The galaxy M87, found in the Virgo constellation, became famous in 2019 when scientists took the first-ever picture of a black hole at its center using the Event Horizon Telescope. Recently, a research team noticed a huge gamma-ray flare coming from it, which is much bigger than the black hole itself—by seven orders of magnitude, or tens of millions of times larger. This type of flare, which hasn't been seen in more than ten years, can help researchers understand how particles like electrons and positrons are sped up in the extreme conditions near black holes.
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 galaxy's center. An international research team has now observed a teraelectronvolt gamma-ray flare seven orders of magnitude -- tens of millions of times -- larger than the event horizon, or surface of the black hole itself. A flare of this intensity -- which has not been observed in over a decade -- can offer crucial insights into how particles, such as electrons and positrons, are accelerated in the extreme environments near black holes. rewrite it in simple word
