Apparently galaxies may have evolved during their lifetimes a bit differently than we had previously thought, according to this study:

A team of international scientists, led by astronomers from Cardiff University’s School of Physics and Astronomy, has shown for the first time that galaxies can change their structure over the course of their lifetime.

By observing the sky as it is today, and peering back in time using the Hubble and Herschel telescopes, the team have shown that a large proportion of galaxies have undergone a major ‘metamorphosis’ since they were initially formed after the Big Bang.

(Just a note a lot of astrophysicists are now saying the big bang theory may be incorrect)

Let’s find out what this means and check out a video on galaxy formation on the next page
