The empty regions between galaxies which we believed to be frigid and vacant for many years now have new evidence from modern telescopes that show these dark spaces contain active movements. The newly discovered information about the universe’s structure and galaxy survival has completely transformed our previous knowledge.
The “Galactic Web” of Gas
Scientists have finally captured images of the “Cosmic Web,” a vast network of thin filaments made of hydrogen gas. The threads of this system serve as a cosmic roadway which links various galaxies that exist across distances of several million light-years. The gas serves as the essential resource which enables galaxies to generate fresh stellar formations.
Rogue Stars Drifting in the Dark
The people of our past believed that stars existed only within the confines of galaxies. Astronomers have discovered “rogue stars” which move through the vast regions of space that exist between galaxies. The stars originated from their home galaxies after they experienced intense collisions and dangerous encounters with black holes.
Ghostly Dark Galaxies
Researchers have located “Ultra-Diffuse Galaxies” that are nearly invisible. They have the same dimensions as our Milky Way galaxy and possess almost zero stellar content. The objects remain intact because mysterious dark matter functions as their binding force while they resemble the spectral form of incomplete galaxy structures.
Massive Halos of Heavy Metals
The space outside our galaxy contains more elements than just hydrogen because everything in space has elements known as heavy elements which include oxygen carbon and iron. Massive stars produce metals which they create inside their cores. Supernova explosions expel these metals into space through their powerful sneeze effect. The resulting chemical halo surrounds the Milky Way.
Wandering Black Holes
The latest evidence indicates that enormous black holes have “become wandering outcasts” who travel between the galaxies. The black holes were thrown out of their galaxy centers during the galaxy merger process and they now move through space at speeds exceeding a million miles per hour.
Satellite “Dwarf” Galaxies
Scientists keep finding tiny “hidden” galaxies orbiting our own. The faintness of these dwarf galaxies made them invisible during previous observations. The Milky Way galactic growth process can be understood through our research of these smaller galaxies.
Intergalactic Magnetic Fields
Space does not have a state of magnetic neutrality. Astronomers have found faint but vast magnetic fields stretching across the void. The fields determine how cosmic rays move through space and how the first stars came into existence.
Mega-Clouds of Hot Plasma
The intergalactic space that exists between galaxy clusters contains plasma which exists in a state known as “warm-hot”. The gas exists in a state where its density approaches that of a vacuum yet its temperature remains elevated enough to produce X-ray emissions. The entire universe possesses more normal matter than all its stars and planets combined according to the plasma.
Bubbles of Nothingness
Scientists discovered “Great Voids” which are wide space regions that extend for hundreds of millions of light-years and hold almost nothing. Empty bubbles which exist in the universe create a force that pushes galaxies apart while scientists use this method to determine the expansion rate of the cosmos.
