What is the nature of dark energy, a recently discovered dominant constituent of the universe today? Is expansion-accelerating dark energy an intrinsic property of space-time itself or rather a field ...

Cherenkov Telescope Array Observatory to be world’s largest and provide new insights into high-energy Universe.

An astounding gamma-ray burst, dubbed GRB 221009A, continues to amaze even though it has been more than a year since it was detected. Scientists from Italy have recently published a study that shows ...

"Developed initially for space observations, the Compton Camera has now proven its worth as a tool for addressing complex scientific questions in other domains as well." When you purchase through ...

An international team of scientists has just demonstrated, for the first time, a stream of particles escaping from a young, massive star cluster in our galaxy by combining data from NASA's ...

Observations of gamma rays, emitted by relativistic jets in a microquasar system, demonstrate the acceleration of electrons by a shock front, reports a new study. The microquasar SS 433 is a binary ...

What can the gamma ray light emitted by the Milky Way Galaxy teach scientists about the existence of dark matter? This is what a recent study published in Physical Review Letters hopes to address as a ...

A group of international researchers has discovered the highest-energy light ever observed from the sun. In a new paper published last week in the journal Physical Review Letters, scientists found the ...

In 2019, the world was mesmerized by the first-ever image of a black hole, courtesy of the Event Horizon Telescope (EHT). The striking image depicted the supermassive black hole at the center of the ...

galaxies. On Tuesday 8 April, Sheila McBreen of University College, Dublin, will tell the UK/Ireland National Astronomy Meeting in Dublin that her analysis of the way gamma-rays were emitted over the ...

Gamma-rays are the highest energy (the shortest wavelength) type of electromagnetic radiation. They are classified as a type of an ionising radiation; with respect to alpha and beta particles they ...

"Maybe there are additional mechanisms generating gamma rays that go beyond the interaction of cosmic rays with the surface of the sun." When you purchase through links on our site, we may earn an ...
