High-energy cosmic beams hit the Earth’s outer atmosphere, which in turn scatters these rays into a shower of particle decays. A team of CERN openlab summer students has used a recent ‘webfest’ event held at CERN to build a distributed network of simple devices to detect particle decays which are not otherwise visible to the naked eye.

Brookhaven National Laboratory is preparing for a new wave of discoveries. PHENIX is in its final runs, but superPHENIX waits in the wings.

Upgrading its PHENIX detector and Relativistic Heavy Ion Collider marks the beginning of an exciting new chapter for BNL and high-energy physics.

NASA spacecraft New Horizons just met up with a rock some three billion miles (5 billion km) out in space — Pluto, formerly known as the ninth planet in our solar system. A meeting nine years in the making, the flyby is producing amazing images and revising our knowledge of the origins of our solar system.

“Solar Superstorms,” is a science documentary showing off the latest computation-enabled research about solar dynamics. Narrated by Benedict Cumberbatch, the 24-minute documentary illustrates what can happen when our closest star erupts. Stunning visualizations from Donna Cox’s team at the US National Center for Supercomputing Applications (NCSA) Advanced Visualization Laboratory tell the story.

 XSEDE15, the fourth annual conference, will showcase the discoveries, innovations, challenges and achievements of those who utilize and support XSEDE resources and services, as well as other digital resources and services throughout the world.

This year's theme is "Scientific advancements enabled by enhanced cyberinfrastructure."

XSEDE15 takes place July 26-30 at the Renaissance St. Louis Grand Hotel in the heart of downtown St. Louis, Missouri.

An international group of astronomers began the Panchromatic Hubble Andromeda Treasury (PHAT) in 2011 to map and study the millions of stars that comprise the Andromeda galaxy. The project has captured the most detailed panoramic images of the galaxy yet seen, revealing that star formation appears to be the same across the universe.

A wheeling Milky Way or dancing aurora borealis inspires awe and broadens perspective when viewed across the chronological scales time-lapse videos afford. The trouble is it takes a lot of time to construct these videos. But in the smartphone age, the power of collected photographs enables a more collaborative method.

iSGTW interviews Jorge Gomes, member of the European Grid Infrastructure (EGI) executive board, ahead of next month’s EGI Conference in Lisbon, Portugal. He explains why it is vital to support research with grid computing, as well as with a range of related IT services. “In order for researchers to be able to collaborate and share data with one another efficiently, the underlying IT infrastructures need to be in place,” says Gomes. “With the amount of data produced by research collaborations growing rapidly, this support is of paramount importance.”

The Large Synoptic Survey Telescope will provide an unprecedented look into the cosmos, and the Dark Energy Science Collaboration is preparing a variety of analyses for the huge data sets it will produce. In anticipation of their needs, Fermilab is developing innovative software tools and approaches.
