What do you think the cosmos looks like if you go beyondthe limits of not only the solar system, but also the local group of galaxies? According to researchers, having gone far beyond the boundaries of our cosmic home, you can see the voids - outer space devoid of galaxies, stars and even atoms, and only countless thin threads of any length and size will be visible between these dead points. The Milky Way, the Andromeda galaxy and the Local Group of galaxies are only a few pixels in this incomprehensibly vast structure, which astronomers call the "cosmic web".
What is known about the cosmic web?
We recently told you about the secrets of spacecobwebs. Today, most of the data about it is based on computer simulations and conclusions of experts. But now, an international group of researchers for the first time saw two gas lines connecting many galaxies in a void. Although the researchers' map covers only a tiny stretch of the massive web, it confirms that modern science is on the right track — the cosmic web seems to play a major role in how galaxies grow.

Supercluster galactic filamentsgalaxies form a complex, interconnected structure that connects the galaxies with each other. However, it is difficult to detect these threads. Michele Fumagalli from Durham University and his colleagues studied the region of the sky in which the proto-cluster of galaxies is located - the region where a large group of galaxies begins to gather. The galaxies inside the cluster emit ultraviolet light, as a result of which new stars form inside or due to foaming areas around supermassive black holes in the centers of galaxies. The filaments of gas absorb this light and emit it. Using the very large telescope of the European Southern Observatory in Chile, astronomers discovered the re-emitted light. According to a study published in the journal Science on October 4, discovered galactic filaments span millions of light years.
Galactic Thread Hunt
Galactic filaments are in the constellation Aquarius12 billion light-years from Earth. Astronomers believe that after the Big Bang 13.8 billion years ago, hydrogen gas collapsed into filaments that extend in space. In areas where the filaments intersected and galaxies formed. The constant flow of gas from galactic filaments allows galaxies to grow. The images obtained during the study confirm this history of the origin of galaxies. According to Hideki Umehat, co-author of the study, an astronomer from the University of Tokyo, galactic filaments were visible only because the light from newly born galaxies was like city lights illuminating clouds passing by.

In addition to its ongoing role in creatinggalaxies, the cosmic web is also a relic of the Big Bang, and each thread is the final result of a certain microscopic pulsation at the time of the birth of the Universe. Thanks to further research, scientists will be able to find out exactly how gravity affected matter, immediately after the Big Bang.

However, until this happens, we offer youcarefully consider the map of galactic filaments discovered by Japanese scientists. Be that as it may, today we can better understand our cosmic environment. We are on a tiny planet orbiting a star that revolves around a galaxy fed by a cosmic gas river that leads somewhere else.
