US EditionJames Webb telescope spots Milky Way's long-lost 'twin' — and it is 'fundamentally changing our view of the early universe'
- Astronomers using the James Webb Space Telescope discovered a galaxy named Zhělóng, resembling the Milky Way, just 1 billion years after the Big Bang, marking it as the most distant Milky Way 'twin' observed.
- Zhělóng measures about 60,000 light-years across and contains about 100 billion solar masses, comparable to our galaxy's size and mass, as described in the journal Astronomy & Astrophysics.
- The discovery challenges existing cosmological theories, suggesting large galaxies could form much faster than previously thought, according to Mengyuan Xiao from the University of Geneva.
- Researchers plan follow-up observations with the James Webb Space Telescope to learn more about Zhělóng's properties, as stated by the research team.

Milky Way Twin Discovered in the Infant Universe — But It Shouldn’t Even Exist
Scientists have spotted what appears to be a fully-formed spiral galaxy from just 1 billion years after the Big Bang. The post Milky Way Twin Discovered in the Infant Universe — But It Shouldn’t Even Exist appeared first on Study Finds.
JWST discovers most distant and earliest Milky Way 'twin' ever seen: Meet dragon-galaxy Zhúlóng
Astronomers have discovered the most distant and thus earliest spiral galaxy ever seen, using the James Webb Space Telescope (JWST). This "twin" of the Milky Way existed just 1 billion years after the Big Bang, challenging our theories of galactic evolution. Previously, it was believed that galaxies like ours would take billions of years to form distinct features like spiral arms, vast star-forming disks, and central bulges of densely packed sta…
James Webb telescope spots Milky Way's long-lost 'twin' — and it is 'fundamentally changing our view of the early universe'
The James Webb Space Telescope has discovered Zhúlóng, a candidate for the most distant spiral galaxy in the universe. The perplexing Milky Way 'twin' dates to 1 billion years after the Big Bang, and appears too big to explain.
