2022-02-04 – The black holes in space with Sarah Gallagher. A black hole is created after the death of a very massive star. In this video, learn more about black holes with Sarah Gallagher, astrophysicist and Science Advisor to the President of the Canadian Space Agency.
A black hole is a region of space having a gravitational field so intense that no matter or radiation can escape. A black hole is created after the death of a very massive star. The core of the star collapses in on itself, causing a supernova – a massive explosion of the star’s outer layers. All of the former star’s matter is then concentrated into a single tiny point (known as a singularity). The gravity of a black hole is so strong that nothing – not even light – can escape its pull.
