The Marvelous benefits of James Webb Telescope are reaching-up to brighten the knowledge about the early stages of our own galaxy which could open up newest vistas of understanding with regards the formation of Milky way and its early progression by an interesting mirroring with a recently discovered galaxy aptly named Sparkler to unearth wealth of information we are aiming at .
Astronomers believe the Milky Way is an estimated 13.51 billion years old. Yet many details of its life remain unclear, such as what happened during its infancy and what the galaxy was like as a so-called newborn.
This research published in Monthly Notices of the Royal Astronomical Society, provided astronomers with new details about a recently discovered galaxy, nicknamed “The Sparkler,” which can be found in the constellation of Volans in the southern sky. The new observations have scientists comparing this younger galaxy, which is around 9 billion years ago, to our own when it was that age. In other words, this newly-discovered galaxy could have characteristics very similar to the Milky Way when it was merely a baby galaxy.
“We appear to be witnessing, first hand, the assembly of this galaxy as it builds up its mass – in the form of a dwarf galaxy and several globular clusters,” said lead researcher Duncan Forbes in a statement. “We are excited by this unique opportunity to study both the formation of globular clusters, and an infant Milky Way, at a time when the Universe was only 1/3 of its present age.”
What led astronomers to compare The Sparkler to The Milky Way is that they discovered it’s located in a system of ancient star clusters — known as globular clusters— and is essentially swallowing these stars as it grows, which is what the Milky Way has done. However, overall, globular clusters are a mystery to astronomers.
Globular clusters are highly concentrated collections of around a million stars. Through the brightening effect of gravitational lensing — which is when light from a galaxy is diverted by a massive object en route to Earth — scientists were able to conclude that they were seeing The Sparkler around 9 billion years ago, which would be nearly 4 billion years after the Big Bang. Through this observation .. it was a “surprise” to see that the globular clusters were still really old in this young galaxy .Our galaxy is middle-aged right now, you could say we understand it’s young adulthood, we understand it’s adolescence, but it’s really childhood we don’t know much about and that’s where the globular clusters come in.” However, as the James Webb Telescope collects more data it’s likely that we’ll have more answers. Indeed, one of the Webb telescope’s primary goals is to explore what happened during the very early universe. By peering back into time, astronomers anticipate they’ll have a better understanding of how our galaxy got to its current form today.
But for now, Researchers remain perplexed and believe in the heart of their hearts, that this discovery tends to lead to more fundamental questions at the very making of the Milky way in its origins and beyond. ”
This proves to be, though early state, a tremendous leap into the nascent development of our own Milky way galaxy and its evolution into higher configurations .with wide acknowledgement of the contributions from James web telescope forming an amicable partner in unraveling the mysteries of Milky way in all its grandeur in particular and the Big Bang theory in general.
