Scientists have found a trail of a supercluster of galaxies about 10 billion light-years in length. The identification was done in 2013. Astronomers behind this discovery had confirmed that the cluster could be the largest known structure in the universe. Read below to understand what a group of astronomers had to say regarding the aforementioned observation.
A team of researchers fiddled with how thermal conduction in a plasma is suppressed, making galaxy clusters hotter than expected. Magnetic fields direct plasma within a cluster of galaxies. It is in a turbulent state and moves erratically. Using lasers, scientists vaporized plastic films and generated a turbulent and magnetized plasma. The electrons in the plasma rarely collide and follow the tangled magnetic field lines.
This phenomenon suppresses heat conduction, creating patches of hot plasma that cannot escape, leaving the cores of galaxy clusters much hotter than expected. Three-dimensional simulations performed with the FLASH code were used to design the platform and analyze the experimental data. The study provides insight into the complex physical processes within galaxy clusters, the Research suggested, according to a copy published in the journal Science Advances.
Hercules-Corona Borealis
The Great Wall of Hercules-Corona Borealis or the Great Wall is the largest known structure in the observable universe, spanning approximately 10 billion light-years in length (the observable universe is approximately 93 billion light-years in diameter). This massive superstructure is a part of the sky seen in the dataset mapping of gamma-ray bursts (GRBs) found to have an unusually higher concentration of GRBs at a similar distance than the expected mean distribution. It is the largest known formation in the universe and is about twice the size of the previous massive LQG.
