Below are the words to last weeks listening exercise. In case you could not guess, the answer is a black hole.
“This object is a cosmic body of extremely intense gravity from which nothing, not even light, can escape. It can be formed by the death of a massive star. When such a star has exhausted the internal thermonuclear fuels in its core at the end of its life, the core becomes unstable and gravitationally collapses inward upon itself, and the star’s outer layers are blown away. The crushing weight of constituent matter falling in from all sides compresses the dying star to a point of zero volume and infinite density called the singularity.”
