Getting closer to our own Milky Way, there is a tiny galaxy that astronomers named Triangulum II and it contains only one thousand stars, an extremely small figure in comparison to approximately 100 billion suns in our galaxy. Its period of star creation is far-gone, making it a dead galaxy that roams across the space. However, Triangulum II could have an astonishing secret, which makes this galaxy the most exciting ghost entity in the visible cosmos.
The close star gathering may possess the maximum percentage of dark energy and matter ever discovered in a galaxy. In the document released this week in the astronomy publications, scientists say that the strange and hidden matter could be accountable for Triangulum II incredibly low number of stars.
Specialists are currently trying to understand how little this dark matter can interact with regular matter and energy, these forming a large part of the visible space. For now, their answer appears to be that both sides interact with each other very little, yet enough to maintain a certain level of dynamics in the cosmos.
As always, experts in this research are discovering dark matter only by observing its various effects on the surrounding areas and the lack of other space objects that could cause those unusual phenomena. The entire mass calculated by astronomers was simply too much, offering a lot larger figures than the ones based only the 1,000 stars, meaning that there are huge amounts dense dark matter adding to the entire mass.
To calculate the gravitational force affecting the internal mechanisms of the Triangulum II and discover the effects of dark energy and matter on the visible space objects, the specialists had to depend on a very limited number of stars seen in the galaxy, since all the others were too dim for observation.
The percentage of dark matter compared to regular matter is by far the biggest of any space patch studied until now, simply baffling the experts who studied the galaxy. It is possible that this unusual galaxy is not as large as these theoretical dimensions indicate and this would eliminate the need to have dark matter as the only explanation. Another analysis team has said that the little galaxy is actually being ripped apart by our much larger and powerful Milky Way.
This theory would be confirmed by stars found on the side that are moving quicker than the objects in the center and could distort the type of research that astronomers used for their conclusion. The people who took part in the newest study are analyzing this probability, but they still want to confirm that the small galaxy really is filled with dark matter.
In that case, the galaxy could be the best subject for attempting to identify the gamma radiation that some dark matter particles generate when they hit each other at extremely high speeds in space. It is usually challenging to identify these gamma radiations in the immensity of the universe, but the recently discovered galaxy is dead, so astronomers could study it in depth.
