This post explores supermassive black holes (SMBHs). It will discuss the tools that astronomers use to find these objects before exploring their link with active galactic nuclei (AGN). It will be discovered that SMBHs provide the energy source that produces AGN. The phenomena we observe from these objects are described [...]
Look up at the night sky, and you might think each twinkling point of light is a single star, much like our Sun. Interestingly, this is not true. We find that the vast majority of stars are part of binary or multiple-star systems. To put a number on it, 85% [...]
