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 ...

"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 ...

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 ...

The long-awaited detection of gravitational waves has opened up a whole new world of astronomy. One of the key efforts is now ...

"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 ...

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 ...

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.

This strange finding suggests an intricate interrelationship between the immediate surrounding environment of a black hole and its emitting high-energy radiation. Multi-wavelength investigations by ...

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 ...
