Galactic Burp In 2018, astronomers took the first-ever picture of a black hole, a fascinating and unprecedented glimpse of an ...

The Event Horizon Telescope, which captured the first image of a black hole, has done it again. The Earth-sized telescope ...

Scientists observed M87’s first gamma-ray flare in a decade, revealing insights into its supermassive black hole and ...

Gamma rays are the highest-energy form of electromagnetic radiation, billions of times more energetic than visible light.

Also known as Virgo A or NGC 4486, M87 is the brightest object in the Virgo cluster of galaxies, the largest gravitationally ...

Previous measurements of the energy spectra of these cosmic rays revealed several unexplained features. In general, the ...

An international team of astronomers has observed extremely rapid bursts of high-energy gamma rays from a distant galaxy, an observation that is challenging how astronomers explain such phenomena.

The jet emerging from M87’s supermassive black hole is tens of millions of times larger than its event horizon. In 2019, the ...

That isn’t the only way to measure gamma radiation, though, and [Alan] has a great circuit to measure even relatively weak radiation sources. It uses a very small photodiode, and draws so little ...

The positioning and the intensity of the gamma ray sources are carefully calculated to ensure that the cancer cells receive enough radiation to kill them whilst the surrounding tissue remains in a ...

This marks the first gamma-ray flaring event observed in this source in over a decade, allowing us to precisely constrain the ...

The galaxy M87, located in the Virgo constellation, provided the first-ever photo of a black hole in 2019, when the Event Horizon Telescope captured an image of the supermassive black hole at the ...
