Mechanism explains how the most energetic form of light can be produced in areas dominated by bright, young stars In 2002, when astronomers first detected cosmic gamma rays — the most energetic form ...

Cosmic rays, high-energy particles that travel through space, have puzzled scientists for decades. One particular feature of their energy spectrum—the “knee”—has long remained a mystery. Recent ...

Galactic cosmic rays (GCRs) are energetic particles traveling across the Galaxy as high-energy beams, and are a unique probe to explore the astrophysical particle accelerators and the interstellar ...

You might not realize it, but right now, as you're watching this video, you are being absolutely bombarded by waves of energy ...

Dec. 7, 2009 -- A thin rain of charged particles continually bombards our atmosphere from outer space. The mysterious particles were first detected 100 years ago but until 10 years ago when a new type ...

(a)The UHE gamma-ray emission is clearly observed from the W51 complex, which hosts the supernova remnant W51C and star forming region W51B. (b) The “bending” feature around tens TeV indicates the ...

Did you know that the world around us is filled with different types of light waves ? From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action ...

Much astronomical research in the twenty-first century is a study of impermanence. Telescopes probing the full range of the electromagnetic spectrum, from radio waves to γ-rays, are unveiling an ...

NTNU researchers may have found the answer to one of the big, unanswered questions in physics. The universe is full of different types of radiation and particles that can be observed here on Earth.

One of the landmark discoveries of 19 th century physics was the realisation that electricity, magnetism and light are all connected. Experiments had already shown that the movement of electrical ...
