The energy also helps the star keep its spherical shape. Hydrogen atoms are converted into helium atoms, and the energy that results from the reaction causes the star to shine. Stars emit heat and light because of nuclear reactions that take place in their cores. On April 10, 2019, a network of radio telescopes called the Event Horizon Telescope (EHT) captured and delivered our first image of a black hole! This significant event opens exciting new paths and fields to explore in the study of black holes.īlack Holes were once massive stars. These scientists can help us better understand the stellar evolution of black holes, which in turn can help us understand the dynamics and mechanics of our universe. Physicists and astronomers have been theorizing and studying black holes for over 200 years. Credits: Event Horizon Telescope Collaboration, European Southern Observatory (ESO) press release, April 2019. In April, 2019, EHT researchers unveiled the first direct visual evidence of the supermassive black hole in the centre of Messier 87 and its shadow. The Event Horizon Telescope (EHT) - a planet-scale array of eight ground-based radio telescopes forged through international collaboration - was designed to capture images of a black hole. When a particularly large star nears the end of its life, it often becomes a black hole.
