The Universe in Formation. Hubble Sees 6 Examples of Merging Galaxies

Audio narration by the author is available above

10 billion years ago, galaxies of the Universe were ablaze with the light of newly forming stars. This epic phase of history is known as  “Cosmic Noon” – the height of all star creation. Galaxies like our Milky Way aren’t creating stars at nearly the rates they were in the ancient past. However, there is a time when galaxies in the present can explode with star formation – when they collide with each other. This recently published collage of merging galaxies by the Hubble HiPEEC survey (Hubble imaging Probe of Extreme Environments and Clusters) highlights six of these collisions which help us understand star formation in the early Universe.
