There is a gamma-ray lighthouse shining from the edge of our universe. Astronomers have discovered it using ESA’s orbiting gamma-ray observatory, Integral. Now, they must work hard to understand it.

A new method to exploit Gamma-Ray Bursts (GRBs), the most energetic explosions in the universe, as independent measurements of the Universe’s expansion rate has been discovered in optical wavelength.

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 ...

Light curve of the gamma-ray flare (bottom) and collection of quasi-simulated images of the M87 jet (top) at various scales obtained in radio and X-ray during the 2018 campaign. The instrument, the ...

A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it changed Earth’s atmosphere, according to scientists. Gamma rays are 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 ...

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly ...

The pulsar Vela rests a thousand light years away from Earth in a tattered cloud of gas and dust that used to be the guts of a massive star. These magnetic field of this dense, burned-out corpse of ...
