A study provides crucial clues about how cosmic objects send accelerated particles through space. Jets coming from quasars and supernovae can send dangerous cosmic rays that hit Earth. For the first ...

The European Space Agency’s (ESA) Cluster satellites have discovered that cosmic particle accelerators are more efficient than previously thought. The discovery has revealed the initial stages of ...

Astronomers have found a vast loop-like structure, 20 light years across, adjacent to the most massive star-forming region known in our galaxy. The loop, which was observed in X-ray wavelengths, is 15 ...

When massive stars reach the end of their life cycles, they often explode in dramatic cosmic events called supernovae. These powerful explosions not only scatter elements crucial for forming new stars ...

Researchers have been mapping the centre of our galaxy in very-high-energy gamma rays using these telescopes – the most sensitive of their kind – for over 10 years. The results were published in the ...

Laser plasma device could be light enough to be used on the field.

Plasma is a state of matter that emerges when a gas is heated to sufficiently high temperatures, prompting some electrons to become free from atoms. This state of matter has been the focus of many ...

Composite image of the Tycho Supernova remnant. Shock waves from such explosive events are believed to be the main drivers behind cosmic rays. Scientists have come a step closer to understanding how ...

A constant shower of subatomic particles rains down from space. A hundred years ago, this “cosmic radiation” was discovered by the Austrian physicist Victor Franz Hess. Among other things, the ...

Researchers have detected an extremely energetic cosmic ray from an unknown source in the universe. The detection of a cosmic ray with such high energy is "exceedingly rare" and the latest discovery, ...
