Hubble Telescope Helps Track The Dynamic Aging of Star Clusters

Our galactic neighbor, the Large Magellanic Cloud (LMC) galaxy, has been recently captured by the Hubble telescope. The current image shows the object named NGC 1466, which is a particular type of star cluster named globular cluster, to provide a clear picture of how the stars connected by gravity tend to move across the edges of the LMC. It is found to be distanced almost 160,000 light-years away from Earth. This cluster of stars is found to weigh almost 140,000 times of our Sun. It is found to be extremely old as our Universe that is about 13.1 billion years old. The Hubble shows the scenic picture to reveal quite a lot about the star clusters’ evolution and expansion rate.

The star clusters are active and show changes in the structure with time and the larger stars among them are found to move toward the center. The core of the cluster is found to shrink as time goes by. The star cluster found in the LMC is rare as the younger stars are compact while the older ones diffuse and compact at the same time. The blue straggler or re-invigorated star can help understand the cluster better. The stars have been found to gather more fuel as they travel and turn brighter. The stragglers are pulled to the middle of clusters as they are heavier. The blue stragglers and different structures of star clusters in LMC clusters could help rank the clusters in order of age. Thus, it is for the first time that Francesco Ferraro of the University of Bologna has been able to record the effect of dynamical aging in the LMC clusters.

Parallelly, the Hubble telescope has been able to capture some spectacular images of the rings of Saturn. NASA and the European Space Agency have recently unveiled the new Saturn portrait. The astronomers are trying to study the gas giant planet’s changing weather patterns and other alterations to identify trends. The image shows Saturn’s moons and other Saturnian moons like icy Janus, Enceladus, and Tethys. Thus, the Hubble telescope provides a clear picture of the bands, clouds, atmosphere, and moons of the gaseous planet.
