Second strongest shock wave found in merging galaxy clusters

The discovery by a physics doctoral student at The University of Alabama in Huntsville (UAH) of the second-strongest merger shock in clusters of galaxies ever observed has generated excitement that is opening doors to further ...

How network effects hurt economies

When large-scale economic struggles hit a region, a country, or even a continent, the explanations tend to be big in nature as well.

NASA's IBEX observations pin down interstellar magnetic field

Immediately after its 2008 launch, NASA's Interstellar Boundary Explorer, or IBEX, spotted a curiosity in a thin slice of space: More particles streamed in through a long, skinny swath in the sky than anywhere else. The origin ...

Imaged 'jets' reveal cerium's post-shock inner strength

Recent synchrotron advances and the development of dynamic compression platforms have created the ability to investigate extreme states of matter on short timescales at X-ray beamlines using shock waves generated by impact ...

Runaway stars leave infrared waves in space

Astronomers are finding dozens of the fastest stars in our galaxy with the help of images from NASA's Spitzer Space Telescope and Wide-field Infrared Survey Explorer, or WISE.

Imaging an expanding supernova shell

Supernovae, the explosive deaths of massive stars, are among the most momentous events in the cosmos because they disburse into space all of the chemical elements that were produced inside their progenitor stars, including ...

Cell stress response and fat and obesity gene linked

In one fell swoop, Cornell researchers have discovered mechanisms that control the function of a fat and obesity gene while at the same time answering a long-standing question about how cells respond to stress.
