Indian researchers have discovered an ancient and fully formed spiral galaxy named Galaxy Alaknanda, and this finding is surprising the scientific community. The galaxy was detected with the help of the James Webb Space Telescope (JWST). What makes this discovery special is that Galaxy Alaknanda looks like a mature spiral galaxy even though it formed when the universe was extremely young.

A Fully Developed Galaxy in the Early Universe

Galaxy Alaknanda formed about 12 billion years ago, which means it existed when the universe was only 1.5 billion years old. During this period, most galaxies were still small, chaotic, and irregular. However, Alaknanda shows a clear and organised spiral shape, similar to our own Milky Way.

Researchers found two neat and symmetrical spiral arms extending out from a central disk. These arms wrap around a bright core, showing that the galaxy was already well-structured at an early stage of the universe.

Indian Researchers Play a Key Role

This discovery was made by scientists from the National Centre for Radio Astrophysics (NCRA), Tata Institute of Fundamental Research (TIFR), Pune. Their analysis shows that Galaxy Alaknanda has all the features of a classic spiral galaxy. One noticeable feature is the presence of “beads-on-a-string” — a pattern of star clusters often found in developed spiral galaxies.

The galaxy is estimated to be nearly 30,000 light-years wide and contains about 10 billion stars. Star formation in Alaknanda is happening much faster than in the Milky Way. In fact, stars are being formed 20–30 times faster, indicating a very active and dynamic environment.

Impact on Current Galaxy Formation Theories

Scientists have long believed that spiral galaxies take billions of years to form stable and organised shapes. Most models say that galaxies need to slowly build mass over a long period before forming spiral arms.

However, the early maturity of Galaxy Alaknanda challenges this belief. Its massive size — about 10 billion times the mass of the Sun — grew in just a few hundred million years, which is much quicker than earlier theories suggested. This means galaxy formation in the early universe may have been faster and more organised than scientists previously thought.

Important Takeaways

Galaxy Alaknanda formed when the universe was only 10% of its current age.
It is located about 12 billion light-years away from Earth.
It shows a grand design spiral structure, similar to the Milky Way.
Star formation in Alaknanda is 20–30 times faster than in the Milky Way.

What Comes Next?

Astronomers plan to study Galaxy Alaknanda further using the James Webb Space Telescope and the ALMA observatory in Chile. These advanced tools will help scientists measure its star composition, dust content, and growth rate more accurately.

This discovery adds to increasing evidence that large spiral galaxies were formed much earlier in the universe than expected. Galaxy Alaknanda is helping researchers rethink how quickly cosmic structures formed after the Big Bang.
