JWST Finds a Milky Way Twin Born Shockingly Early in the Universe

JWST finds a Milky Way twin born shockingly early in the Universe

A surprisingly mature spiral galaxy named Alaknanda has been spotted just 1.5 billion years after the Big Bang—far earlier than astronomers believed such well-structured galaxies could form. With sweeping spiral arms, rapid star formation, and an orderly disk resembling our Milky Way, it defies long-held theories about how slowly galaxies should assemble. Thanks to JWST and gravitational lensing, researchers could examine the galaxy in remarkabl…

Indian Scientists Discover Ancient Milky Way-Like Galaxy Alaknanda With Spiral Arms

Indian scientists have discovered an ancient and massive galaxy called Alaknanda. It looks similar to our Milky Way galaxy and is special because it has clear spiral arms, even though it formed when the universe was only 1.5 billion years old.

Pune researchers find massive, grand-design spiral galaxy existing since universe's infancy | Science-Environment

Pune researchers find massive, grand-design spiral galaxy existing since universe's infancy Two researchers from an astrophysics institute in Pune have discovered one of the most distant spiral galaxies ever observed - a massive, well-formed system that existed when the universe was just 1.5 billion years old.The finding adds to growing evidence that the early universe was more evolved than previously assumed, they said.Named 'Alaknanda' after a…

Alaknanda: JWST discovers massive grand-design spiral galaxy from the universe’s infancy

A spiral galaxy, shaped much like our Milky Way, has been found in an era when astronomers believed such well-formed galaxies could not yet exist. Two astronomers from India have identified a remarkably mature galaxy just 1.5 billion years after the Big Bang—a discovery that challenges our understanding of how galaxies form and evolve. NASA’s James Webb Space Telescope (JWST) is a powerful telescope capable of detecting extremely faint light fro…

Indian astronomers discover ‘Alaknanda’ spiral galaxy in early universe

New Delhi: Indian astronomers have discovered a massive spiral galaxy that emerged within 1.5 billion years of the Big Bang. A paper describing the research has been published in Astronomy and Astrophysics. Lead author of the paper Rashi Jain says, “We’re seeing this galaxy as it appeared just 1.5 billion years after the Big Bang. Finding such a well-formed spiral galaxy at this early epoch is quite unexpected —it tells us that sophisticated str…
