Even if spiral galaxies or nebulae catch the eye of the general public, seeing how Hubble takes an impressive photo of Trumpler 14, open star clusters could easily be classified as one of the most beautiful cosmic structures out there. This cluster is located in the Carina Nebula, roughly 8,000 light-years away from Earth.
Because Trumpler 14 is fairly young, with its birth being dated back to roughly 500,000 years ago, it encapsulates some of the brightest stars in the Milky Way. This effectively qualifies the cluster as the brightest and probably the most beautiful, being easily compared to a tapestry of brightly lit diamonds across a velvet sheet of silk.
But due to the intense brightness of its stars, Trumpler 14 will be subjected to numerous supernovae in roughly 5 million years. True, the human race will more than likely be extinct by that point, but the supposed image created by those events would be incredibly superb. The stellar winds created by these events, as well as the massive amounts of cosmic dust released into space, will give birth to cavities withing Trumpler 14.
But that period will not be one of mourning. This constant cycle of star death and rebirth happens everywhere around us as we speak. The matter flung from supernovas will create more stars along the way as it collides with other particles within the galaxy.
This phenomenon can be seen at the bottom of the picture in the form of an arc. This bow shock is created by stellar wind from the star named Trumpler 14 MJ 218 that travels at 217,000 miles per hour. While traveling at this immense speed, the star molds and shapes the cosmic dust around it, heating up gases, effectively sparking the creation of new stars.
The structure composition of Trumpler 14 is made out of 2,000 stars with sizes varying from one tenth to up to tens of times the size of our very own Sun. The brightest star in the cluster, which incidentally is the one of the brightest in the Milky Way galaxy is HD 93129Aa super-giant. This star is also the hottest one.
Even if Hubble takes an impressive photo of Trumpler 14, a plethora of other wondrous cosmic structures, galaxies and nebulae are constantly changing everywhere in our universe, making us able to witness their splendor from the comfort of our little blue planet.
