By chance an incredible new discovery has been made that could change everything we know about black holes, physics and the universe.This was the first time I saw him throw up and spit on his buttocks.
In 2018, astronomers detected the bright glow of a star torn apart by a black hole called AT2018hyz. AT2018hyz is a black hole about 20 million times larger than the Sun and 665 million light years away. After nearly three years, the black hole has shown signs of massive activity, spewing unknown matter into space, as if it were throwing up the remains of a devouring star.
This observation was first published in The Astrophysical Journal. We were absolutely blown away, “said Yvette Syndis of the Harvard-Smithsonian Center for Astrophysics, and one of the co-authors of the paper reporting the phenomenon. No one has ever seen anything like it before.”
Street A black hole swallows a star It is about destroying the stars with their immense gravity. This is called a TDE or tidal disturbance event.
A common misconception is that black holes behave like cosmic vacuum cleaners, voraciously sucking up the material around them. In fact, only things that pass through the event horizon, including light, are engulfed and cannot escape, but black holes also eat abundantly. This means that some of the substances in the body are already excreted in powerful jets.
In the TDE portion of the star’s original mass thrown outThis creates a rotating ring of matter (also known as an accretion disk) around the black hole that emits intense X-rays and visible light. Jets are one way astronomers can indirectly infer the existence of black holes. These outflows usually occur shortly after the TDE.
In the first months that AT2018hyz was first discovered, the radio telescopes did not detect any trace of leaking material. According to Cendes, this is true for around 80% of TDEs. So astronomers preferred to spend precious time in the telescope over potentially more interesting things. But last June, Cendes and his group decided to use radio data from the Very Large Array (VLA) to double-check some of the TDEs that have seen no emissions in recent years. This time, we noticed that the AT2018hyz lights up the sky again.
