I have to believe that it is a good thing that there are intelligent and inquisitive people who are continuously delving into studies of such intrigue! Surely, it has to take some time and work for these kinds of results to be produced with such seeming accuracy and allure. The information that is being released is so fantastic and phenomenal that it certainly must attract the attention of any who come across the details presented!
Details that have been published within the recent edition of The Astrophysical Journal provide data about what is being labeled as the smallest galaxy to be discovered, yet! It has been entitled as Segue 2. This is a dwarf-spiral galaxy, and it is a satellite galaxy of our Milky Way. It is said to be filled with stars that mostly are ancient, having been formed more than twelve billion years in the past. Scientific speculation has presented the supposition that Segue likely was one of the first galaxies to have been formed ever, with it’s stars being among the first ever to shimmer within all of space-time!
Current studies of Segue 2 are leading to more detailed studies of dark matter. This is the theoretical matter that is alleged to compose nearly eighty-five percent of all matter within the entire universe! First identified in the early twentieth century by scientific minds like Fritz Zwicky, dark matter continues to captivate the minds of the scientific community, while there has been no direct identification of it, or contact with it.
Dark matter is relevant in the study of Segue 2 in that it is alleged to be the primary bonding force of this galaxy’s structure. Scientists working with The University of California – Irvine have observed Segue 2, finding that it is a galaxy of little actual mass, and containing slightly more than one thousand stars, at most. Their studies go further, proposing that the galaxy is held in tact by dark matter.
As a dwarf-spiral galaxy, Segue 2 is far smaller than our Milky Way. However, it is believed to have a greater density than our home galaxy. This is due to it having slightly more than one thousand stars within it, yet being filled with dark matter. It is due to the presence of a dark matter halo that the stars within Segue 2 remain in place, allowing the collection to maintain the classification of galaxy.
Currently, researchers are combining skills and information to get more clarified results from the studies of Segue 2. Scientists working with The University of California – Irvine are reviewing information about this galaxy, while seeming intrigued at it’s small size, yet intense density. Their studies are providing new light into how dark matter works, and the possibility of a not-yet discovered subatomic particle, which also may play a role in how structures like entire galaxies contain and maintain mass. The scientists look into details of Segue 2 with awe, as some have said that it’s discovery has been like finding an elephant that is smaller than a mouse!
