals thus, helping it creating disks for Milky Way and Andromeda.
Lead researcher McCall claims that the galaxies must be rotating within the Council in a similar way as a screw would spin on either side when stubbed in a piece of wood. Milky Way and Andromeda are responsible for showering the gravitational torques, which is one of the major factor this spatial alignment.
The Council has identified its own periphery, this interesting phenomena has instigated researchers into the insights, which has led to the formation of Milky Way. Further, it has been observed that only a minor density enhancement of matter in the universe has been instrumental in creating the Local Group.
The spatial dark matter must have created a form of a sheet that might have led to the formation of such a methodical array of the Local Sheet and its Council concluded the researchers.
