Very big, but not infinite as it’s still growing! We can only see 13.8 billion light-years as that’s the approximate age of the galaxy!

Incredibly huge. So huge that scientists use units of “light-years” to describe distances, where one light-year is the distance light travels in 365 days. * According to a few websites, the diameter (one end to the other end) of space is 93 billion light years, and growing.
