Indian Scientists Discover Ancient Spiral Galaxy Alaknanda

Indian scientists from the National Centre for Radio Astrophysics (NCRA-TIFR) in Pune, using data from NASA’s James Webb Space Telescope (JWST), have identified a remarkable galaxy named Alaknanda. Unlike most early galaxies, which were chaotic and irregular, Alaknanda displays a well-defined spiral structure similar to our Milky Way. This finding is significant because spiral galaxies were believed to require at least three billion years to develop such orderly arms, yet Alaknanda achieved this far earlier in cosmic history.  

 

Key highlights from the announcement include  

This breakthrough not only reshapes scientific understanding of galaxy evolution but also underscores India’s growing role in cutting-edge astronomical research. By revealing that mature spiral galaxies could exist much earlier than previously thought, Alaknanda opens new avenues for studying the dynamics of cosmic structures and the forces shaping the universe.
