Most comprehensive map of the universe yet could pinpoint dark matter

By - April 30, 2015 1 Picture
Astrophysicists from the University of Waterloo have compiled the most comprehensive 3D map of our cosmic surroundings to date. The map describes how ordinary matter is distributed in space up to a distance of about a billion light-years away from us. This survey will help scientists better understand the distribution of dark matter and explain why, to some extent, galaxies are moving erratically with respect to us. Read More

LHC proton-lead collisions may have created new form of matter

By - November 28, 2012 6 Pictures
In September, the Large Hadron Collider (LHC) was being tuned to enable it to study proton-lead nucleus collisions for a data run next year. Eventually it ran and data was collected on the collisions for a period of four hours. When the data was analyzed, it revealed that some particle pairs produced in the collision were traveling in the same direction – a highly unusual situation. Although the data is not sufficient for certainty, the consensus appears to favor this as evidence for production of a color-glass condensate, a new form of exotic matter that has so far only existed as a theory.

World's most powerful X-ray laser recreates conditions at the center of a star

By - January 30, 2012 1 Picture
To say things are really heating up at the US Department of Energy's SLAC National Accelerator Laboratory isn't just a bad pun, it's one hell (sorry) of an understatement. An Oxford-led team used the Stanford-based facility that houses the world's most powerful X-ray laser to create and probe a 2-million-degree Celsius (or about 3.6 million degrees Fahrenheit) piece of matter. The experiment allowed the scientists the closest look yet at what conditions might be like in the heart of the Sun, other stars and planets. Read More

World’s faster supercomputer models origins of the unseen universe

By - October 30, 2009 1 Picture
Scientists have for some time postulated that "dark matter" could partially account for evidence of missing mass in the universe, while the hypothetical form of energy known as "dark energy" is the most popular way to explain recent observations that the universe appears to be expanding at an accelerating rate and accounts for 74 percent of the total mass-energy of the universe according to the standard model of cosmology. To better understand these two mysterious cosmic constituents scientists at the Los Alamos National Laboratory (LANL) are using Roadrunner, the world’s fastest supercomputer, to model one of the largest simulations of the distribution of matter in the universe.

X-ray telescope to shed light on dark energy

By - August 21, 2009 3 Pictures
The German Aerospace Center (DLR) and Russia’s Roskosmos space agency are joining forces to try and shed some light on the poorly understood phenomenon referred to as ‘dark energy’. In 2012 the German 'extended Roentgen Survey with an Imaging Telescope Array'(eROSITA) X-ray telescope will be taken into orbit on board the Russian Spektrum Roentgen Gamma (SRG) satellite to start searching for black holes and dark matter in an attempt to answer why the expansion of the universe is accelerating instead of slowing down.

This battle station is fully operational - the world's largest laser nears completion

Lasers, is there anything they can’t do? If they’re not shooting down UAVs, they’re fighting AIDS or bringing us the next generation of HDTVs. That’s all well and good, but when it comes to lasers there’s none bigger than the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) in California - an instrument capable of delivering 500 trillion watts of power in a 20-nanosecond burst which is now nearing completion. Its myriad uses will include providing fusion data for nuclear weapons simulations, probing the secrets of extrasolar planets and could even lead to the holy grail of energy production - practical fusion energy.

Cosmic Dawn simulation provides insights into the early universe

By - February 18, 2009 3 Pictures
Computational Cosmology – the use of simulations to shed light on astronomical mysteries – has provided scientists with a glimpse of what the universe may have looked like 500 million years after the Big Bang, when the first galaxies were forming in the universe’s “reionization” stage. The images, produced by scientists at Durham University, will provide researchers with key insights into dark matter, which remains frustratingly elusive, despite being first proposed in 1933 and making up an estimated 80% of the universe.
