Study of stars

study-starsThe orbital motion of the stars has always been a subject of exploration and the latest study by the astronomers using Hubble space telescope has resulted in a series of findings. The orbital motion of two different star populations that belong to an ancient cluster has been determined.

The latest observations of the telescope along with loads of data stored in archives have been used to substantiate the current results. The stars’ motion is closely related to the ages of the stars and the two distinct star populations taken for study differ by not more than 100 million years in age. This will enable the astronomers to analyze the various ways with which stars in clusters are formed.

When the time baseline for the stars is taken for observation, the motion of stars is clearly obtained which paved way for analyzing the individual motion. The study also substantiates the fact that various chemicals are present in the stars which result in obtaining various theories for the formation of stars and galaxies. Various cameras were used for the study and the latest among them was the advanced camera of Hubble which was used in 2010. The camera took images of the stars for close analysis.

Along with the images taken during this time, the archival images of analysis performed in the previous years were also taken for consideration. The movement of 30, 000 stars were analyzed and their change in position were measured. This data helped in the measurement of age of stars and its movement. The two different populations of stars are the redder stars and bluer stars with the former being the older ones and the latter being the younger ones.
