Web12 feb. 2024 · A supernova is an event that occurs when a star has ejected enough matter into space to make the star collapse. This creates a massive explosion that can outshine an entire galaxy. However, most people don't know that this is usually where a supernova turns into the nebula it turned into. A nebula is made up of gas and dust in a rotating ... WebMost stellar black holes, however, are very difficult to detect. Judging from the number of stars large enough to produce such black holes, however, scientists estimate that there are as many as ten million to a billion such black holes in the Milky Way alone. On the other end of the size spectrum are the giants known as "supermassive" black ...

WebThe most significant difference between a hypernova and a supernova is that the process of a supernova can create elements as heavy as iron. In contrast, a hypernova can create heavier elements like uranium by accelerating the fusion process. The temperature and pressure must reach extreme measures to create heavier elements than iron.
