A “City of Galaxies” Taking Shape
In a groundbreaking astronomical milestone that connects the natural heritage of Northeast India with the frontiers of space exploration, an international team of scientists has discovered a massive cosmic structure of young galaxies dating back approximately 12.6 billion years. Led by Manipuri astrophysicist Dr. Ronaldo Laishram, the team has officially named this early-stage galaxy cluster the “Loktak Protocluster”, publishing their revolutionary findings in The Astrophysical Journal Letters.
In astronomy, a protocluster is frequently described as a developing “city of galaxies” slowly taking shape under the intense pull of gravity. Researchers confirmed that this enormous structure existed when the Universe was in its infancy—merely 1.2 billion years old—offering unprecedented clues into how the earliest cosmic systems formed and evolved.

The Unique Parallel to Manipur’s Iconic Lake
Dr. Laishram, currently a scientist at the National Astronomical Observatory of Japan (NAOJ) in Tokyo, explained that naming the structure after Manipur’s famous Loktak Lake was a heartfelt tribute to his homeland.
The name also reflects a fascinating structural parallel between the earth and the deep cosmos:
- The Earthly Loktak Lake: Famous for its unique ecosystem featuring floating islands of vegetation called phumdis, which exist as separate masses within a single, connected body of water.
- The Cosmic Loktak Protocluster: Contains four distinct galaxy concentrations completely linked together as one large, evolving cosmic system.
“Loktak is deeply connected to Manipur’s identity,” Dr. Laishram stated. “Naming this discovery after Loktak Lake is my way of connecting our home with the wider Universe. In that sense, the name Loktak will continue to echo in the story of the Universe.”
How the Surroundings Shape Galaxy Growth
To peer across 12.6 billion light-years of space, the international research team pooled data from two of mankind’s most powerful skyward eyes: the Subaru Telescope and the James Webb Space Telescope (JWST).
Their observations have delivered critical new insights into dark matter environments. The study explicitly suggests that galaxies residing within dense, highly crowded regions of the early Universe evolved vastly differently from those in isolated areas. This strongly indicates that a galaxy’s cosmic surroundings and environmental neighborhood play a dominant role in shaping how it grows, births stars, and matures over deep time.
From Khangabok to Tokyo: The Inspiring Journey of Dr. Ronaldo
Hailing originally from Khangabok in Manipur’s Thoubal district, Dr. Ronaldo Laishram’s tryst with space began incredibly early. At just 18 years old, he successfully identified a preliminary asteroid, an achievement that earned him high praise and an honor from India’s former President, Dr. A. P. J. Abdul Kalam.
He went on to complete his Master’s and PhD in astronomy at Tohoku University in Japan before transitioning into his current role at the NAOJ. Beyond his elite research mapping galaxy formation, Dr. Laishram remains deeply committed to regional development. He is the founding coordinator of the Manipur Astronomical Society, which spreads scientific awareness among students across Northeast India, and actively mentors youth through educational initiatives like OviEdu and the MitSna Foundation.
State Leadership Celebrates Historic Feat
The monumental discovery triggered widespread celebration across the region. Former Manipur Chief Minister N. Biren Singh took to social media platform X to extend his warmest congratulations to the young scientist, hailing the breakthrough as a historic achievement that brings global honor to the state. Singh noted that embedding the name of Loktak into the overarching tapestry of cosmic history is a moment of profound pride for all Manipuris, expressing hope that Dr. Ronaldo’s journey would inspire the next generation of regional youth to aggressively pursue science, tech, and space innovation.
