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.

X-ray emission from massive stars

Massive young stars are known to emit strong X-rays. Unlike the X-ray emission from lower mass stars, however, which arises in stellar photospheres, the X-rays from massive stars are thought to result from powerful shocks. ...

Revisiting the Veil Nebula

Deriving its name from its delicate, draped filamentary structures, the beautiful Veil Nebula is one of the best-known supernova remnants. It formed from the violent death of a star twenty times the mass of the Sun that exploded ...
