“Big Baby” Galaxies Formed Very Differently Than We Assumed
- Year Discovered: 2021
- Location: Eridanus Constellation
Spitzer yet again managed to come across some old universal content. The telescope found the earliest-forming galaxies ever studied. Light from those galaxies took billions of years to reach Earth. This is cool to see too, as scientists are seeing the galaxies as they were those billions of years ago. Naturally, they are over 13 billion years old, which is about 400 million years after the initial birth of the universe. To be able to see these baby galaxies’ form is incredible for science.
