The Andromeda galaxy is made up of over a trillion stars. All spread across a vast area spanning more than 200,000 light years. But what is going on deep within its core? Because scientists have discovered something strange happening at the very heart of the galaxy. Join me as we look at real images captured by incredible space telescopes such as Hubble of Andromeda's galactic centre! We will find out how Andromeda grew so big, why its core is mysteriously lopsided and what is creating a vast disk of red stars that astronomers from NASA and ESA still do not fully understand today.
