Astronomers have discovered one of the largest spinning structures ever detected in the Universe, a ring of galaxies spanning over 5 billion light-years across and rotating at speeds of over 3 billion kilometers per hour. This enormous astronomical structure, named the “Cosmic Carousel”, is believed to be one of the Universe’s largest known rotating structures.
The discovery was made by a team of international researchers led by the Leibniz Institute for Astrophysics Potsdam (AIP). The structure was found in the constellation of Perseus, and consists of a ring of nine galaxies. These galaxies are gravitationally bound and appear to rotate in unison around a common center, in a similar manner to the rotation of planets around the Sun.
The rotation speed of the structure, measured in excess of 3 billion kilometers per hour, is a significant finding. It suggests the presence of an enormous amount of unseen mass, or “dark matter”, causing such rapid rotation. This is a significant finding as it provides more evidence of the existence of dark matter, a theoretical substance that makes up about 85% of the Universe’s mass but has never been directly observed.
The Cosmic Carousel was identified using data from the Sloan Digital Sky Survey (SDSS), a massive astronomical survey that has been mapping the Universe in three dimensions for over two decades. The SDSS uses a dedicated 2.5-meter telescope located at Apache Point Observatory in New Mexico, USA, to collect its data.
The discovery of the Cosmic Carousel has implications for our understanding of galaxy formation and the role of dark matter in the Universe. It is believed that such large-scale structures formed early in the Universe’s history, as a result of gravitational interactions between galaxies and dark matter. These structures are thought to influence the distribution and evolution of galaxies in the Universe.
The researchers plan to continue studying the Cosmic Carousel to better understand its structure and dynamics. They also hope to find more similar structures in the Universe, which could provide further insights into the role of dark matter and the formation and evolution of galaxies. This discovery is a testament to the capabilities of modern astronomical surveys and the potential for future discoveries in our ever-expanding Universe.
