The Milky Way Galaxy as a baby is revealed



Firefly Sparkle has not yet been assembled, but it is estimated to have a mass of 10 million solar masses.

James Webb Space Telescope of Nasa has made an important discovery. It identified a galaxy called Firefly Spangle, which dates from the early universe.


This galaxy, which resembles bioluminescent stars due to its shining star clusters gives astronomers a unique insight into how the Milky Way might have looked at its infancy.


Firefly Sparkle, located approximately 600 million year after the Big Bang is still in the assembling process and has a weight equivalent to 10 million solar masses.


This galaxy has ten star clusters that are densely packed. Eight of them are located in the central region, and two others along an extended arm. It is approximately 1,000 light years across. This formation is a major evolutionary stage in the evolution of galaxies at this time.


Lamiya Mowla is an astronomer from Wellesley College, and the co-author of the Nature study. She stressed the importance of her observation: "The Milky Way formed very early in the history of the universe, probably around the time of Firefly Sparkle."


Firefly Sparkle was about 10,000 times smaller than our Milky Way at the time.


The galaxy looks like a bunch of fireflies, hence the name "Firefly Sparkle".


Mowla explained that "a group of fireflies" is called a'sparkle.' The galaxy was accompanied by Firefly Best Friend and Firefly New Best Friend. All of these would have fit within the Milky Way of today.


Researchers believe that the formation of early galaxies such as Firefly Sparkle was caused by the collapse under extreme conditions of dense gas clouds. Kartheik, a co-lead researcher and Nasa Hubble fellow at Columbia University, said that these galaxies are built up by interactions and mergers of smaller galaxies.


Webb's advanced abilities allowed scientists to observe Firefly Sparkle with unprecedented detail. gravitational lenses from a foreground galaxycluster magnified the light by 16-26.


This allowed astronomers examine different star clusters in the galaxy. The varying colors indicate different stages of formation.


Webb's exploration of the cosmos continues, and discoveries such as Firefly Sparkle have reshaped our understanding of galaxy evolution in the earliest times.
