Much of the gaseous mass of the universe is bound up in a tangled web of cosmic filaments that stretch for hundreds of millions of light-years, according to a new supercomputer study. The study indicated a significant portion of the gas is in the filaments -- which connect galaxy clusters -- hidden from direct observation in enormous gas clouds in intergalactic space known as the Warm-Hot Interga... read full post picked by AutumnLotus 10 months ago

Two Canadian astronomers think there is a good reason dark matter, a mysterious substance thought to make up the bulk of matter in the universe, has never been directly detected: It doesn't exist. picked by AutumnLotus 12 months ago

About 70 percent is dark energy, and around 22 percent of the universe is made up of dark matter. Dark matter makes up a substantial part of the universe. Knowing what it is would answer a crucial question about the universe as a whole. picked by braveheart 2 years ago

Not only has a large chunk of the universe thought to have been found in 2002 apparently gone missing again but it is taking some friends with it. The new calculations might leave the mass of the universe as much as ten to 20 percent lighter than previously calculated. picked by AutumnLotus 11 months ago

Miss Universe 2007, the 56th Miss Universe pageant, will be held today(on 28/05/2007) at the National Auditorium in Mexico City, Mexico. 77 contestants compete for the title. Here are the videos and swimsuit photos of all the contestants. Enjoy! picked by SunSeven 1 year ago

It's an ambitious task, recreating the universe in a bucket. But if it is successful, the experiment could help solve the twin puzzles of why we’re made of matter rather than antimatter and where the huge magnetic fields that span galaxies come from. picked by AutumnLotus 8 months ago

Astronomers have found an enormous hole in the Universe, nearly a billion light-years across, empty of both normal matter such as stars, galaxies, and gas, and the mysterious, unseen "dark matter." While earlier studies have shown holes, or voids, in the large-scale structure of the Universe, this new discovery dwarfs them all. picked by AutumnLotus 1 year ago

Astronomers are using the NASA/ESA Hubble Space Telescope to dissect one of the largest structures in the Universe as part of a quest to understand the violent lives of galaxies. Hubble is providing indirect evidence of unseen dark matter tugging on galaxies in the crowded, rough-and-tumble environment of a massive supercluster of hundreds of galaxies. picked by AutumnLotus 9 months ago

The identity of the mysterious dark matter thought to pervade the universe has eluded astrophysicists for decades. Now, for the first time a team hopes to look inside the sun for one of the prime candidates. picked by AutumnLotus 4 months ago

Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can't be explained by any of the known gravitational forces in the observable universe. Astronomers are calling the phenomenon "dark flow." picked by AutumnLotus 3 weeks ago

Astronomers may have unwittingly hastened the end of the Universe by simply looking at it, according to a theory reported. The novel idea is being aired by two US physicists, who attack the notion that the universe, believed to have been created in the "Big Bang'' some 13.7 billion years ago, will go on, well, forever. picked by AutumnLotus 11 months ago

Stars always evolve in the universe in large groups, known as clusters. Astronomers distinguish these formations by their age and size. The question of how star clusters are created from interstellar gas clouds and why they then develop in different ways has now been answered by researchers at the Argelander Institute for Astronomy at the University of Bonn with the aid of computer simulations. picked by AutumnLotus 12 months ago

Small, ultrafaint "hobbit" galaxies recently found hovering around our Milky Way are comprised almost entirely of dark matter, a new study confirms. Dark matter is a mysterious substance scientists think accounts for most of the mass in the universe but that is invisible to current instruments. picked by AutumnLotus 1 year ago

In a cosmic battle of sorts taking place in the centers of galaxies, stellar forces muscle up and kick out brewing invisible matter. The result, finds a new study, evens out the amount of invisible matter held in galactic cores, resolving a cosmological puzzle. picked by AutumnLotus 10 months ago

New research from the Niels Bohr Institute presents new information that adds another piece of knowledge to the jigsaw puzzle of the dark mystery of the universe – dark matter. picked by AutumnLotus 1 year ago

Huge filaments of dark matter have been detected in a survey of thousands of distant galaxies. The discovery supports the idea that dark matter drove the formation of galaxies and larger cosmic structures and resolves a discrepancy in previous studies about how much dark matter the universe contains. picked by AutumnLotus 8 months ago

Recently, two groups of astronomers were able to see two classes of unique galaxies from the early universe. One group glimpsed galaxies that looked old even when the universe was young, suggesting they must have been some of the first galaxies to form after the birth of the universe. The other group found galaxies dating from the strongest burst of star formation in the universe. picked by AutumnLotus 6 months ago

Astronomers have used ESO’s Very Large Telescope to measure the distribution and motions of thousands of galaxies in the distant Universe. This opens fascinating perspectives to better understand what drives the acceleration of the cosmic expansion and sheds new light on the mysterious dark energy that is thought to permeate the Universe. picked by AutumnLotus 9 months ago
