Astronomers have detected the universe’s largest known cosmological supervoid in the Southern constellation of Eridanus. Spanning some 1.8 billion light years !!!!!!!

(1 Light Years ~ 9 Trillion Kilometer)

It might be the single largest structure ever in the universe, and the only sign of it is nothing – just empty space 1.8 billion light years across. That’s 18,000 times larger than our entire galaxy.

the team remains mainly baffled as to why such an extensive void — in which the “density of galaxies is much lower than in the known universe” — could have actually arisen.

“This supervoid is certainly rare,” Greg Aldering, a cosmologist at Lawrence Berkeley National Lab in California, told Forbes. “Underdense by about 30 percent, it’s not completely empty. But what’s rare is the [spatial] extent of this void itself.”

Perhaps human being describes this void as a void because it is at a different dimension; and cannot describe inside of course in such a situation. Perhaps this void is a place where there are parallel universes; did you ever think about? Here is frequently such beatiful crazy ideas come to my mind:)

  Everything is possible but scientifically there is no evidence of extra dimensions. Many research and experiments are going on but none of them are able to give any sign of extra dimension.
  So presently it is safe to say that it is a void
  But everything is possible in universe

    opps, it was bad my Earthling friend. And if is that so where are these parallels! :))

      Maybe they are because Parallel universes

      These are theories are just awesome !!!
      That why I like space and astronomy .
      Full of unknown things and mysterious.

Just be careful when describing this void and connecting it to the universe! They may just be describing my head 🙂

Nothingness, the final frontier! Is the void God, from which all something springs?

The NASA/ESA Hubble Space Telescope has revisited one of its most iconic and popular images: the Eagle Nebula’s Pillars of Creation. This image shows the pillars as seen in infrared light, allowing it to pierce through obscuring dust and gas and unveil a more unfamiliar — but just as amazing — view of the pillars. In this ethereal view the entire frame is peppered with bright stars and baby stars are revealed being formed within the pillars themselves. The ghostly outlines of the pillars seem much more delicate, and are silhouetted against an eerie blue haze. Hubble also captured the pillars in visible light.
The graceful, winding arms of the majestic spiral galaxy M51 (NGC 5194) appear like a grand spiral staircase sweeping through space. They are actually long lanes of stars and gas laced with dust. This sharpest-ever image, taken in January 2005 with the Advanced Camera for Surveys aboard the NASA/ESA Hubble Space Telescope, illustrates a spiral galaxy's grand design, from its curving spiral arms, where young stars reside, to its yellowish central core, a home of older stars. The galaxy is nicknamed the Whirlpool because of its swirling structure. The Whirlpool's most striking feature is its two curving arms, a hallmark of so-called grand-design spiral galaxies. Many spiral galaxies possess numerous, loosely shaped arms that make their spiral structure less pronounced. These arms serve an important purpose in spiral galaxies. They are star-formation factories, compressing hydrogen gas and creating clusters of new stars. In the Whirlpool, the assembly line begins with the dark clouds of gas on the inner edge, then moves to bright pink star-forming regions, and ends with the brilliant blue star clusters along the outer edge. Some astronomers believe that the Whirlpool's arms are so prominent because of the effects of a close encounter with NGC 5195, the small, yellowish galaxy at the outermost tip of one of the Whirlpool's arms. At first glance, the compact galaxy appears to be tugging on the arm. Hubble's clear view, however, shows that NGC 5195 is passing behind the Whirlpool. The small galaxy has been gliding past the Whirlpool for hundreds of millions of years. As NGC 5195 drifts by, its gravitational muscle pumps up waves within the Whirlpool's pancake-shaped disk. The waves are like ripples in a pond generated when a rock is thrown in the water. When the waves pass through orbiting gas clouds within the disk, they squeeze the gaseous material along each arm's inner edge. The dark dusty material looks like gathering storm clouds. These dense clouds collapse, creati
NASA/ESA Hubble Space Telescope has trained its razor-sharp eye on one of the universe's most stately and photogenic galaxies, the Sombrero galaxy, Messier 104 (M104). The galaxy's hallmark is a brilliant white, bulbous core encircled by the thick dust lanes comprising the spiral structure of the galaxy. As seen from Earth, the galaxy is tilted nearly edge-on. We view it from just six degrees north of its equatorial plane. This brilliant galaxy was named the Sombrero because of its resemblance to the broad rim and high-topped Mexican hat. At a relatively bright magnitude of +8, M104 is just beyond the limit of naked-eye visibility and is easily seen through small telescopes. The Sombrero lies at the southern edge of the rich Virgo cluster of galaxies and is one of the most massive objects in that group, equivalent to 800 billion suns. The galaxy is 50,000 light-years across and is located 28 million light-years from Earth.

This image of a pair of interacting galaxies called Arp 273 was released to celebrate the 21st anniversary of the launch of the NASA/ESA Hubble Space Telescope. The distorted shape of the larger of the two galaxies shows signs of tidal interactions with the smaller of the two. It is thought that the smaller galaxy has actually passed through the larger one.
This image shows the centre of the globular cluster Messier 22, also known as M22, as observed by the NASA/ESA Hubble Space Telescope. Globular clusters are spherical collections of densely packed stars, relics of the early years of the Universe, with ages of typically 12 to 13 billion years. This is very old considering that the Universe is only 13.8 billion years old. Messier 22 is one of about 150 globular clusters in the Milky Way and at just 10 000 light-years away it is also one of the closest to Earth. It was discovered in 1665 by Abraham Ihle, making it one of the first globulars ever to be discovered. This is not so surprising as it is one of the brightest globular clusters visible from the northern hemisphere, located in the constellation of Sagittarius, close to the Galactic Bulge — the dense mass of stars at the centre of the Milky Way. The cluster has a diameter of about 70 light-years and, when looking from Earth, appears to take up a patch of sky the size of the full Moon. Despite its relative proximity to us, the light from the stars in the cluster is not as bright as it should be as it is dimmed by dust and gas located between us and the cluster. As they are leftovers from the early Universe, globular clusters are popular study objects for astronomers. M22 in particular has fascinating additional features: six planet-sized objects that are not orbiting a star have been detected in the cluster, it seems to host two black holes, and the cluster is one of only three ever found to host a planetary nebula — a short-lived gaseous shells ejected by massive stars at the ends of their lives.
This handout artist's concept provided by NASA/JPL shows the Comet Siding Spring approaching Mars, shown with NASAs orbiters preparing to make science observations of this unique encounter. A pristine distant comet created a once-in-eight-million-year fireworks show on Mars and no humans were there to witness it. But new NASA data from satellites circling Mars released Friday shows that on Oct. 19 when Comet Siding Spring skimmed the red planet, tons of comet dust bombarded the Martian sky with thousands of fireballs an hour. It warped the Martian atmosphere leaving all sorts of metals and an eerie yellow afterglow. (AP Photo/NASA/JPL)
