NASA's WISE mission sees skies ablaze with blazars

Posted: 12 Apr 2012 04:27 PM PDT

Astronomers are actively hunting a class of supermassive black holes throughout the universe called blazars thanks to data collected by NASA's Wide-field Infrared Survey Explorer (WISE). The mission has revealed more than 200 blazars and has the potential to find thousands more.

First-ever model simulation of the structuring of the observable universe

Posted: 12 Apr 2012 10:30 AM PDT

Astronomers have performed the first-ever computer model simulation of the structuring of the entire observable universe, from the Big Bang to the present day. The simulation has made it possible to follow the evolution of 550 billion particles. This simulation, along with the two additional runs expected by late May 2012, will provide outstanding support for future projects dedicated to the observation and mapping of the universe. These simulations will shed light on the nature of dark energy and its effects on cosmic structure formation, and hence on the distribution of dark matter and galaxies in the universe.

Discovery of the Musket Ball Cluster, a system of colliding galaxy clusters

Posted: 12 Apr 2012 08:37 AM PDT

Using a combination of powerful observatories in space and on the ground, astronomers have observed a violent collision between two galaxy clusters in which so-called normal matter has been wrenched apart from dark matter through a violent collision between two galaxy clusters.

Dusty disc of crushed comets around a nearby star caused by collisions with thousands of comets a day

Astronomers have studied a ring of dust around the nearby star Fomalhaut and have deduced that it is created by the collision of thousands of comets every day.

New frontier: Chips transfer data at light speed

Posted: 12 Apr 2012 07:55 AM PDT

The computer industry is nearing a crisis: microchips  get smaller and faster but they struggle to transfer data at sufficient speeds.  Electrons flowing through standard chip connections are just too slow. Now researchers have shown how chips with built-in lasers which use multiple wavelengths of light could in the future transmit data at terabit speeds.

Workings of nearby planetary system revealed

Posted: 12 Apr 2012 07:55 AM PDT

A new observatory still under construction has given astronomers a major breakthrough in understanding a nearby planetary system and provided valuable clues about how such systems form and evolve. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that planets orbiting the star Fomalhaut must be much smaller than originally thought. This is the first published science result from ALMA in its first period of open observations for astronomers worldwide.

Astronomer finds evidence for record-breaking nine planet system

Posted: 12 Apr 2012 07:55 AM PDT

The planetary system around the star named HD 10180 may have more planets in its orbits than our own solar system. Located 130 light years away, the star is not within reach of foreseeable human space travel, but in astronomical distances, it is still considered to be in the solar neighborhood.

New method for continuous production of carbon nanotubes

Posted: 12 Apr 2012 07:51 AM PDT

A new method is capable of reducing the price of carbon nanotubes from $100 - $700 US to just $15 to $35 US for each gram, much lower than world market prices.

Nanomaterials: Making a bluer light

Posted: 12 Apr 2012 07:51 AM PDT

A new design for nanoparticles that absorb low-energy light and emit high-energy light may find use in biological imaging.

Nanomaterials: Surrounding effects

Posted: 12 Apr 2012 07:50 AM PDT

The dissipation of energy from a vibrating gold nanoparticle is strongly influenced by the surrounding environment, new research shows.

Novel coding technique holds promise for next-generation computers

Posted: 12 Apr 2012 07:50 AM PDT

A pioneering error correction technique holds promise for the development of next-generation computers.
