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

M87, a prominent galaxy in the Virgo cluster, gained fame after the Event Horizon Telescope (EHT) revealed the first image of a black hole in its center. A subsequent study analyzed data from EHT's ...

Gamma rays are much shorter in wavelength than visible light, and carry a lot more energy—so much energy, that here on Earth we typically detect strong gamma-ray bursts only from the detonation ...

Opinions expressed by Forbes Contributors are their own. Jamie Carter is an award-winning reporter who covers the night sky. A massive burst of gamma rays produced by the explosion of a star ...

In order of increasing frequency and decreasing wavelength these are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. Electromagnetic waves ...

"We were lucky to detect a gamma-ray flare from M87 during this Event Horizon Telescope's multi-wavelength campaign," says Giacomo Principe, one of the paper coordinators, a researcher at the ...

Electromagnetic radiation is carried by photons, massless particles that travel at the speed of light (300,000 kilometers per second in a vacuum). Every photon is characterized by wavelength (the ...

Gamma radiation does not consist of particles but as short wavelength, high energy electromagnetic radiation emitted from unstable nuclei. It is normally emitted alongside alpha or beta radiation.

Light curve of the gamma-ray flare (bottom ... The instrument, the wavelength observation range and scale are shown at the top left of each image. Disclaimer: AAAS and EurekAlert!
