Shocked gas in galaxy collisions

Collisions between galaxies, especially ones rich in molecular gas, can trigger bursts of star formation that heat the dust and result in their shining brightly in the infrared. Astronomers think that there is also significant ...

NuSTAR finds new clues to 'chameleon supernova'

"We're made of star stuff," astronomer Carl Sagan famously said. Nuclear reactions that happened in ancient stars generated much of the material that makes up our bodies, our planet and our solar system. When stars explode ...

Researchers dial in to 'thermostat' in Earth's upper atmosphere

A team led by the University of Colorado Boulder has found the mechanism behind the sudden onset of a "natural thermostat" in Earth's upper atmosphere that dramatically cools the air after it has been heated by violent solar ...

NASA finds unusual origins of high-energy electrons

High above the surface, Earth's magnetic field constantly deflects incoming supersonic particles from the sun. These particles are disturbed in regions just outside of Earth's magnetic field - and some are reflected into ...

Ripples in space key to understanding cosmic rays

In a new study researchers at the Swedish Institute of Space Physics have used measurements from NASA's MMS (Magnetospheric MultiScale) satellites to reveal that there are ripples, or surface waves, moving along the surface ...

Microscopic collisions help proteins stay healthy

Studies at The University of Texas Health Science Center at San Antonio are providing basic new understanding about "heat shock proteins," also called "chaperone proteins." These proteins, first identified in cells subjected ...
