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

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 ...

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 ...

"We were lucky to detect a gamma-ray flare from M87 during this Event Horizon Telescope's multi-wavelength campaign," said ...

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 ...

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 ...

Radio waves have the longest wavelengths and gamma rays have the shortest wavelengths. Radio waves have the longest wavelengths of all EM waves. Radio waves have wavelengths ranging from thousands ...

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 ...

The team is hoping the gamma ray outburst data will help scientists ... to capture as they are usually only visible in specific wavelengths. "The activity of this supermassive black hole is ...

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 ...
