Astronomers at The Australian National University have discovered proof of a vast filament of material that connects our Milky Way galaxy to nearby clusters of galaxies, which are similarly interconnected to the rest of the Universe.
“By examining the positions of ancient groupings of stars, called globular clusters, we found that the clusters form a narrow plane around the Milky Way rather than being scattered across the sky,” said Dr. Stephan Keller of the Research School of Astronomy and Astrophysics at ANU.

The Bolshoi supercomputer simulation, the most accurate and detailed large cosmological simulation run to date, gives physicists and astronomers a powerful new tool for understanding such cosmic mysteries as galaxy formation, dark matter, and dark energy.
The simulation traces the evolution of the large-scale structure of the universe, including the evolution and distribution of the dark matter halos in which galaxies coalesced and grew. Initial studies show good agreement between the simulation's predictions and astronomers' observations.

Quantum logic is quite a new and absolutely fascinating field of physics and might - ultimately - lead to the fabrication of a quantum computer. And it could also aid the search for the "theory of everything" - the missing link between traditional physics and quantum physics. One of the fundamental questions of 21st-century physics is whether fundamental constants possibly vary.

Astronomers have long suspected that the chief contributors to this cosmic X-ray background were dust-swaddled black holes at the centers of active but undetected galaxies. Now, an international team of scientists using data from NASA's Swift satellite confirms the existence of a largely unseen population of black-hole-powered galaxies.

Startling new analysis of data sent back by the SPICAM spectrometer on board ESA's Mars Express spacecraft has revealed for the first time that the planet's atmosphere is supersaturated with water vapor. This surprising discovery has major implications for understanding the Martian water cycle and the historical evolution of the atmosphere.

This leaf-beetle fossil from the fossil pits in Messel, Germany represents the purest of biological colors retrieved from prehistoric Earth. A study led by Yale University paleogeologist Maria McNamara analyzed 10 beetle fossils, ranging from 15 million to 47 million years old, which owe their enduring shades to the phenomenon of structural coloration, which is produced by the interaction of light with nanometer-scale surface geometries.

China successfully launched an experimental craft on Thursday paving the way for its first space station amid a blaze of national pride, bringing the growing Asian power closer to matching the United States and Russia with a long-term manned outpost in space.
The Tiangong 1, or "Heavenly Palace", blasted off from a remote site in the Gobi Desert at 9:16 pm (1316 GMT), adding a high-tech sheen to China's National Day celebrations on Oct. 1.

What if our existence is a holographic projection of another, flat version of you living on a two-dimensional "surface" at the edge of this universe? In other words, are we real, or are we quantum interactions on the edges of the universe - and is that just as real anyway?
Whether we actually live in a hologram is being hotly debated, but it is now becoming clear that looking at phenomena through a holographic lens could be key to solving some of the most perplexing problems in physics, including the physics that reigned before the big bang,what gives particles mass, a theory of quantum gravity.

Three of Titan's major surface features -- dunes, craters and the enigmatic Xanadu -- appear in this radar image above from NASA's Cassini spacecraft. The hazy, bright area at the left that extends to the lower center of the image marks the northwest edge of Xanadu, a continent-sized feature centered near the moon's equator. At upper right is the crater Ksa, first seen by Cassini in 2006. The dark lines running between these two features are linear dunes, similar to sand dunes on Earth in Egypt and Namibia.

In a galactic replay of merging of the Earth's tectonic plates into a massive supercontinent known as Pangea 250 million years ago, the Spitzer Space Telescope caught images of four massive galaxies slamming into each other and kicking up billions of stars like grains of sand! As the largest galactic pileup in the known universe, it will produce a huge offspring.
