scientist at the University of California , Santa Cruz , have take the first image ever ( on the left ) of the Cosmic Web that binds the Universe together . I use capital because if there ’s a Cosmic Web that connects all Galax urceolata through the Universe , it should be capitalize .
In a research paper published in Nature this Sunday , the stargazer describe how they take the image using the 10 - meter scope at the W. M. Keck Observatory in Hawaii :
This rich epitome ( on the left-hand , above ) shows the nebula ( cyan ) extend across 2 million lightsome - years that was fall upon around the bright quasar UM287 ( at the eye of the image ) . The energetic radiation of the quasar cook the surrounding intergalactic gas glow , reveal the morphology and physical properties of a cosmic web fibril .
According to lead subject area author Sebastiano Cantalupo , the 2 - million - light - year Cosmic World Wide Web fibril “ is a very exceptional object : it ’s Brobdingnagian , at least twice as large as any nebula detected before , and it extends well beyond the astronomical environment of the quasi-stellar radio source . ”
The image confirms the possibility of Cosmic WWW that entangles the Universe itself , a net of threads that is made mostly — about 84 percent — of invisible blue matter :
Computer simulations ( on the rightfulness , above ) suggest that matter in the universe of discourse is distributed in a “ cosmic web ” of filaments , as catch in the persona above from a orotund - scale obscure - issue simulation ( Bolshoi simulation , by Anatoly Klypin and Joel Primack ) . The inset is a zoomed - in , high - resolution image of a smaller part of the cosmic web , 10 million light - years across , from a pretending that admit natural gas as well as dark thing ( credit : S. Cantalupo ) .
The image deal by Cantalupo et al was possible because of the acute radiation of the quasar UM287 which “ like a flashlight , [ can ] illuminate part of the surrounding cosmic web and make a filum of flatulence radiance . ”
This is the first sentence in account that one of these filaments has been abide by , enounce UC Santa Cruz professor of astronomy and astrophysics J. Xavier Prochaska :
This quasar is illuminating diffuse gas on scales well beyond any we ’ve see before , giving us the first picture of extensive gas between galaxies . It provides a fantastic insight into the overall anatomical structure of our universe .
There ’s also an object yell sullen galaxy . Describing the unique image , Cantalupo says that “ the drear galaxies are much denser and smaller part of the cosmic vane . In this raw range of a function , we also see gloomy galax , in addition to the much more diffuse and extended nebula . Some of this flatulence will fall into galax , but most of it will remain diffuse and never form stars . ”
