Dozens (if not hundreds) of science fiction films begin like this: something incredible opens up in the sky, revealing new truths to scientists. But if the textures of sci-fi films can be alarming, the spiral of stars found by NASA’s Hubble telescope just shows us something we might be really, really curious about.

Yes, because according to what Hubble showed there is a cluster of young stars that is whirling towards the center of a cluster of celestial bodies in that of the Little Magellanic Cloud, a satellite galaxy of the Milky Way. What does it mean, in a nutshell? That a window has opened on a Primordial Universe.

The spiral of stars and the Primordial Universe

Words that are a bit complex and certainly suggestive, but which actually have a very simple and concrete meaning. In practice, the outer arm of the spiral of this cluster of stars moves in a particular way. A way that could feed and justify the formation of new celestial bodies, thanks to the movement of gas and clusters of solid objects.

According to researchers who observe space from the Hubble telescope, therefore, this enormous “nest” of spiral stars, called NGC 346it could be showing us how a Primordial Universe is formed, revealing more information on how our Universe was born (and evolved).

NGC 346 and its particularities

It should be noted that, in reality, astronomers, astrophysicists and researchers have been keeping an eye on NGC 346 for some time. This massive star cluster has always intrigued experts precisely because of its spiral shape. It took some time, however, to establish that this very characteristic shape is due to a movement similar to that of a riverwhich “flows” and swirls towards the center.

On the other hand, NCG 346 and, more generally, the Little Magellanic Cloud, have one chemical composition simpler than the Milky Way. This makes it really more similar to what our Universe was at the beginning, when the heavier elements were scarce and the stars burned more evidently and conspicuously. Understanding, therefore, how stars (and planets?) Are formed in this part of space offers a new perspective on what would have caused the Big Bang.

Will the spiral of stars form a new Universe?

Will the spiral of stars then form a new Universe? And what does all this imply? In reality, NGC 346 is relatively far from us and the amount of movement observed is still too difficult to measure in detail. It will take some time (and even more precise resolutions and sensitivities than the Hubble telescope) to really know what will happen in this portion of the space.

For sure, the behavior of NGC 346 confirms that the entire Universe is constantly moving and evolving and can explain to us in which direction we have gone in the past. Furthermore, revealing to us what could await us in the future, considering that in the coming decades it is not excluded that new “spirals” will open, always revealing something new, different, enlightening and suggestive.
