Indian researchers at Pune’s National Centre for Radio Astrophysics (NCRA-TIFR) have discovered a galaxy that should not exist, not this early, and not in this form. Named Alaknanda, the galaxy is 12 billion years old, formed when the universe itself was only 1.5 billion years old. Yet it resembles a mature Milky Way–style spiral, complete with symmetric arms and a bright central bulge.
PhD researcher Rashi Jain identified the galaxy in James Webb Space Telescope (JWST) data while scanning more than 70,000 celestial objects. Her supervisor, Prof. Yogesh Wadadekar, admitted he struggled to believe the result at first. The structure defies long-held timelines of galaxy formation.
Scientists assumed that stable spiral galaxies required at least 3 billion years to cool, settle, and form organised discs. Alaknanda has shattered that belief by forming 10 billion stars and well-defined spiral arms in a fraction of that time.
Why Alaknanda Changes the Textbooks
The galaxy spans 30,000 light-years, one-third of the Milky Way’s size. It has:
-
Two perfect, symmetric spiral arms
-
A bright central bulge
- Advertisement - -
Rapid star formation at 20–30 times the rate of the Milky Way
-
A classic “beads-on-a-string” pattern along the arms
Such symmetry is extremely rare even today. For it to appear in the early universe was considered almost impossible, until now.
Prof. Wadadekar explained the scale of the shock:
“Alaknanda shows the early Universe assembled large spiral galaxies far faster than expected.”
The discovery forces astronomers to rethink early cooling cycles, mass buildup rates, and the timeline of cosmic structure formation.
India’s Expanding Role in Global Space Science
Alaknanda is not an isolated achievement. It reflects India’s growing presence in global astronomy and space research.
In the last decade:
-
India became one of the few nations to soft-land on the Moon.
-
ISRO launched Aditya-L1, India’s first solar observatory.
-
Indian universities increased their presence in deep-space research through collaborations with JWST, ALMA, and SKA.
-
Indian astronomers now lead international studies on black holes, dark matter, and early galaxies.
Alaknanda adds to this momentum. It shows that India is not only participating in space science, it is shaping the field.
The naming of the galaxy after the Alaknanda river, sister to the Mandakini (Sanskrit name for the Milky Way), blends scientific excellence with cultural continuity. India’s rise in space is not borrowed; it is rooted.
A Discovery That Rewrites the Universe
Alaknanda’s existence challenges the belief that early galaxies were small, chaotic, and unstable. Instead, it reveals that the young universe was capable of rapid organisation and large-scale structure.
Indian scientists are now seeking more time on JWST and ALMA to study Alaknanda’s chemistry, star formation, and evolution. Their work will determine whether Alaknanda is an exception or a sign that many early galaxies were far more organised than expected.
Either outcome reshapes cosmology.
India’s scientific footprint in space is widening. Its discoveries are no longer footnotes; they are milestones.
