SPT0418-47

SPT0418-47 is a young, extremely distant galaxy, discovered in 2020, surprisingly similar to the Milky Way, and looks like it was when the universe was only 1.4 billion years old.[1][2] It is surprisingly non-chaotic and contradicts the theory that all galaxies in the early Universe were turbulent and unstable.[2] It is located at a distance of about twelve billion light years from the Milky Way, where the planet Earth is located.[2] The circular image shown below is due to the gravity of a different galaxy (between the Earth and the galaxy SPT0418-47) which focused the light from SPT0418-47 creating through gravitational lensing the circular image. Computer modeling was then carried out revealing a rotating disk and central bulge, as in the right image below (Science, page 751, August 14 2020, Volume 369, Issue 6505).
