The most distant twin of the Milky Way ever observed

The most distant twin of the Milky Way ever observed

An international team led by the University of Geneva (UNIGE) has discovered the most distant spiral galaxy candidate known to date. This ultra-massive system existed just one billion years after the Big Bang and already shows a remarkably mature structure, with a central old bulge, a large star-forming disk, and well-defined spiral arms.

The James Webb Space Telescope has found Zhulong, the most distant spiral galaxy candidate and long-lost 'twin' of the Milky Way.

Researchers at the University of Geneva (Unige) have discovered a spiral galaxy, such as our Milky Way, which already had that advanced structure at a time relatively close to the Big Bang, which challenges preconceived ideas about the formation of complex galaxies.The entry Discovering a galaxy very similar to the Milky Way already formed shortly after the Big Bang was first published in Digital Process.

The first publicly released image from NASA's James Webb Space Telescope, taken on July 11, 2022. Since the James Webb Space Telescope began its scientific work, astronomers have seen galaxies that existed more than 13 billion years ago. It was during this period, known as the "Cosmic Dark Ages," that the first stars and galaxies formed between 200 million and 1...
