The Virgo Supercluster is a vast and mysterious structure that contains thousands of galaxies, including our Milky Way Galaxy. Scientists have been studying it for decades, but many mysteries still remain. In this article, we will uncover some of the most enigmatic secrets of our cosmic abode.
The Great Attractor: A Mysterious Force
One of the biggest mysteries surrounding the Virgo Supercluster is an incredibly massive gravitational anomaly known as The Great Attractor. This force lies beyond the Milky Way Galaxy and pulls towards it many galaxies at high speeds.
Despite its name, little is known about this attraction or what causes it. Some scientists speculate that it may be a supermassive black hole or dark matter cluster.
Dark Matter: Its Role in Shaping The Structure
Dark matter makes up about 27% of all matter in our universe but cannot be directly observed as it does not interact with light or other forms of electromagnetic radiation. However, its presence can be detected through its gravitational effects on visible matter.
It is believed that dark matter plays an essential role in shaping the structure and evolution of large-scale structures like galaxy clusters within The Virgo Supercluster.
Dwarf Galaxies: A Hidden Population
Dwarf galaxies are small galaxies with only a few million stars compared to billions found in larger ones like our Milky Way Galaxy. They are often overlooked due to their small size but play a significant role within The Virgo Supercluster.
Scientists have discovered hundreds of dwarf galaxies within this supercluster - some even orbiting larger ones such as Andromeda Galaxy - making them crucial to understanding how galaxy clusters form and evolve over time.
Galactic Cannibalism: When Galaxies Merge
Galactic cannibalism occurs when one galaxy absorbs another entirely by pulling apart stars, gas clouds and planets while leaving no trace of the consumed galaxy behind.
It is believed that galactic cannibalism has played a significant role in shaping the structure and evolution of The Virgo Supercluster over time. As galaxies merge, they release huge amounts of energy, leading to the formation of new stars and triggering massive bursts of star formation.
Supermassive Black Holes: The Heart Of Galaxies
Supermassive black holes are incredibly dense regions at the centers of galaxies that have mass equivalent to billions or trillions times that of our sun. They are responsible for powering quasars, which are among the brightest objects in our universe.
Within The Virgo Supercluster lies several supermassive black holes such as at the center of M87 galaxy located within its core. Scientists believe these black holes play a crucial role in regulating star formation and galaxy growth within this supercluster.
The History of the Virgo Supercluster: The Fascinating Story of Our Ever-Expanding Galactic Neighborhood
The Virgo Supercluster has a long and fascinating history that dates back billions of years. From its formation to its present-day structure, this galactic neighborhood has been shaped by numerous events and forces. In this article, we will explore the history of The Virgo Supercluster.
Formation: A Cosmic Collision
The formation of The Virgo Supercluster is believed to have started around 13 billion years ago following a massive cosmic collision event between two smaller clusters. This collision caused vast amounts of gas and dust to be thrown together, leading to the formation of new stars and galaxies.
Over time, these collisions continued to occur until eventually forming the massive supercluster that we know today.
Expansion: Growing Over Time
The expansion rate for Virgo is estimated at about 1 million miles per hour! It was discovered in 1912 by astronomer Vesto Slipher when he noticed an unusual redshift in distant galaxies which suggested they were moving away from us at incredible speeds.
Since then, it has been determined that our universe is still expanding even today, which means that The Virgo Supercluster continues to grow larger every day!
Discovery: Edwin Hubble's Contribution
Edwin Hubble's contribution can't go unnoticed when talking about discovering our local group in space! He was one of the first astronomers who observed many galaxies beyond ours using telescopes from Mount Wilson Observatory in California.
In 1930s Edwin Hubble made several observations on distance measurements between celestial objects including those within our galaxy as well as neighboring ones eventually allowing him to discover what we now call 'The Virgo Cluster'.
He also discovered something else - redshifts - which helped explain why some distant objects appeared redder than others; it was due not only their distance but also their velocity away from us! This discovery allowed for the first detailed mapping of The Virgo Supercluster's structure.
Discovering New Galaxies: Advancements In Technology
In recent years, advancements in technology have allowed astronomers to discover new galaxies within The Virgo Supercluster. Using telescopes, satellite observatories and computer simulations, scientists are continuing to uncover more information regarding this vast cosmic structure.
One significant discovery was the detection of multiple galaxies inside a large void region called 'The Local Void' which lies on the outskirts of this supercluster. These observations have led scientists to believe that there could be even more undiscovered galaxies waiting to be found within our local group!
