Galaxies: past and present

Dr Emma Curtis-Lake


Dr Curtis-Lake explained how the James Webb Space Telescope will act as a time machine, allowing us to peer into the early Universe to learn how galaxies first formed and how they evolved.

The first galaxies looked very different to the awe-inspiring shapes that populate the Universe today. We have already glimpsed the messy, turbulent and erratic galaxies populating the toddler stage of the Universe, thanks to the Hubble space telescope’s view distant space. But huge chunks of the picture are still missing and it will take the next great space-based observatory, Webb, to start filling them in.
